3 8334Flower position, stem length, and seed shape were three traits that were studied by Mendel. Each is controlled by an independently assorting gene. If a plant that is heterozygous for all three traits was allowed to self- fertilize, what proportion of the offspring would be expected to show all three dominant phenotypes?

In mice colored coat is dominant to albinism. Sniffles, a male mouse with a colored coat is mated to Esmeralda, an alluring albino. The resulting litter of six young all had colored fur. The next time around Esmeralda was mated with Whiskers, who was the same color as Sniffles; some of this litter were white. a)What are the probable genotypes of Sniffles, Esmeralda, and Whiskers? b) If a male of the 1st litterwas mated to a colored female of the 2nd litter, what phenotypic ratio might be expected among the offspring? c)What would be the expected results if a male of the 1st litter was mated to an albino from the 2nd?

The ABO blood system has been employed to settle cases of disputed paternity. Suppose, as an expert in genetics, you are called to testify in a case where the mother is type A, the child is type O and the alleged father is type B. How would you respond to the following statements of the attornies: a. "Since the mother has type A, the type O of the child must have come from the father and since my client is type B, he obviously could not have fatered the child." Made by the attorney of the alleged father. b. "Further tests revealed that this man is heterozygous and therefore he must be the father." Made by the mother's attorney.
