Question:

What is the difference between autosomes and gametes?

Diploid and Haploid:

Most human cells are diploid, meaning they have chromosomes in pairs. However, sex cells in humans are haploid, containing only one set of chromosomes. When gametes combine, they make a diploid zygote.

Answer and Explanation:

An autosome is one of the numbered, homologous chromosomes in a cell. Autosomes include all chromosomes with the exception of the sex chromosomes (X and Y). Humans have 22 pairs of autosomes in each cell. Autosomes come in homologous pairs, with one set being inherited from each parent.

A gamete is a sex cell. In humans, this includes the sperm and the egg. Gametes contain only one set of chromosomes. So, a human gamete will have 22 autosomes (and one sex chromosome).
