4. Direction: Define the following terms.1. Genetics-2. Heredity-3. Gametes-4. Punnett Square-5. Incomplete dominance-6. Codominance-7. Multiple Alleles-8. Sex-linked traits-9. Sex-limited traits-10. Sex- influenced traits-
Answer:
Genetics is a branch of biology concerned with the study of genes, genetic variation, and heredity in organisms. Though heredity had been observed for millennia, Gregor Mendel, a scientist and Augustinian friar working in the 19th century, was the first to study genetics scientifically.
Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents.
Gametes are an organism's reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome.
The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. It is named after Reginald C. Punnett, who devised the approach. The diagram is used by biologists to determine the probability of an offspring having a particular genotype.
Incomplete dominance is when a dominant allele, or form of a gene, does not completely mask the effects of a recessive allele, and the organism's resulting physical appearance shows a blending of both alleles. ... Note that this is different from codominance, which is when both alleles are expressed at the same time.
Codominance is a relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent. ... In codominance, however, neither allele is recessive and the phenotypes of both alleles are expressed.
Multiple Alleles are three or more possible alleles for one individual trait.
Sex linked is a trait in which a gene is located on a sex chromosome. In humans, the term generally refers to traits that are influenced by genes on the X chromosome. ... In a sex-linked disease, it is usually males who are affected because they have a single copy of X chromosome that carries the mutation.
Sex-limited genes are genes that are present in both sexes of sexually reproducing species but are expressed in only one sex and have no penetrance, or are simply 'turned off' in the other. In other words, sex-limited genes cause the two sexes to show different traits or phenotypes, despite having the same genotype.
A phenotypic characteristic or trait such as male pattern baldness that is expressed differently in males and females, usually because its expression depends on androgens or oestrogens, and that is controlled by a single gene that is dominant in males but recessive in females, so that, for example, men who inherit the gene from either parent lose hair as they age, whereas women do so only if they inherit it from both parents and are thus homozygotes. Also called a sex-limited trait. Compare sex-linked.

6. what is a punnett square?
Answer:
The Punnett square is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. It is named after Reginald C. Punnett, who devised the approach[3]. The diagram is used by biologists to determine the probability of an offspring having a particular genotype. The Punnett square is a tabular summary of possible combinations of maternal alleles with paternal alleles.[4] These tables can be used to examine the genotypical outcome probabilities of the offspring of a single trait (allele), or when crossing multiple traits from the parents. The Punnett square is a visual representation of Mendelian inheritance. It is important to understand the terms "heterozygous", "homozygous", "double heterozygote" (or homozygote), "dominant allele" and "recessive allele" when using the Punnett square method. For multiple traits, using the "forked-line method" is typically much easier than the Punnett square. Phenotypes may be predicted with at least better-than-chance accuracy using a Punnett square, but the phenotype that may appear in the presence of a given genotype can in some instances be influenced by many other factors, as when polygenic inheritance and/or epigenetics are at work.

9. 3. If a male has a disease that is Y-linked, what percentage ofhis sons will inherit the disease? Draw the Punnett square andexplain your answer.
Answer:
25%
Explanation:
A condition is considered Y-linked if the altered gene that causes the disorder is located on the Y chromosome, one of the two sex chromosomes in each of a male's cells. Because only males have a Y chromosome, in Y-linked inheritance, a variant can only be passed from father to son

20. 1. Define/ Describe the following:1. DNA2. Heredity3. Gamete4. Dominant traits5. Recessive traits6. Allele7. Genotype8. Phenotype9. Homozygote10. Heterozygote11. Punnett Square
Answer:
1. DNA- The molecule inside cells that contains the genetic information responsible for the development and function of an organism.
2. Heredity - the sum of all biological processes by which particular characteristics are transmitted from parents to their offspring.
3. Gamete- sex, or reproductive, cell containing only one set of dissimilar chromosomes, or half the genetic material necessary to form a complete organism (i.e., haploid). Gametes are formed through meiosis (reduction division), in which a germ cell undergoes two fissions, resulting in the production of four gametes. During fertilization, male and female gametes fuse, producing a diploid (i.e., containing paired chromosomes) zygote.
4. Dominant Traits- in genetics, a trait that will appear in the offspring if one of the parents contributes it.
5. Recessive Traits- In genetics, a trait that must be contributed by both parents in order to appear in the offspring. Recessive traits can be carried in a person's genes without appearing in that person.
6. Allele- An allele is one of two or more versions of DNA sequence (a single base or a segment of bases) at a given genomic location. An individual inherits two alleles, one from each parent, for any given genomic location where such variation exists. If the two alleles are the same, the individual is homozygous for that allele.
7. Genotype- is a scoring of the type of variant present at a given location (i.e., a locus) in the genome. It can be represented by symbols. For example, BB, Bb, bb could be used to represent a given variant in a gene.
8. Phenotype- the observable characteristics or traits of an organism that are produced by the interaction of the genotype and the environment : the physical expression of one or more genes.
9. Homozygote- an individual having two identical alleles of a particular gene or genes and so breeding true for the corresponding characteristic.
10. Heterozygote- an individual having two different alleles of a particular gene or genes, and so giving rise to varying offspring.
11. Punnette Square- is a square diagram that is used to predict the genotypes of a particular cross or breeding experiment. It is named after Reginald C. Punnett, who devised the approach in 1905. The diagram is used by biologists to determine the probability of an offspring having a particular genotype.
21. what is Punnett square ? ,how is it important of Punnett square in the field of genetics?

(Answered by Knowledge original and Valid Opinions to help and guide the questioners)
1. A. Mitosis produces two cells, each with the same chromosome number as the original cell. Meiosis produces four cells, each with half the chromosome number as the original cell.
B. Mitosis produces two daughter cells that are exactly the same as their parent cells. Meiosis produces four daughter cells with unique combinations of chromosomes.
C. Mitosis is used for repairing, replacing, and growth of cells. Meiosis is used for the production of gametes in sexually reproducing organisms.
2. A. Mitosis is used for growth and repair and is an important part of a cell's life cycle. Meiosis is used for the production and fertilization of gametes.
B. Mitosis involves four stages: interphase, prophase, metaphase, and telophase. Meiosis involves two alternating cell divisions, meiosis I and meiosis II.
3. A. Heredity is the passing on of certain traits from parent to offspring. Traits are characteristics that are inherited from parents and are passed on through genes.
B. Knowing about heredity and traits helps with understanding how traits are passed down through generations and can be used to predict future generations of organisms.
C. Environmental factors such as diet and climate can affect an organism's phenotype, while genetic factors such as an individual's genotype affects the expression of its traits.
_________________
1. Heredity is the passing of traits from parent to offspring, including physical and inherent traits. It is related to traits in that heredity is responsible for the similarities and differences of all the traits an organism may have.
2. Knowing about heredity and traits can help with genetics by understanding how traits are inherited, how they can be passed down, and how they can change. This can be useful in selecting favorable traits or preventing the transmission of unwanted traits.
3. Environmental and genetic factors both have an effect on an organism's traits. Environmental factors, such as diet and lifestyle, can cause changes in traits. While genetic factors determine the initial set of traits of the organism, with some of them being intrinsic to the individual. Environmental and genetic factors can work together to shape an organism's traits.

1. Genotypes and phenotypes are related in a Punnett square as the genotypes (set of genes) are used to predict the possible phenotypes (characteristics or traits) that could emerge from the genetic combination.
2. The purpose of a Punnett Square in genetics is to visualize the potential offspring from a cross or mating of two parents. It is used to determine the probability of different genotypes and phenotype expressions in the offspring.
3. In the Punnett Square, genotypes are responsible for the formation of phenotypes by combining the alleles of each parent. The alleles line up along two axes of the Punnett Square and the possible gene combinations are visualized as squares in the grid. Depending on the alleles that are present, different phenotypes can be expressed by the offspring.
