Small correction to the comment above - a sperm doesn't have two of anything --
just one each of chromosomes 1-22 plus an X or a Y. For a total of 23. So does
the egg, except it always has an X. When the two get together, you get 46 -- a
pair of 1-22 plus XX or XY, depending on what the sperm brings to the occasion.
Kudos to all - great site!
Cool site, but a sperm only contains one (for a boy) or two (for a girl) X
chromosomes, not 23...
The graphics really draw you in... Great work on this site!
I'll be bookmarking the site. Well done!
Amazing website!!! Nice work Utah!!
Yep, it's really cool!
