Karyotypes

[foxgrrl]

People frequently ask me whether I have XX or XY [sex] chromosomes. I honestly don't know. I've never been tested. What chromosomes do you have? I mean they test everyone don't they? It sure seems like they tested everyone but me…

Actually, in birds, Lepidopterans, and other animals in which females are the heterogametic sex, the sex chromosomes are called W and Z instead of X and Y.

(Heterogametic meaning one individual having two different sex chromosomes, which in humans is XY. Homogametic = XX)
