Solution

The correct option is B

one


2-Alleles of a trait are present on homologous chromosome pair in a cell. During gamete formation, only one chromosome is transferred to each gamete or sex-cell. In other words, each gamete is receiving only one allele as it gets only one chromosome out of two. Thus, gametes produced by parent contain ONE allele for a trait.
