Question

which example is a variant of a gene?

○ an autosome

○ an allele

○ a chromosome

○ a gamete

Explanation:

To determine the gene variant, we analyze each option:

• An autosome is a non - sex chromosome, not a gene variant.
• An allele is defined as a variant form of a gene. Different alleles can result in different traits.
• A chromosome is a structure that carries genes, not a gene variant.
• A gamete is a reproductive cell (sperm or egg), not a gene variant.

B. an allele
