Here's the breakdown:
* Body chromosomes (autosomes): These are the chromosomes that carry the genetic information for all the physical traits that make up a person, except for sex-related characteristics. Humans have 22 pairs of autosomes.
* Sex chromosomes: These chromosomes determine a person's biological sex. Humans have one pair of sex chromosomes:
* Females: XX
* Males: XY
So, while X and Y are chromosomes, they are not "body" chromosomes. They are specifically the sex chromosomes that help determine a person's biological sex.
