Summary Introduction
Introduction:
Hemophilia is a genetic disorder in which the clotting of blood after a wound does not occur easily and properly and coagulation of blood takes time. The improper blood clotting can lead to excessive bleeding and infections over time and hence the death of an individual. This disease is also known as the royal disease as Queen Victoria was believed to have been a carrier of the disease.

C. What is the likelihood that II.3 will have a child that is a carrier?
d.
What is the likelihood that II.2 has three affected children?
Hemophilia is a disease caused by a gene found on the X
chromosome. Therefore, it is referred to as a sex-linked disease.
The recessive allele causes the disease. A man with hemophilia
(xhy) marries a woman who is homozygous dominant (XHXH.
A. Illustrate using a Punnett square the probability that their children
will have the disease.
B. Will any of their children have the disease?
C. Predict the probabilities of their children having the disease.
A man who is a carrier for cystic fibrosis marries a woman who is a carrier for cystic fibrosis. Respond to the question based upon this scenario.
What is the percentage probability that they will have a child who is a carrier?
a. 50%
b. 100%
c. 75%
d. 25%
