Question

BlackTom AI · Accepted Answer

The question asks about the number of pairs of autosomes in a human gamete. Humans have 22 pairs of autosomes in diploid somatic cells, totaling 44 autosomes, plus 1 pair of sex chromosomes for a diploid cell. During gamete formation (meiosis), cells become haploid, meaning they contain only one set of chromosomes. Consequently, a gamete has 22 autosomes, but these are single copies of each autosome type rather than pairs. In other words, there are no autosome pairs within a gamete because pairing occurs between homologous chromosomes in diploid cells, not within individual haploid gametes.

If you think in terms of types, there are 22 distinct autosomal chromosomes, yet each gamete contains only one copy of each type, so the concept of a ‘pair of autosomes’ does not apply to a gamete. This distinction between diploid somatic cells (which have paired homologs) and haploid gametes (which have a single copy of each chromosome) is the key idea here.
