What is the probability a female offspring developing hemophilia?
There is zero probability of the female offspring developing hemophilia.
What is the probability of a female offspring being a carrier for hemophilia?
There is a 25% percent probability that the female offspring will be a carrier of hemophilia
What is the probability of a male offspring developing hemophilia?
There is a 25% chance that the male offspring will develop hemophilia and a zero percent chance that the male will be a carrier of hemophilia.
What is the probability of a male offspring being a carrier developing hemophilia?
There is zero chance that the male will be a carrier of hemophilia.
What is the probability of any offspring developing hemophilia?
If there are two children, the probability of any offspring developing hemophilia it would be a 25% chance
Explain why only some offspring would develop the disease?
The reason why only some offspring would develop hemophilia is due Approximately 30% of cases of hemophilia are caused by a spontaneous mutation of the gene. In some cases, the mother is not a carrier of hemophilia, and the child is affected. This child may be the first in the family to have hemophilia and to carry the defective factor gene. In some cases, the genetic mutation occurs in the mother, and she finds out she is a carrier (through DNA testing) after she has a child with hemophilia. (www.hemophiliafed.org)
