Exam I ID # Genetics 392 F14 Dr.Tomkiel 2. (15 points) True-breeding long-eared white rabbits are mated with true-breeding short-eared gray rabbits. A test cross is performed with the F1, and the following results are obtained 17 long-eared gray rabbits 33 long-eared white rabbits 32 short-eared gray rabbits 18 short-eared white rabbits a. Which of the following is true? (Circle each cor answer) (5 points) The ear-loth gene and coat color geshow independent assortment Short-ears are hypos gray coat color. The domice relationship beten the white and gray alleles cannot be deterred from the information given The coat color and eye color genes must be sex-linked Ear-length and coat color are determined by a single, pleiotropic gone. b. Calculate the genetic distance between the ear length gene and the coat color gene. (5 points) c. If instead of the results obtained above, the ear length and coat color genes showed complete linkage, and white and short-ears are recessive, what would be the ratios of phenotypes observed among the F2 from an F1 test cross? (5 points)
