Question

Complementation analysis is used to determine __________.
a. whether a gene is X-linked or autosomal
b. whether two alleles are codominant
c. whether a gene is pleiotropic
d. whether two mutations that produce the same phenotype reside in the same or different genes

Answer 1

Answer:

The correct answer is option d. "whether two mutations that produce the same phenotype reside in the same or different genes".

Explanation:

Complementation analysis, also known as complementation test or "cis-trans" test, is based on exposing the genetic material of a person with homozygous recessive mutation with the genetic material of her or his offspring. Complementation analysis is used to determine whether two mutations that produce the same phenotype reside in the same or different genes. If complementation occurs, it means that the mutations occur at different genes.

Answer 2

Answer: Option D.

Whether two mutations that produce the same phenotype reside in the same or different genes.

Explanation:

Complementation analysis is a process that occur between two strains of homozygous recessive and cause mutations that produce the same phenotype present in the same or different genes when mated or crossed.

Each genetic material provide what the other lacks.
