•Suppose that in plants, smooth seeds (S) are dominant to wrinkled seeds (s) and tall plants (T) are dominant to short plants (t). A tall plant with smooth seeds was backcrossed to a parent that was short and wrinkled. What proportion of the progeny is expected to be homozygous for short and wrinkled? •Sickle cell anemia is a recessive trait in humans. In a cross between a father who has sickle cell anemia and a mother who is heterozygous for the gene, what is the probability that their first three children will be normal? •A rosy-eyed Drosophila was crossed with a forked Drosophila. The F1 were all wild-type

Unformatted text preview: while the F2 consisted of 306 wild-type, 94 rosy-eyed, 102 fork-bristled and 33 forked-bristled and rosy-eyed flies. Infer the genotypes of the parents. Calculate the probability of the production of a homozygous recessive genotype for the following cross: AaBbccddEeFf AaBbCcddEeFf In corn, three dominant genes are necessary for aleurone color. The genotype B__D__R is colored. Any homozygous recessive for one gene is colorless.
