One. A gamete is a haploid cell containing one copy of each  chromosome (23 in humans). Each chromosome contains one copy of  each gene. Therefore, a gamete contains one cop â¦ y of each gene. 2 people found this useful.
All human body cells contain 46 chromosomes (two sets of 23 chromosomes). Only the gametes (i.e., the sperm & eggs) contain 23 chromosomes (one set of 23 chromosomes) because two gametes combine to form a new person with 46 chromosomes in his body cells.Body cells grow and reproduce by the process of mitosis.For each human body cell (with 46 chromosomes) that undergoes mitosis, two identical human body cells (with 46 chromosomes) are produced. Gametes (i.e., sperm & eggs) are produced by meiosis.For example, in the testes of a man, for each body cell (with 46 chromosomes) that enters meiosis, four sperm (with 23 chromosomes) are produced. (Meiosis is a two part process, thatâs why four gametes are produced, not just two).nly the gametes (i.e., the sperm & eggs) contain 23 chromosomes (one set of 23 chromosomes) because two gametes combine to form a new person with 46 chromosomes in his body cells. Body cells grow and reproduce by the process of mitosis.
