The father does. He carries both the x and y chromosomes and one or the other will determine the sex of the baby.
The thing is that if the chromosomes of mother dominates the chromosomes of father then they will have a girl n in the other fathers dominating case we will have a boy its a long thing how chromosomes dominate each other but they do .
Gender can also be influenced by outside factors, e.g. water supply. Liverpool changed water supply, and the proportion of boy babies increased.
Yes it is from the father that this comes but not at the level of a single gene. The genes that determine sex are to be found on the sex chromosomes, of which every person has two. They come in two types X and Y. Woman have an XX pair and Men have an XY pair. Thus as you can see the Y chromosome is that which makes the difference and this comes from the man.
Actually it is a sex chromosome. The male has two, a Y and an X. The female has two X chromosomes. The father gives either an X or a Y. The mother only one X. The child will have XY (a boy) or XX (a girl). So the father determines the sex of the baby.
The male/dad. The male/dad has two cells, if he passes on the X cell it's a girl. If he passes on the Y cell it's a boy. The female/mum has two X cells.
If a baby gets one X and one Y chromosome, it is a boy. If it gets two X chromosomes, it is a girl.
yes particular one's do which are the xy chromasones
A boy is male.
Everybody has 23 pairs of chromosomes, half they get from their mother and half from their father. The 23rd chromosome you have contains the information of what sex you are. If you are a girl you will have a X chromosome from your mother and and X chromosome from you father. If you are a boy it means you will have a X chromosome from your mother and a Y chromosome from your father. When a sperm cell fertilises an egg the sperm will either be carrying the X chromosome from the male or a Y. If the sperm is carrying a X it will pair with the X chromosome from the mother making the baby a girl. If the sperm is carrying a Y chromosome it will pair with the X chromosome from the mother making the baby a boy! This means it is all down to the father whether the baby is a boy or a girl.
you look under and if it has a stick that means a boy and if it has a hole that means its a girl
The chromosomes in the sperm determine whether the baby is going to be a girl or boy.
You cannot decide your baby's gender. But you can do things to help improve your chances in getting a female or a male baby.
