What role do the chromosomes that determine sex play in the development of an individual's gender identity?

The chromosomes that determine sex, specifically the presence of XX or XY chromosomes, play a significant role in the development of an individual's biological sex. However, gender identity is a complex interplay of biological, psychological, and social factors that may not always align with one's chromosomal makeup. Gender identity is a deeply personal sense of being male, female, a blend of both, or neither, and can be influenced by a variety of factors beyond just chromosomes.
