- A man with thalassemia minor marries a normal woman. What phenotypic ratios of thalassemia-affected children might these parents expect?Hemochromatosis is an inherited disease caused by a recessive allele. If a woman and her husband, who are both carriers, have three children,what is the probability of each of the following? (a) All three children are of normal phenotype. (b) One or more of the three children have the disease. (c) All three children have the disease. (d) At least one child is phenotypically normal.Clara has polydactyly, an autosomal dominant that is 80% penetrant. Clara inherited her polydactyly from her mother, her father had no polydactyly in his family. She has an extra toe on her left foot. Her husband Ralph has no polydactyly in his family. A) What is the chance that Clara will have a child that will inherit polydactyly? B) What is the chance that the child will express polydactyly. You can leave these as un-calculated equations.
- O. 2 Hemophilia A is an X-linked trait where blood clotting is affected due to a mutation in a clotting factor protein. Georgio has hemophilia and attends a support group where he meets Gbenga, who does not have the disease, but whose father has hemophilia. Her mother is not affected. A) If they marry, what percentage % of all their children will have hemophilia? % B) Georgio meets another woman, Maria, at the hemophilia support group. Maria also lacks the trait, but her mother has hemophilia while her father is unaffected. # 3 Would a Georgio-Maria mating provide a larger chance of having afflicted children compared to a Georgio-Gbenga mating? C) Show how you came up with your answer to B.

Only her mother carried the gene that caused her blood disorder. Only her father carried the gene that caused her blood disorder. If her parents have another child naturally, there is a 100% chance that the second child will be diagnosed with beta-thalassemia major. If her parents have another child naturally, there is a 25% chance that the second child will be diagnosed with beta-thalassemia major.Suppose a woman who is a carrier of sickle-cell trait (making her a heterozygote) has children with a man who is totally healthy and does not carry the gene for sickle-cell trait at all. Which one of the following is true about their potential children? (Draw a Punnett square on scratch paper if it helps you.) A) None of their children will have sickle-cell disease. B) All of their children will have sickle-cell disease. C) All of the couple's children would be heterozygous carriers like the mother.

Would any of the children show symptoms of the disease?One form of the bleeding disorder known as von Willebrand disease is an autosomal recessive disease.

Therefore, heterozygous (Cc) carriers do not display symptoms. Two parents who are carriers plan to start a family and you are a genetic counselor helping to advise them about their chances of having children affected by CF. a) Suppose the couple has 4 children, each one year apart. What is the probability that all 4 children will inherit CF? b) What is the probability that any 3 of their 4 children will not inherit CF, but 1 will be affected? c) What is the probability that their first child will not inherit CF, but the younger 3 children will inherit CF?Ronnie is convinced that baby Charlotte must be his daughter. He has heard about something called the “Bombay blood type”, and he is convinced that this phenomenon could explain how he could be Charlotte’s father. Please explain the Bombay blood type and its implications in this SPECIFIC situation, including (i) how it arises and (ii) genes involved, (iii) who would have the Bombay blood type in this scenario, and (iv) could Ronnie be Charlotte’s father, if this was present? Also (v) how could you determine whether the appropriate person actually had the Bombay blood type? Please LABEL the parts of your answer (i), (ii), (iii), (iv), and (v).
