Hahahahaha! That’s the funniest thing I’ve heard in years!
I didn’t know the Hebrews used the Greek alphabet before the Greeks even invented theirs.
Has nothing to do with the “alphabet”, chromosomes have a shape, and when they were finally seen, they looked like a pair of X’s, except in the male, one “leg” (or rib) was “missing”.
You can laugh all you want, but you should look in the mirror while doing it.
