Question

In dogs, a dominant gene (W) produces wire haired texture. The recessive allele (w) produces smooth hair. A homozygous wire haired male is mated to a female with smooth hair. Show the punnet square. What genotypes and phenotypes are expected in F1 generation, and in what ratio?​

Answer 1

Answer:1. A dominant gene (H) produces wire-haired texture in dogs; its recessive allele (h) produces smooth hair. Two heterozygous wire-haired individuals were crossed and their F1 progeny testcrossed. Determine the expected genotype and phenotype rations among the testcross progeny. Note: in a testcross, an individual with an unknown genotype is crossed with a homozygous recessive individual.
