Question

How many chromosomes do you receive from your mother and your father?

Answer 1

We inherit a set of 23 chromosomes from our mothers and another set of 23 from our fathers. One of those pairs are the chromosomes that determine the biological sex of a child – girls have an XX pair and boys have an XY pair, with very rare exceptions in certain disorders.

Answer 2

Answer: Under normal conditions. Each cell in the human body has 23 pairs of chromosomes (46 in total). Half come from the mother and half from the father.

Explanation: Chromosomes are transferred in pairs.

Under normal conditions. Each cell in the human body has 23 pairs of chromosomes (46 in total). Half come from the mother and half from the father.

Two of these chromosomes (the X and the Y chromosome) determine one’s sex as male or female. They are called sex chromosomes:

• Females have 2 X chromosomes.

• Males have 1 X and 1 Y chromosome.

The mother gives an X chromosome to the child. The father may contribute either X or Y. The chromosome from the father determines if the baby is born male or female.

The remaining chromosomes are called autosomal chromosomes (22 pairs).

1 chromosome from mother+ 1 chromosome from father+ 22 pair autosomal chromosomes= 46
