So I just happened upon the Wikipedia page for muntjacs (those cute deer with tusks), and saw that Indian muntjacs have a 2n of 6 for the female (wow, especially since another subspecies has 46!) and 7 for the male (confused?).
I know many insect sexes have different chromosome numbers, but I didn’t know it happened in mammals. I also didn’t know mammals could have an odd number of chromosomes. I was under the impression that to form gametes, you needed an even number- thus why mules and triploid bananas are sterile.
Am I wrong? What’s with that extra male chromosome? What do Indian muntjac gametes look like?
