A male fish from a true-breeding fish line has the mutant phenotype of spiky fin. The male fish mates with a female fish from another true-breeding spiky-fin fish line. Both spiky-fin phenotypes are inherited in an autosomal recessive manner. You hypothesize that the mutation in the male fish is at a different locus than the mutation in the female fish. Which results would support this hypothesis? O 25% of the offspring have spiky fins. Ⓒ 50% of the offspring have spiky fins. O None of the offspring have spiky fins. O All of the offspring have spiky fins. O 75% of the offspring have spiky fins. Incorrect Crossing two mutant animals together will not yield a 50% ratio of any genotype. If the mutation in the male and female are in different genes, their offspring will be heterozygous for two different spiky mutations. Mutations complement when they are in different genes. X X
