True or False: Write TRUE if the statement is correct and write FALSE if the statement has incorrect information. If the statement is FALSE, identify the incorrect information and provide further  explanations, complete solutions, and examples to support your answer. 

7. Bingbong and Bebang visits a genetic counselor because they are worried about having a child  with Sickle Cell Anemia. The condition is inherited as an autosomal recessive trait, and  Bongbong's sibling Blengbong died of it. Bingbong's parents' offspring had a 25% chance of being  affected, a 50% chance of being carriers, and a 25% chance of being non-carriers. Because  Bingbong did not die to Sickle Cell Anemia, so he falls into the category of non-carriers.

If both of John's parents are heterozygous for sickle cell anemia and Sarah's parents are AA and Aa what are the chances that John and Sarah's child will have Sickle Cell Anemia? (Sickle Cell Anemia is an autosomal recessive disease)

Sickle cell anemia and albinism are both recessive traits inhumans. Imagine that a couple, already pregnant with twins, hasjust learned that they are both heterozygous for both of thesetraits. As the couple's genetic counselor, the couple asks you thefollowing questions about how their carrier status will affecttheir offspring.

1.

If the couple has fraternal twins, what is the probability thatboth children will be unaffected by both conditions?

2.

If the couple has fraternal twins, what is the probability thatboth of the couple's children will have both sickle cell anemia andalbinism?

3.What is the probability that one of the fraternal twins is acarrier of either, but not both, of the conditions?
(Hint: You will need to use both the product law and the sum law toanswer this question.)

4.

If the couple has fraternal twins, what is the probability ofhaving two phenotypically normal children, one being a carrier ofonly the sickle cell anemia recessive allele, and the other being acarrier of only the recessive allele for albinism?
(Hint: You will need to use both the product law and the sum law toanswer this question.)

1. Two persons with the sickle cell trait marry and want to have children, but concerned about them having sickle cell anemia. What is the probability of sickle cell anemia in their children? What proportion of their children would you expect to be carriers?

2. If a person with the sickle cell trait marries a person with a normal hemoglobin, what is the probability they will have a child with sickle cell anemia? What proportion of their children would you expect to be carriers?
