Question

If two white guinea pigs with genotype bb are crossed, what is the probability
that the offspring will be white?

Answer 1

Answer:

100%

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.
