In sheep, white fur is dominant to black fur. If two white sheep produce a black offspring, the parent’s genotypes for color must be:
A) Heterozygous.
B) Homozygous white.
C) Homozygous black. D) White
The parents must be heterozygous because they’re dominant for white fur but they also carry that recessive allele for black fur. The offspring will have a 25% chance of having black fur.
