Question

1. (4pts) In a strain of rabbits, the allele E (long ear) at the locus for ear length is dominant over the allele e (short ear). The spotted coat allele (s) is recessive when tested against the solid colored coat allele (S). One long eared, solid colored male rabbit is bred to three females. Female A, which has short ears and spotted coat, produces two long eared, solid colored offspring, and one short eared, solid colored offspring, Female B, which is long eared and solid colored, produces two long eared solid colored offspring, one short eared, solid colored offspring, and one long eared, spotted offspring. Female C has short ears and is solid colored. It produces three long eared, solid colored offspring, and three short eared, solid colored offspring. In repeated matings, female C always produces only solid colored offspring a. What are the genotypes of the male and the three females? i. Male = ii. Female A= iii. Female B = iv. Female C = b. What phenotypic ratios do you expect among future offspring of these three matings? i. Male x Female A ii. Male x Female B iii. Male x Female C 2.
