Hello, I am a student doing a research report and wondering if
someone could tell me the comparison between men and women chromesomes.
Your help would be greatly appreciated! Please e- mail me at

The chromosomes(with the exception of the sex chromosomes) are exactly alike.
The male has 2 different sex chromosomes(an X and a Y). The Y is one of the
smallest in our genome and it primarily determines male sexual development in
arly embryogenesis.
The X chromosome is very large and nearly metacentric(submetacentric) and
females normally have two. All normal females produce eggs with a single X,
and the male produces X-sperm and Y-sperm. X to X fertilizations produce
normal females usually and X and Y combinations are, for the most part, normal
males. So males usually determine the sex of the child.
