do all men produce 50/50 of each sperm giving chance of girl or boy (mixed family) and
do some men produce more x sperm lets say 79% x 21% y giving higher chance of a girl and
do some men produce more y sperm more chance of boys.
is this why some have male dominate families or girl dominate families? do you think all mens sperm is 50/50 or varies?
