a.
Summary Introduction
To determine: The genotypes of the parent when all their children have Rh+ blood group.
Introduction: There are two types of Rh blood groups: Rh+ (have Rh antigen) and Rh- (do not have Rh antigen). Rh factor is a point of concern when the mother has Rh- and fetus has Rh+ blood group. This condition can cause hemolytic disease of newborn baby (HDN).

Summary Introduction
To determine: Whether the parents in the given case should be concerned about the risk of the occurrence of hemolytic disease to the newborn.
Introduction: There are two types of Rh blood groups: Rh+ (have Rh antigen) and Rh- (do not have Rh antigen). Rh factor is a point of concern when the mother has Rh- and fetus has Rh+ blood group. This condition can cause hemolytic disease of newborn baby (HDN).

A child with the "B positive” blood type is known to be a heterozygote at both the ABO blood type gene and also the Rh blood type gene. What is the genotype of this child at these two genes?
In blood groups, Rh positive blood is dominant (R) over the gene for Rh negative blood (r). What types of offspring could be expected for an Rh positive AB woman, (whose father was Rh negative), who marries a man with heterozygous A positive blood?
What would the offspring's blood type be if the mother is type O+ (she is homozygous for Rh factor) and the father is A- (he is homozygous for type A)? Hint: You have to do two Punnett squares. The two Punnett squares must be shown to get the full points. After doing the Punnett squares, write down the possibilities of the offspring’s blood type.

Include the solutionarrow_forwardRh factors are proteins that were first discovered in the blood of Rhesus Monkeys, but humans have them too. If you are Rh positive, it means that there are Rh type proteins in your blood. If you are Rh negative, there are no Rh type proteins in your blood. Positive is dominant over negative, so heterozygous individuals are Rh positive. Problems can arise when an Rh negative mother has a child who is Rh positive. Which of the statements will answer the following questions: Why does the mother's body attack her own baby in this situation? Why does the situation get worse for the second pregnancy? a. The mother's body sees the foreign proteins produced by her baby as a threat. She builds up antibodies against them. b. Her immune system attacks the baby, often resulting in a miscarriage. Immune suppressing drugs can be given to the mom, but then she's more likely to get sick because her body's germ fighting ability is diminished. c. The baby is delivered before the situation gets too…arrow_forward
- Woman who has blood type B positive has a daughter who is type O positive and a son who is type A negative. Rh positive is a trait that shows simple dominance over Rh negative.

She is currently pregnant and she would like to know what type of blood her baby will have. For discussion 7 please answer the following questions: What are the genotype and phenotype of Mrs. Rodriguez? What are the genotype and phenotype of Mr. Rodriguez, given that Mr. Rodriguez’s mother has O blood type and his father has A blood type? (use Punnett Square on your worksheet to find out the genotype of Mr. Rodriquez) What is the probability that Mrs. Rodriguez’s baby will have O blood type? A? B? AB? (use Punnett Square as your worksheet) Type O =______% Type A = _____ % Type B =______% Type AB =______%arrow_forwardA woman whose blood type is A- is planning on starting a family with a B+ blood type man. Which of the following is the most accurate advice that you could give to this couple based on their blood types? They should be concerned about hemolytic disease of the newborn for all of their pregnancies . Since the woman is Rh-, she produces anti-Rh antibodies. Since the man is Rh+, the fetus in all pregnancies with this man will also be Rh+. This means that the mom?s anti-Rh antibodies will destroy fetal RBCs every time that the woman gets pregnant, thus producing a dangerous anemia to all the fetuses from all pregnancies with this man. They should be concerned about hemolytic disease of the newborn. However, problems related to this condition seldom develop during a first pregnancy, because very few fetal cells enter the maternal bloodstream then, and thus the mother?s immune system is not stimulated to produce anti-Rh antibodies. However if a future pregnancy with the…arrow_forward

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?
