In a certain breed of chicken, two genes control color. A dominant allele (I) inhibits the expression of any color gene
(C). The recessive allele (c) results in albinism when homozygous (cc). Give the F2 phenotypic ratio of a cross between a
colored chicken (ii CC) with a white chicken (II cc). What will be an ideal response?
ANSWER: 9 I__C__ + 3 I__ cc + 1 ii cc = 13 white + 3 ii C__ = 3 color

Imagine that smurfs live in widely separated groups and rarely interbreed, so geneticists know very little about them. On one occasion, two smurfs from different groups did mate. A big-footed, white smurf mated with a small-footed, blue smurf
Three offspring resulted: one big-footed and blue and two small-footed and blue. Which statement about the inheritance of color in smurfs is most likely to be correct? A) Blue is dominant to white. B) White and blue are codominant. C) White is dominant to blue.
You examine a worm that has two genders: males that produce sperm and hermaphrodites that produce both sperm and eggs. The diploid adult has four homologous pairs of chromosomes that undergo very little recombination
Given a choice, the hermaphrodites prefer to mate with males, but just to annoy the worm, you pluck a hermaphrodite out of the wild and fertilize its eggs with its own sperm. Assuming that all the resulting offspring are viable, what fraction do you expect to be genetically identical to the parent worm? Assume that each chromosome in the original hermaphrodite is genetically distinct from its homolog. (a) all (b) none (c) 1/16 (d) 1/256
