Sickle cell anemia is a genetic blood disorder where red blood cells lose their flexibility and assume an abnormal, rigid, sickle shape, which results in a risk of various complications. If both parents are carriers of the disease, then a child has a 25% chance of having the disease, 50% chance of being a carrier, and 25% chance of neither having the disease nor being a carrier. If two parents who are carriers of the disease have 3 children, what is the probability that (a) two will have the disease? (b) none will have the disease? (c) at least one will neither have the disease nor be a carrier? (d) the first child with the disease will the be 3rd child?

Q: Sickle cell anemia is a genetic blood disorder where red blood cells lose their flexibilityand assume an abnormal, rigid, sickle shape, which results in a risk of variouscomplications.

If two parents who are carriers of the disease have 3 children,what is the probability that (a) two will have the disease (b) none will have the disease (c)at least one will neither have the disease nor be a carrier (d) the first child with the diseasewill be the 3rd child Step By Step SolutionStep 1 of 5:P(having sickle cell anemia)=P(D)=0.25P(being a carrier)=P(C)=0.5P(not having disease nor carrier)=P(N)=0.25
