Question

A normal gamete (sperm and egg) has ______ allele for each trait.

Answer 1

A normal gamete (sperm and egg) has one allele for each trait. This is because during meiosis, the diploid cell (with two copies of each chromosome) undergoes two rounds of division, resulting in four haploid cells (with one copy of each chromosome). Each of these haploid cells (gametes) receives one copy of each chromosome and thus one allele for each trait.
