why can't a mule reproduce with another mule since they both have 63 chromosome
Besides, great video
I watched the bird of paradise and they are beautiful.

[@EllieStanek]

I assume that the chromosome they are missing helps with the reproduction ability?

[@ecodank8325]

Living organisms with an odd number of chromosomes tend to be infertile, as they form non functional gametes

Human procreation is a hell of a thing.
