Created by StemPy LabA woman of blood group A had a father of group O. She marries a man of blood group B whose mother was of group O. Both are Rh positive, and each had an Rh negative parent. Rh positive is dominant to Rh negative, and the Rh gene and the ABO gene assort independently. They have two children. What is the probability that the two children differ in blood group or in Rh type, or in both?

← Two large populations of the same species each mate at random. Population X has 600 individuals and the frequency of a recessive allele a is 0.10. Population Y has 400 individuals and the frequency of a is 0.40. Before the next breeding season all 1000 individuals mix completely and breed at random as one population. The trait is autosomal with complete dominance. What fraction of the next generation is expected to show the recessive trait?A rare recessive autosomal condition has an allele frequency of q = 0.01 in a large, randomly mating population. The inbreeding coefficient of a child of first cousins is F = 1/16. How many times greater than the risk for a child of unrelated parents is the risk of the condition for a child of first cousins? →
