Question

Please Help me word the answer to this problem?A pet store has two guinea pigs. One has white fur and one has black fur. The white guinea pig has two recessive alleles for fur color (bb). The black guinea pig has one dominant allele (B) and one recessive allele (b) for fur color. What will most likely be the phenotypes of the offspring in a cross between the two guinea pigs?Explain your answer

Answer 1

There is a 50% chance that the offspring of guinea pigs will have white fur or black fur phenotype. In the latter case, the genotype will be heterozygous. This character will be determined by the heterozygous parent as it is the one with different alleles, the white fur guinea pig will always always transmit the recessive allele b to its offspring.
