Which chromosomes determine the sex of an individual?

Answer 1

There are two kinds of chromosomes the determine the sex of a child. The X and Y chromosomes. A male has an X an Y and a woman has an X and an X. When a man sperm meets with the unfertilized egg, half the DNA strand of a male(containing wither an x OR y chromosome) and half a DNA strand of a woman (containing ONLY a X chromosome) come together to determine the gender of the baby. As states above, xy=male. xx=female.
It is the chromosomes of the father that determines the gender of the child.

Answer 2

The chromosomes are called the X and Y chromosomes. If it are two XX then it is a girl if there are an XY then it is a boy. As a type of chromosome, they are referred to as the sex chromosomes.

Answer 3

This is true. Chromosomes exist in pairs; of our 23 pairs (or sets) of chromosomes, the sex-chromosome pair {I think Pair number 23} consists of 2 X(shaped) chromosomes in a Female and one X chromosome and one Y(shaped) chromosome in a Male.

Answer 4

The sex chromosomes are known as the X and Y chromosomes.

XX will lead to female development

XY will lead to male development

(There are other variations, but those are not normal)

Thus, it is ultimately the presence or absence of the Y chromosome that determines the sex of an individual.

Answer 5

The twenty third chromosome pair. XX-female XY-male
