A member asked:

Is it possible to have a yy baby if there's some chromosomal anomalies?

A doctor has provided 1 answer

Never been one: A baby gets a sex chromosome from each parent. Those fetuses that make it to delivery may have a single deletion (xo-turner, or doubled up (xxy or xyy), but since one sex chromosome is in the egg to begin with, an x, you're not going to see a yy. (unless you figure how to get a male pregnant.).

Dr Friedlander and another doctor agreed
