Question

Generally, there are two copies of a set of genes in body cell, then how do germ cells make a single set of genes​

Answer 1

Explanation:

There are 22 chromosomes pairs (autosomes) and a pair of sex chromosomes (allosomes). Thus, a single set of genes is formed from the two copies. ... Meiosis, therefore, helps the germ cells make a single set of genes (haploid) from the normal two copies (diploid).
