Question

In sheep, white wool (W) is dominant over black wool (w). What genotype and phenotype ratios are expected from a cross between a heterozygous sheep with white wool and a sheep with black wool?

Answer 2

Answer:

Two black sheep cannot produce white wool in their progeny. Due to the recessive nature of the black wool allele, both parents must be homozygous recessive (ww), which prevents them from having the dominant white wool allele. The black allele is the sole allele that the parents can pass on to their children.

When two black wool sheep that are heterozygous dominant (Ww) join, the recessive gene that each of them has is contributed.

As a result, a sheep with the genotype ww and the phenotypic of having white wool would be born.In a population, dominant genotypes are more prevalent and always have dominant alleles. They may also have recessive alleles. Mendel's Law of Dominance, which stipulates that the dominant allele always controls the phenotype of a heterozygote, is responsible for this phenomena.

In terms of genetics, being homozygous means having inherited the same alleles (versions) of a genomic marker from both biological parents.
