Question

18 multiple choice 15 points in a complementation test, two independent mutant strains showing similar phenotypes were conjugated. the zygote did not show either of the mutant phenotypes. you may likely conclude that the mutations are in the same gene the mutations are in different genes the mutations are located on the same chromosome one mutation is epistatic to the other

Explanation:

In a complementation test, when the zygote does not show the mutant phenotypes of the parent strains, it implies that the mutations are in different genes. Each mutant strain has a wild - type allele for the gene that is mutated in the other strain, which complements the mutation and restores the normal phenotype.

Answer:

The mutations are in different genes
