Solve the problem, rounding the answer as appropriate. Assume that "pure dominant" describes one who has twodominant genes for a given trait; "pure recessive" describes one who has two recessive genes for a given trait; and"hybrid" describes one who has one of each.
-Suppose a hybrid mates with a pure dominant. If they produce two offspring, what is the probability that neither is a hybrid?
A)50
B) 125
C) 25
D) 75

Quizplus · Accepted Answer

When a hybrid (one dominant and one recessive gene) mates with a pure dominant (two dominant genes), the possible offspring genotypes are: 50% pure dominant and 50% hybrid. The probability that neither of the two offspring is a hybrid is the probability that both are pure dominant, which is 0.5 * 0.5 = 0.25 or 25%.
