Incomplete dominance in horses
WebThe cream mutation shows incomplete dominance, so that one copy of the cream allele (heterozygous) produces a dilute phenotype and two copies of the cream allele (homozygous) produces a more extreme dilute phenotype. Mating a cream horse (Cr/N) to a non-cream horse (N/N) will result in a 50% chance of producing offspring with the cream …

WebIf we had a gray heterozygous mare and a gray heterozygous stallion, i.e. both of genotype G + G G then the cross would be as follows: Altogether there’s a 75% chance of a gray foal (25%+25%+25%). Another way of saying this is that there’s a 3:1 ratio of gray to not gray.
