So I read this article recently about Harrison Ford and how some people have spotted him wearing a "manzeer" recently. They explain why males have nipples and breasts. Something that caught my eye though was someone's comment:

"A male can only create another male. Females can only create another female. Every man on this earth shares the same Y chromosome that was passed down by every man before him. The only thing that happens inside of a female is incubation."
"In all actuality, people come from the male and not the female. It depends on which sperm makes it in the egg. The sperm with the XX chromosomes, or the sperm with the XY chromosome. The sperm head contains all of the information with-in it."

Eh? This person makes it sound like eggs are just blank vessels with no DNA whatsoever and all DNA comes from males. As far as I know people get their DNA 50/50 from the mother and from the father. People trace ancestry through mitochondrial DNA which is only passed down through the mother's side. This can be traced way way back. There isn't anything similar on the male's side that I have heard of. If anything this person has things backwards. Do I detect male chauvinism on their part? I tell you this person just has to be wrong!
