Assignment IX.6 Codominance New.

Document Content and Description Below

1. Write the genotype for each person based on the description: a. Homozygous for the “B” allele IBIB b. Heterozygous for the “A” allele IAIA c. Type O ii d. Type “A” and had a type �... �O” parent IAi e. Type “AB” IAIB f. Blood can be donated to anybody ii g. Can only get blood from a type “O” donor ii 2. Pretend that Brad Pitt is homozygous for the type B allele, and Angelina Jolie is type “O.” What are all the possible blood types of their baby? IBIB or IBi or ii 3. Draw a Punnett square showing all the possible blood types for the offspring produced by a type “O” mother and an a Type “AB” father O O A AO AO B BO BO 4. Mrs. Clink is type “A” and Mr. Clink is type “O.” They have three children named Matthew, Mark, and Luke. Mark is type “O,” Matthew is type “A,” and Luke is type “AB.” Based on this information: a. Mr. Clink must have the genotype ii b. Mrs. Clink must have the genotype IAIA because Matthew has blood type A c. Luke cannot be the child of these parents because neither parent has the allele B. 5. Two parents think their baby was switched at the hospital. Its 1968, so DNA fingerprinting technology does not exist yet. The mother has blood type “O,” the father has blood type “AB,” and the baby has blood type “B.” a. Mother’s genotype: ii b. Father’s genotype: IAIB c. Baby’s genotype: IAi or IBi d. Punnett square showing all possible genotypes for children produced by this couple IA IAi IAi IB IBi IBi e. Was the baby switched? No 6. Two other parents think their baby was switched at the hospital. The mother has blood type “A,” the father has blood type “B,” and the baby has blood type “AB.” a. Mother’s genotype: IAIA or IAi b. Father’s genotype: IBIB or IBi c. Baby’s genotype: IAIB d. Punnett square that shows the baby’s genotype as a possibility: [Show More]
