Which chromosomes determine an individual's sex in humans?

Explanation:
Sex chromosomes are the part of the chromosome set that determines human sex. Humans have 23 pairs of chromosomes, including two sex chromosomes. The presence of a Y chromosome, and specifically the SRY gene on it, typically triggers male development; without a Y chromosome (XX), development follows the female pathway. Autosomes carry the vast majority of genes but do not determine sex. The genome is the complete collection of genetic material, and a karyotype is just a chart used to visualize which chromosomes are present; it doesn’t itself determine sex, though it can reveal the sex chromosomes.
