- In the Bombay phenotype, a homozygous recessive individual hh appears to have blood type O because she is unable to produce the H substance, which is required to make the A or B blood-type antigens. HH or Hh individuals normally produce H substance. What is the probability that a child will test as type AB blood from parents with the following genotypes? IAIO Hh X IBIA hh 3/16 1/8 1/4 3/4 1/2A woman who has blood type A positive has a daughter who is type O positive and a son who is type B negative. Rh positive is a trait that shows simple dominance over Rh negative and is designated by the alleles R and r, respectively. A third gene for the MN blood group has codominant alleles M and N. If both children are of blood type M in addition to their ABO blood type, list all of the possible parental phenotypes for the ABO, MN and Rh traits.A woman who has blood type A positive has a daughter who is type O positive and a son who is type B negative. Rh positive is a trait that shows simple dominance over Rh negative and is designated by the alleles R and r, respectively. A third gene for the MN blood group has co dominant alleles M and N. If both children are of blood type M in addition to their ABO blood type, list all of the possible parental phenotypes for the ABO, MN and Rh traits.

IAIO Hh X IBIO Hh 1/4 3/4 3/16 1/2 7/16The 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 resultA woman homozygous for normal height, with freckles, almond-shaped eyes, small nose, and Type A blood, has a Type O mother with no freckles and a type AB father with round eyes. She is engaged to a man with achondroplasia, round eyes and medium sized nose. Unlike his father, hismother is of normal height. Both his parents have Type O blood but nobody from both sides of his family has or had freckles. a. Write the COMPLETE genotypes of the man and the woman. Clearly indicate which genotype belongs to whom. b. Based on their genotypes, what is the probability that they will have: b.1 a child with Achondroplasia? b.2 a child of normal height? b.3 a child with type AB blood? b.4 a daughter with round eyes, freckles, and medium sized nose? b.5 a son with almond eyes, no freckles, and small nose?b.6 a daughter with same genotype as the woman? b.7 a son with same genotype as the man?
- A child has a blood type of “B positive”. This child is known to be a heterozygote at the ABO blood type gene and also a heterozygote at the Rh blood type gene.

The trait is X-linked. A female hemophiliac has a child with a man who is not a hemophiliac. What is the probability that this couple's child is a hemophiliac and what is the child's gender? Your response must include a Punnett square with correct nomenclature.A man who has type O blood has a child with a woman who has type A blood. The woman's mother has type AB blood and her father, type B. What is the probability that the child has type A blood? O 0% O 75% O 100% 50% O 25%
- In a paternity suit, a woman with type O blood claims that a man with type AB blood is the father of her type O baby. List the genetypes of the mom, man, and baby. Can the woman prove he is the father or can he is not? Why or why not? If the accused man was type A insyead of type AB, what would be his possible genotypes? Could the woman prove he is the father? Can the man prove he is not the father? Why or why not?This problem refers to the MN and ABO loci mentioned in class. It also refers to the Rh locus, which is responsible for the positive/negative part of the blood type. The Rh+ allele is dominant to the Rh- allele at this locus. Select all couples who could be the parents of a child with phenotype N, AB- based on the phenotypes at these three loci If none of these couples could be the parents of this child, select "None of These. Select one or more: Mother Type MN, B+ and Father Type N. O+ Ob Mother Type MN, AB- and Father Type M, O- Mother Type M, A+ and Father Type N, B- O d. None of These Mother Type MN, O+ and Father Type MN,A-List the 6 possible genotypes of the four blood types. Identify the parentalgenotypes that could produce children with blood type AO.
