Question

An organism with two copies of the same allele is ______.

विकल्प

• homozygous for that trait

• heterozygous for that trait

• homologous for the allele

• heterologous for the allele

Answer 1

An organism with two copies of the same allele is homozygous for that trait.

Explanation:

An organism that has two copies of the same allele for a trait is said to be homozygous. This means both alleles at a gene locus are identical, either both dominant or both recessive. In contrast, heterozygous organisms have two different alleles for that trait. The term “homozygous” helps describe the genetic makeup (genotype) related to a particular characteristic or trait in an organism.
