How many chromosomes per cell I m no expert so I ve not gone in and edited the following statement from the article but it seems odd to me as it flies in the face of everything I ve ever been taught about chromosomes each male cell contains only one X or one Y chromosome but not both This is true for nearly all male cells not just sperm cells that s from the section Whose genome was sequenced My understanding was that all male cells had 46 chromosomes except for sperm So am I ill informed or if not could someone correct that sentence to whatever it should have been
