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.

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.

- Draw the punnet square and explain the resultsarrow_forwardSeveral genes in humans in addition to the ABO gene(I) give rise to recognizable antigens on the surface ofred blood cells. The MN and Rh genes are two examples. The Rh locus can contain either a positive or anegative allele, with positive being dominant to negative. M and N are codominant alleles of the MN gene.The following chart shows several mothers and theirchildren. For each mother-child pair, choose the fatherof the child from among the males in the right column, assuming one child per male.Mother Child Malesa. O M Rh(pos) B MN Rh(neg) O M Rh(neg)b.

He had severe injuries including a compound fracture of his tibia and needed immediate surgery and a blood transfusion. Routine blood-group typing categorized him as O+ because his red blood cells showed no reaction with anti-A or anti-B antibodies. But cross-matching with the different bags of O blood in the blood bank showed cross-reactivity or incompatibility with them all. The blood-bank staff reported that the patient had a rare blood type called the Bombay blood group. His twin brother Nadeesh, who arrived at the emergency room within hours of the family being notified, donated the blood his brother needed. It was recommended that he and his brother wear medical alert bracelets in case they need emergency blood transfusions in a situation where thorough cross-matching is not possible. Which of the following is consistent with the Bombay phenotype? a. The Bombay phenotype results…arrow_forward
- A man of blood group A is being sued by a woman of blood group B for paternity. The women’s child is blood group O. A) Is this man the father of this child? Explain. B) If this man actually is the father of this child, specify the genotypes of both parents. C.) If it was impossible for this group A man to be the father of a type O child, regardless of the mother’s genotype, specify his genotype. D.) If a man was blood group AB, could he be the father of a group O child? Why/why not?arrow_forwardPlease answer this question.arrow_forwardPlease complete table 15.2 with diagrams that illustrate the appropriate components. Which blood cells are co dominant? Which are recessive? Complete a punnet square A based upon a cross between individuals with the following genotypes : AO & BO.arrow_forward
- a) What are all the possible genotypes of an individual with type A blood? (We are not considering Rh factor for these problems) b) Marge has type B blood and Homer has type A. What are all the possible blood types that their kids could have? c) Nikki has type AB blood. She is in a car accident and is critically injured. The hospital is out of all blood except type O. Can Nikki have a transfusion of type O blood? Explain your answer.arrow_forwardThe following data were presented to a court during a paternity suit: a) the infant is a universal donor for blood transfusion; b) the mother bears antibodies against the B antigen only; c) the alleged father is a universal recipient in blood transfusion. Answer too questions: - Can you identify the ABO genotype of the three individuals ? - Can the court draw any conclusions ?arrow_forwardHello, i understand the question, but i only need to know which option is right, no need for explanation. I mean jsut say which option, thanks in advance.arrow_forward
- y 301 Amelogenesis imperfecta is X-linked dominant. Affected XY individuals have extremely thin enamel on the teeth while XX carriers have grooved teeth from uneven deposition of enamel. If an unaffected XY individual were to produce children with a XX carrier partner, a. what would be the expected chance of a XY child being affected with the disease? b. what would be the expected chance of a XY child being affected with the disease?arrow_forwardIn humans, the genes for red-green color blindness (R = normal, r = color blind) and hemophilia A (H = normal, h = hemophilia) are both X-linked and only 3 map units apart. Suppose a woman has four sons, and two are color blind but have normal blood clotting and two have hemophilia but normal color vision. What is the probable genotype of the woman?

A1Α2 b) Genes A, B and C are on the same chromosome linked in cis (coupling) conformation. A is 23 cM from B, and B is 17 cM from C. The distance between A and C is 40 cM. The coefficient of coincidence is 0.75 for a trihybrid test cross. How many individuals with the genotype aaBbcc do you expect to see among the offspring of the cross if 1000 offspring are obtained? Please show your calculations and round your answer off to the nearest whole number.arrow_forward
