Explanation:

Possible phenotypes: brown and white hair rabbit

Genotypes: QQ, Qq, qq

Genotypic ratio: 1:2:1

Answer 2

Answer:

Gene:

• A gene is the fundamental or the basic unit of heredity.
• It can also be referred to as the functional unit of heredity.
• They are made up of DNA.
• Each chromosome consists of many genes.

Allele:

• Alleles are basically each of two or more than two alternative forms of a gene.
• Alleles are a result of mutation.
• They are found at the same place on a chromosome.

In the given question, the gene for hair color in rabbits has two alleles Q and q.

• Q is dominant and codes for brown hair.
• q is recessive and codes for white hair.

Genotype: QQ (brown hair), Qq (brown hair), qq (white hair)

Ratio: 1:2:1

Phenotype: QQ (brown hair), Qq (brown hair), qq (white hair)
