The mother of a family with 10 children has blood typeRh+. She also has a very rare condition (elliptocytosis,phenotype E) that causes red blood cells to be oval rather than round in shape but that produces no adverseclinical effects. The father is Rh− (lacks the Rh+ antigen)and has normal red blood cells (phenotype e). The children are 1 Rh+ e, 4 Rh+ E, and 5 Rh− e. Information isavailable on the mother’s parents, who are Rh+ E andRh− e. One of the 10 children (who is Rh+ E) marriessomeone who is Rh+ e, and they have an Rh+ E child.a. Draw the pedigree of this whole family.b. Is the pedigree in agreement with the hypothesisthat the Rh+ allele is dominant and Rh− is recessive?c. What is the mechanism of transmission ofelliptocytosis?d. Could the genes governing the E and Rh phenotypesbe on the same chromosome? If so, estimate the mapdistance between them, and comment on your result
Hemophilia is an X-linked disease associated with the inability to produce specific proteins in the blood-clotting pathway. Shown above is a family pedigree tree in which family members afflicted with the disease are shown with filled-in squares (male) or circles (females). A couple is trying to determine the likelihood of passing on the disease to their future children (represented by the ? symbol above) because the hemophilia runs in the woman’s family 4.Assuming that the woman in the couple is a carrier, what is the probability that the couple’s first son will have hemophilia?
Sarah and George have been married for 6 years. They had a daughter 5 years ago and her blood type is AB. Sarah had complications during her birth and was transfused with three pints of type A blood. The couple recently welcomed a new baby boy to their family. He has the blood type O. What are Sarah and George’s genotypes? Select one: a. Sarah's Genotype George's Genotype IAIA ii b. Sarah's Genotype George's Genotype IAi IBi c. Sarah's Genotype George's Genotype IAi IBIB d. Sarah's Genotype George's Genotype IAIA IBi
A couple is planning a family, but since each has a brother having the sickle-cell disorder, they are worried that their kids might develop the disorder too. Neither of them nor their respective parents have the disorder. Which of the following will be your smartest advice as a genetic counsellor? One of four of their children can be expected to have sickle cell. It is possible that none of their kids will have the disorder, but tests should be carried out on both of them to confirm. All of their children will have sickle-cell disorder. There is no chance of any of their kids having sickle cell.
Rh factor is a protein that can be found on the surface of red blood cells. If your phenotype is Rh+ you have this protein on your red blood cells. If your phenotype is Rh-, then you do not have this protein on your red blood cells. Rh factor follows simple Mendelian genetics, meaning if you are Rh positive you can have the genotype Rh+Rh+ or Rh+Rh-. If Ruby's genotype is IBiRh-Rh-, and Sam's genotype is IAIARh+Rh-, what is the probability that their baby will be type AB+?
A) A woman with type O blood is expecting a child. Her husband is type A and her husband's parents both had type AB blood. What will be their child’s blood type? 2. A)A woman with type O blood is expecting a child. Her husband is type A and her husband's parents both had type AB blood. What will be their child’s blood type? B) A couple has one child with type AB blood. If one parent is heterozygous for blood type A and the other parent is homozygous for their blood type, what are the chances of their future children having: Type A blood? Type B blood? Type AB blood? O blood?
dominant-therefore someone with AB genotype has AB phenotype. You can see both because they are codominant) i) What are the possible genotypes for someone with A blood type? ii) What about B blood type? iii) Let's assume that an person by the name of Dustin Beilber (this name sounds really familiar for some reason) is taken to trial in a paternity suit by a woman claiming that he is the father of her child. He claims he is not the father. At the trial, an expert witness reveals the blood types of all three: Dustin's blood type – B Mother's blood type – A Child's blood type – O Based on these data, is it possible that Dustin is the father of this child? (To put this in terms of the scientific method, you are trying to disprove the hypothesis that Dustin is the father). If you can't disprove this, it doesn't mean that he is the father, it simply means that you cannot reject the hypothesis). Explain your answer.
Sickle cell anemia causes hemoglobin, the oxygen - carrying molecule of red blood cells, to be misshapen resulting in disease. "H" is the normal hemoglobin allele and "h" is the allele for sickle - cell shaped hemoglobin. In order to get the disease, a person must have a recessive genotype (hh). Two people with normal red blood cells are carriers of the gene - they have m genotypes Hh. Questions: a. What are the possible genotypes of the eggs the woman can produce? b. What are the possible genotypes of the sperm the man can produce? c. What is the genotypic ration for the offspring? d. What is the phenotype ratio for the offspring? e. What is the couple's chance of having a child a sickle cell anemia?

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.
Two couples had babies on the same hospital on the same day. Couple # 1 had a baby girl, Denise who has a blood type A+. Denise’s father is B+ and Her Mother is blood Type A-. Couple #2 had twins a boy Mark and a girl Ana. The Mother of the twins is B- and the father is A+. The twins’ grandparents on the paternal side are AA+ and AB-; The baby boy Mark is AB- and Ana is 0+. The Mother of Couple # 2 is convinced that the girls were mixed- up and they received the wrong baby girl. Knowing that you are an expert on bloody types and Mendelian genetics that have reached you out for help. Please solve the problem showing all possible evidence
