Question

Define the following terms

6. (a) Allele (b) Dominant gene (c) Genotype (d) Phenotype ​

Answer 1

Explanation:

1) each of two or more alternative forms of a gene that arise by mutation and are found at the same place on a chromosome

2) In genetics, dominance is the phenomenon of one variant of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome. The first variant is termed dominant and the second recessive

3) A genotype is an organism's complete set of heritable genes, or genes that can be passed down from parents to offspring. These genes help encode the characteristics that are physically expressed (phenotype) in an organism, such as hair color, height, etc.

4) the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.

hope it helps!!

Answer 2

Explanation:

Allele:-

An allele is a variant form of a given gene, meaning it is one of two or more versions of a known mutation at the same place on a chromosome. It can also refer to different sequence variations for a several-hundred base-pair or more region of the genome that codes for a protein.

======================================

b) Dominant gene:-

In genetics, dominance is the phenomenon of one variant of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome. The first variant is termed dominant and the second recessive.

=========================================

c)Genotype:-

A genotype is an organism’s complete set of heritable genes, or genes that can be passed down from parents to offspring. These genes help encode the characteristics that are physically expressed in an organism, such as hair color, height, etc.

=========================================

d) Phenotype:-

Phenotype is the term used in genetics for the composite observable characteristics or traits of an organism. The term covers the organism's morphology or physical form and structure, its developmental processes, its biochemical and physiological properties, its behavior, and the products of behavior.
