I guess what anon above meant, and that is if I remember biology class correctly, that female eggs are produced altogether at one time (I forgot when, could be birth, could be puberty) and there is a limited supply whereas the male sperm can be produced at really any time.
I guess the reason is that since the egg already exists long before the conception takes place, it would then store less memory.
genetic memory =/= dna

dammit, I´m the op and I still like my idea -.-
