Question

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

Well first you need to know what a phenotype and genotype is. A phenotype is the physical characteristics and the genotype is the alleles

Answer 2

Next make a punnet square

Answer 3

If there is a (BB) or a (Bb) then the guniea pig will be black, and (bb) means it will be white meaning there is an equal chance of the offspring being black or white
