More likely you'd be "half-strong", too. We still don't know what killed off the rest of humanity, but if it was a disease that was human-specific and you weren't a carrier, it would die out. If you are and possess antibodies, you would pass these on and any offspring would inherit them.Plus, if I was the only person alive, what use is the sperm if the person who owned that sperm died too - obviously he wasn't strong enough to survive whatever killed all of man-kind. Yeah, sure, I would consist of part of the genes to the baby but what is the point of a half-strong baby?
The male does not determine whether the offspring is male or female. The female does, mostly, with some help from the male.Maybe I'm reading it wrong, but why wouldn't you be able to produce any males? It is the guy that determines whether we get a boy or not because only a male sperm carries the chomosome for determining if a baby is male or female. Females only carry the X chomosome....or that's what I thought.
Y-carrying sperm are very fast but the female reproductive tract is hostile to them and they die rapidly. They are also smaller and less robust, therefore you're going to have a dramatically-lower chance of producing a male if the sperm has been frozen. Timing is crucial to gender selection under normal circumstances... Our high male ratio is due to cultures that expect monogamy and cultures with extreme promiscuity, which result in higher frequencies of males than would naturally occur without such cultural pressures. Wars are fought because females are selfish.
