검증된 단계별 안내1
Understand that fur color in this population of cats is determined by a single gene with two alleles: B (black) and b (white).
Recognize that the genotype Bb consists of one dominant allele (B) and one recessive allele (b).
Recall that the presence of a dominant allele (B) will mask the expression of the recessive allele (b), resulting in the dominant trait being expressed.
Identify that the dominant trait for fur color in this scenario is black, as indicated by the allele B.
Conclude that females with the genotype Bb will have black fur, as the dominant allele B determines the fur color.
