- 22 + X chromosome complement will be present in half of the gametes produced by a human male.
- Human males have one X and one Y chromosome in addition to 22 pairs of autosomes.
- During meiosis, the sex chromosomes segregate so that each gamete receives either an X or a Y chromosome.
- This results in two types of sperm: one type with 22 autosomes and an X chromosome (22 + X) and the other type with 22 autosomes and a Y chromosome (22 + Y).
- Thus, half of the gametes will carry the 22 + X chromosome complement.
Additional Information
- Meiosis is a type of cell division that reduces the chromosome number by half, resulting in the production of gametes (sperm and egg cells).
- In humans, meiosis occurs in the testes for males and ovaries for females.
- Each gamete produced by meiosis contains 23 chromosomes, which is half the number of chromosomes found in somatic cells.
- Fertilization restores the diploid number of chromosomes (46) when a sperm and an egg combine.
- Understanding the chromosome complement is crucial for studying genetic inheritance and disorders.
