Which of the following is true for organisms that have two identical alleles for a particular trait?

Question

A.
They are hybrids.

B.
They are homozygous.

C.
They are heterozygous.

D.
They are dominant.

Answer 1

The correct answer is:

B. They are homozygous.

Homozygous organisms have two identical alleles for a particular trait, while heterozygous organisms have two different alleles. Hybrid is a term that often refers to heterozygous organisms. Dominance refers to the relationship between alleles, not the genetic makeup itself.
