Question

If two white guinea pigs with genotype bb are crossed, what is the probability

that the offspring will be white?

Answer 1

100%

Step-by-step explanation:

If white is the recessive phenotype like the genotype suggests, when you cross the two guinea pigs both with a homozygous recessive phenotype, the only result is offspring that are homozygous recessive for the white hair as well. Attached is a punnet square for the offspring possibilities.
