Question

When gametes are formed, each gamete has only ______ allele of the pair.

Answer 1

When gametes are formed, each gamete has only one allele of the pair.

Explanation:

When gametes are formed, each gamete has only one allele of the pair. This happens because, during gamete formation (meiosis), the two alleles for a trait segregate or separate from each other so that each gamete receives only one allele. This principle is known as the law of segregation, which ensures that offspring get one allele from each parent, maintaining genetic variation without blending of traits.
