What is the phenotypic ratio of wire-coated to smooth- coated offspring?

Genotype of offspring -Ww

Phenotype of offspring - Heterozygous wire-coated individual

Explanation:

Let us assume that wire-coated hair is dominant to smooth coated hair.

Let the allele for wire-coated trait be represented by "W" and the allele for smooth coated  trait be represented by "w"

Let us say that a true breeding wire-coated individual is crossed with a true breeding smooth coated individual.

Genotype of wire-coated individual will be WW

Genotype of smooth coated individual will be ww

WW * ww

Ww, Ww, Ww, Ww

Genotype of offspring -Ww

Phenotype of offspring - Heterozygous wire-coated individual

equal distribution i think.
