Question

If the father has hemophilia and the mother is a carrier for the disease,

what would be the likelihood of them having a child with hemophilia?
Create a punnett square using the table tool to figure out the
possibility.

Answer 1

I can't figure it out sorrrrrrry

Answer 2

There is a 50% chance that the couple's child will have hemophilia.

What is hemophilia?

• It is a genetic disorder.
• It is a problem with blood clotting.

Hemophilia is only expressed in males who have an X chromosome, inherited from the mother, containing the gene for the disease, and the Y chromosome, inherited from the father. If the X chromosome does not have the disease gene, this man will not develop the disease.

In women, hemophilia will only be expressed if both X chromosomes (one inherited from the father and the other inherited from the mother) have the gene for the disease. If only one of these chromosomes contains the gene, the woman will not express the disease but will carry the gene and pass it on to her children.

In the case of the couple shown above, we can make the following punnet square:

XH Xh

-------------------------------------------------

Y XHY XhY

If we consider that the XhY gene is the gene that carries hemophilia, we can consider that the couple's child will have a 50% chance of inheriting hemophilia.
