Abigayle is a carrier for hemophilia. her husband, claude, does not have the disorder. if abigayle and claude have children, which of the following statements will be true? 1. none of the children will have hemophilia. 2. there is a 100 percent chance that a boy will have hemophilia. 3. there is a 50 percent chance that a girl will be a carrier. 4. there is a 25 percent chance that a girl will have hemophilia.

The correct answer is - option 3.

Explanation:

Hemophilia is a recessive genetic sex linked disorder that is located on the X chromosome and only visible in the present in absence of normal allele of the hemophilia.

If there is normal x chromosome present in a female she will be carrier for the disease while if a male have faulty gene he will be affected. The punnete square is provide for this case.

In the given case, father has a normal X-chromosome. (XY) as he does not hemophilia and as Abigayle have only one faulty gene as she is carrier for the disorder.

A punnett square will explain all possible outcomes:

 X   YX   XX  XY   (healthy)x   Xx  xY     (carrier or has hemophilia)

Now examine the given statements:

There is a 50 percent chance that a girl will be a carrier.

   (given a girl, 25% out of 50%=50% she will be a carrier, so TRUE)
