Question

Black fur (B) in guinea pigs is dominant over white fur (b). What is the probability of finding homozygous black offspring in a cross: BB x BB?

Answer 1

Answer: 100%

Step-by-step explanation: If both guinea pigs are BB dominant, that means they don't have the recessive trait, so therefore no heterozygous guinea pigs will be created. This leaves 100% homozygous offspring.
