Ответ:
Probability that at least one of them will be affected = 3/16 + 3/16 + 1/16 = 7/16
Explanation:
If both parents are heterozygous for a genetic disease; Xx and Xx
The offspring's they will produce will be as follows ; XX, Xx, xX, xx
Probability that first child will be affected = 1/4Probability that first child will not be affected = 1 - 1/4 = 3/4Probability that first child have it and second does not = 1/4 x 3/4 = 3/16Probability that first child does not have it, second child have it = 3/4 x 1/4 = 3/16Probability that both of them will have it = 1/4 x 1/4 = 1/16Hence, Probability that at least one of them will be affected = 3/16 + 3/16 + 1/16 = 7/16Ответ:
