How Many Chromosomes?

Pretty Pairs of Chromosomes

Oddly enough, I’ve discovered that lots of traffic comes to my blog because people want to know how many chromosomes men have. (It’s the fault of my Too Many X Chromosomes post, which actually has nothing to do with chromosomes themselves.)

So I thought I’d do a public service and make the answer available here. 🙂

Humans have 23 pairs of chromosomes in each cell (46 chromosomes total), whether we are female or male. The difference is that the 23rd chromosome pair is two Xs in a female, but an X and a Y in a male. This accounts for the difference in sex.

For more information, check out this lovely page on genetics.

Now that you have your answer, your duty is to go read my other posts and make me feel like you care. 😉
