Hemophilia is a typical example of Sex-Linked Inheritance. If the man is hemophilic and marries a homozygous normal woman. What will be the genotype of the female child?
Hemophilia is due to a sex-linked gene. It is recessive and found on the X chromosome. A woman who is a carrier for hemophilia marries a normal man. What will be the possible phenotypes of their children? (use the letter “H”)
Two normal parents have a child with cyatic fibrosis. Would this be an autosomal dominant or autosomal recessive disorder? What is the chance that their next child will have cystic fibrosis?
A form of hemophilia is caused by a sex-linked (X-linked) recessive gene. A phenotypically normal woman whose father had hemophilia marries a man who suffers with hemophilia. What is the probability that their first daughter will have hemophilia?
What is Down's syndrome? Give its symptoms and cause. Why is it that the chances of having a child with Down's syndrome increases if the age of the mother exceeds forty years?

Fred, a male, is affected with Lalaphobia. Fred's father is also affected with Lalaphobia; but his mother is unaffected. Fred marries Ginger (a female), who is unaffected, and they have four children: An affected son An unaffected son An affected daughter An unaffected daughter Ginger is pregnant with a fifth child, a son. What is the probability that this son will be affected by Lalaphobia? Assume Lalaphobia is a rare disease. Your answer should be a whole number between 0 and 100. For example, if you enter 33, it means you think there is 33% chance that the son will be affected by Lalaphobia.
