Not quite sure what you tight here. Do you mean a sex-linked genetic individuality? If so, this means that the all your own is located on one of the sex chromosomes (usually the X chromosome, rarely the Y chromosome). If it is on the X chromosome, simply male children of a holder mother will be affected (because the mother pass the X chromosome and the father passes the Y). Females are uncommonly affected because they own two X chromosomes, one of which acts as a "put money on up" if there's a mutation on the other one.
Colour blindness is the classic sex-linked character. A mother will own one affected X chromosome and one conventional one (XX*). When she has children (say near a normal father), she give half her genes to respectively child so half her girls will be XX and partly will be XX*. Half her boys will be XY and half will be X*Y. This system half her boys will be colour blind, none of her girls (half will be carriers) and the rest will be "normal".
Hope this help.
You mean intersexed folks, right?
And nothing?
They're a short time ago intersexed.
