In dogs, wire hair (S) is dominant to smooth (s). In a cross of a homozygous wire-haired dog with a smooth-haired dog, what will be the phenotype of the F1 generation?
You're crossing the genotype SS with the genotype ss, so you get four boxes with the genotype Ss. This represents 4 wire-haired dogs since wire hair is dominant to the smooth. The recessive allele is not expressed; this is also known as complete dominance. The 'S' allele produced enough proteins for the trait to be expressed in phenotypic form.
