What determines if your having a boy?

Men determine the sex of a baby depending on whether their sperm is carrying an X or Y chromosome. An X chromosome combines with the mother's X chromosome to make a baby girl (XX) and a Y chromosome will combine with the mother's to make a boy (XY).

Research over hundreds of years has consistently found that boys naturally outnumber girls at birth. The speculation is that this is nature's way of countering the relatively high mortality rates of males, and creating more of a gender balance in the population.

What causes a baby to be a boy?

The mother's egg contains an X chromosome, and the father's sperm contains either an X or a Y chromosome. A baby who inherits the X chromosome from the father is a genetic female (two X chromosomes). A baby who inherits the Y chromosome from the father is a genetic male (one X and one Y chromosome).

Which gender has more genes?

Men and women have practically the same set of about 20,000 genes. The only physical difference in their genetic make up is in the sex chromosomes. Only males have a Y chromosome.

Who carries the gene for a boy?

When I tell patients there's about a 50/50 chance for either sex, I also tell them the father's genes determine the baby's sex since some of his sperm carries X chromosomes and some carries Y chromosomes. That's with the assumption, though, that the man's sperm carries equal numbers of X and Y chromosomes.

What genes are inherited from father only?

All men inherit a Y chromosome from their father, which means all traits that are only found on the Y chromosome come from dad, not mom. The Supporting Evidence: Y-linked traits follow a clear paternal lineage.


Who does the baby get the most genes from?

The egg and sperm each have one half of a set of chromosomes. The egg and sperm together give the baby the full set of chromosomes. So, half the baby's DNA comes from the mother and half comes from the father.

Sexual positions

Deep penetration, for example doggy style, means the male sperm that can swim faster start their race closer to the cervix and are more likely to reach the egg first, resulting in a boy. To try and conceive a girl, Shettles suggested avoiding deep penetration, favouring the missionary position.
