Consider a gene with two alleles that show complete dominance. When a homozygous recessive individual (qq) is crossed with a heterozygous individual (Qq), they have a 50 percent chance of producing a homozygous recessive offspring. The next time these two individuals breed, what are the chances that they will once again have a homozygous recessive progeny?
A. 0 percent
B. 50 percent
C. 75 percent
D. 25 percent
B. 50 percent
Each time the two individuals breed, there is a 25 percent chance of producing a homozygous recessive offspring (qq). Therefore, the chances of having a homozygous recessive progeny the next time they breed is 50 percent.
