1 Answer A geneticist crossed wild, gray-colored mice with white (albino) mice. All the progeny were gray. These progeny were intercrossed to produce an F2, which consisted of 198 gray and 72 white mice. Propose an hypothesis to ex- plain these results, diagram the crosses, and compare the results with the predictions of the hypothesis.

1 Answer Mendel crossed pea plants that produced round seeds with those that produced wrinkled seeds and self-fertilized the progeny. In the F2, he observed 5474 round seeds and 1850 wrinkled seeds. Using the letters W and w for the seed texture alleles, diagram Mendel’s crosses, showing the genotypes of the plants in each generation. Are the results consistent with the Principle of Segregation?

(b) The progeny of (a) self-fertilized. (c) The progeny from (a) crossed with the original tall parent. (d) The progeny of (a) crossed with the original dwarf parent.
