Question
mutation occurs in a germ cell of a pure-breeding, wild-type male fruit fly prior to DNA replication. Tur speranion is not corl deroes The mutation is not corrected, and the germ cell undergoes DNA replication and then a normal meiosis to produce How many of these four gametes will carry the mutation? a. 0 b. 1 C. d. 3 e. 4 3) A female rabbit of phenotype e' is crossed to a male rabbit with eth The Fi is comprised of five rabbits with a e' phenotype, two with eth phenotype, and three with e phenotype. Of the phenotypically e rabbits, two are females and are backcrossed to their father. This cross produces only rabbits with eh phenotype. These results suggest that... a. e is dominant to b.e is dominant to e', but c. e could be dominant or d. c is dominant to ech e. c is recessive to both c' and ch recessive to ech recessive to e' but recessive to e' both c' and echExplanation / Answer
