A. The parent combination of pure white and pure black will yield only white offspring.
B. The parent combination of two hybrid black parents will yield only black offspring.
C. The parent combinations of hybrid black and pure black, and pure white and hybrid black, will yield a mixture of black and white offspring.
A. The parent combination of pure white and pure black will yield only white offspring. This is because the offspring will inherit a white allele from the pure white parent and a white allele from the pure black parent. The white allele is dominant over the black allele, so the offspring will be white.
B. The parent combination of two hybrid black parents will yield only black offspring. This is because the offspring will inherit a black allele from each parent. Since the black allele is dominant over the white allele, the offspring will be black.
C. The parent combinations of hybrid black and pure black, and pure white and hybrid black, will yield a mixture of black and white offspring. This is because the hybrid black parent carries both black and white alleles, while the pure black parent carries only the black allele. The offspring will inherit either a black or white allele from the hybrid black parent, and a black allele from the pure black parent. The resulting offspring will have a combination of black and white alleles, leading to a mixture of black and white fur or traits.
