Chapter 5, Problem 35P
Two genes control color in corn snakes as follows: O- B- snakes are brown, O-bb are orange, ooB- are black and oo bb are albino. An orange snake was mated to a black snake, and a large number of F1 progeny were obtained, all of which are brown. When the F1 snakes were mated to one another, they produced 100 brown offspring, 25 orange, 22 black, and 13 albino.
a. | What are the genotypes of the F1 snakes? |
b. | What proportions of the different colors would have been expected among the F2 snakes of the two loci assort independently? |
c. | Do the observed results differ significantly from what was expected, assuming independent assort- ment is occurring? |
d. | What is the probability that differences this great between observed and expected values would hap- pen by chance? |

b. What are the genotypes of the F1s?
c. What mode of inheritance is exhibited?

Pigment in mouse fur is only produced when the C allele is present. Individuals of the cc genotype are white. If color is present, it may be determined by the A, a alleles. AA or Aa results in agouti color, while aa results in black coats. (a) What F1 and F2 genotypic and phenotypic ratios are obtained from a cross between AACC and aacc mice? (b) In three crosses between agouti females whose genotypes were unknown and males of the aacc genotype, the following phenotypic ratios were obtained: (1) 8 agouti (2) 9 agouti (3) 4 agouti 8 white 10 black 5 black 10 white What are the genotypes of these female parents?
In silkmoths (Bombyx mori), red eyes (re) and white-banded wings (wb) are encoded by two mutant alleles that are recessive to those that produce wild-type traits (re+ and wb+); these two genes are on the same chromosome. A moth homozygous for red eyes and white-banded wings is crossed with a moth homozygous for the wild-type traits. The F1 have wild-type eyes and wild-type wings. The F1 are crossed with moths that have red eyes and white-banded wings in a testcross. The progeny of this testcross are wild-type eyes, wild-type wings red eyes, wild-type wings wild-type eyes, white-banded wings red eyes, white-banded wings a. What phenotypic proportions would be expected if the genes for red eyes and for white-banded wings were located on different chromosomes? b. What is the rate of recombination between the gene for red eyes and the gene for white-banded wings?
