Question

When mutations exhibit complementation this means the mutations are located:

a. in the same gene
b. in the different genes
c. in between genes
d. in non-coding DNA
e. in introns

Answer 1

The correct option is: b. in the different genes

Step-by-step explanation:

In an organism, complementation is observed when the two strains with the different homozygous recessive mutations are mated or crossed to produce an offspring having wild-type phenotype.

Complementation is observed when the mutations are present in different genes.

Therefore, mutations are said to be complementary, if they are present in different genes.
