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.

What are the X and Y chromosomes called?
The X and Y chromosomes are called the "Sex Chromosomes". Both the X and Y chromosome are part of the "sex-determining system" that helps determine the sex characteristics in humans. In the system, females have two X chromosomes (XX) while males have an X and a Y chromosome (XY).
What is a child with X and Y chromosomes?
A child with X and Y chromosomes typically identifies as male. This combination of chromosomes determines male biological development, including physical traits such as testes and the production of testosterone.
Do animals have both X and Y chromosomes?
No, animals do not have both X and Y chromosomes. In most animals, males have XY chromosomes and females have XX chromosomes.

The chromosomes that determine an individual's biological sex are called the X and Y chromosomes.
Sex-linked genes are usually found in which chromosome?
Sex linked genes are located on the sex chromosomes.

What are the chromosomes that are not X or Y?
All chromosomes that are not either X or Y are called autosomes.

The human X and Y Chromosomes are what?
The human X and Y chromosomes are:both present in every somatic cell of males and females.approximately equal in size.almost entirely homologous, despite their different names.called "sex chromosomes" because they determine an individual's sex.
What are the chromosomes that determine the sex of the offspring?
the X and Y chromosomes
What is the chromosome that represents the sex chromosome?
The sex chromosomes are represented by X and Y chromosomes. In humans, females have two X chromosomes (XX), while males have one X and one Y chromosome (XY). The presence of the Y chromosome determines male physical characteristics.
Men have one of y?
The y chromosome. The chromosome pair that determine sex (gender) can have x and y chromosomes; men have one X and one Y chromosome, women have to X chromosomes.
What do X and Y chromosomes affect?
X and Y chromosoms determine whether or not an offspring is a male or female. Chromosomes come in pairs. Boys have an X and a Y chromosome pair; girls have an X and an X chromosome pair.
What does an x and y chromosome identify?
In the cytological terminology x and y chromosomes are identified as sex chromosomes. In human being these chromosomes are responsible for determination of sex in the offspring.
