The human male determines the sexof his offspring.How is this so?

Answer 1

Sex is determined by a pair of chromosomes, X and Y. There is a pair in each cell of the human body. Females have 2 X chromosomes in each cell, and males have one X chromosome and one Y chromosome.

Sex cells, egg and sperm, called "gametes," don't have chromosome pairs. they only have 23 chromosomes whereas normal cells have 23 pairs of each type of chromosome or 46. Each gamete has only one of the (X or Y) type, and is formed by division of normal 46-chromosome cells. Because women have only X chromosomes, all their gametes have one X chromosome. But in males, half the gametes end up with an X chromosome, and half have a Y chromosome. There are so many male gametes that when they get to the female gamete, the egg, the odds are about 50/50 that the egg will be fertillized by a sperm with an X chromosome or a Y chromosome. This produces a "zygote" with either a pair of X's (female) or an X and a Y (male) which then divides and starts developing into a new organism.

This alternative explanation is ONLY A JOKE: It's a big secret, but actually when the women are sleeping men sneak downstairs, invoke the ancient gods and perform the sacred choosing ceremony by flipping a coin.

Answer 2

Males have the sex chromosomes XY while females XX, so when gamets are formed, each gamet will be (X)(Y) <--males
and (X)(X)<--females.

when you crosslink each gamet (male to female of course), you will get (XX)(XY)(XX)(XY)

as only the male carry the Y chromosome, he will decide his offspring's sex.

Answer 3

if its long, it will be a boy...
if its short it will be a girl....

Well, my friend told me... ( for some reason I doubt her)...lol
