Textbook Question
Chapter 3, Problem 31P
The following table shows the responses of blood samples from the individuals in the pedigree to anti-A and anti-B sera. A plus (+) in the anti-A row indicates that the red blood cells of that individual were clumped by anti-A serum and therefore the individual made A antigens, and a minus (−) indicates no clumping. The same notation is used to describe the test for the B antigens.
| a. | Deduce the blood type of each individual from the data in the table. |
| b. | Assign genotypes for the blood groups as accurately as you can from these data, explaining the pattern of inheritance shown in the pedigree. Assume that all genetic relationships are as presented in the pedigree (that is, there are no cases of false paternity). |

- You're doing a blood typing test, and you know that the blood type you're testing should be A+. However, the test results keep coming up as A-. What might have went wrong in the experiment.arrow_forwardA RFLP is discovered that is linked to the gene for Duchenne’s muscular dystrophy (DMD). DMD is an X-linked, recessive trait. The RFLP is 2 map units from the gene for DMD. Consider the following pedigree and Southern blot using a probe that hybridizes to the RFLP. Which band/s is/are associated with DMD? What is the genotype for individuals 3 and 4? (Remember, this is an X linked disease, so use X’s and Y’s to denote). Individual 9 married a man who does NOT have muscular dystrophy, and she is pregnant. DMD is an X-linked trait. What is the probability for their child to have DMD? An amniocentesis is performed and it is determined that 9’s child in utero has only a 10 kb band that hybridizes to the same probe used above. What can you say about the child now?arrow_forwardA dihybrid test cross is made between the genes C and D with the following results:arrow_forward
- α-thalassemia is another blood disorder in which abnormal hemoglobin molecules are formed, leading to anemia. One mutant allele known to cause α-thalassemia occurs in α-hemoglobin and is called Constant Spring. Normal α-hemoglobin is 141 amino acids long, while the Constant Spring protein is 172 amino acids long. Include answers to both A and B in your response. A maximum of 2 sentences per part. A) Explain how a frameshift mutation in the coding region of α-hemoglobin could result in the Constant Spring protein. B) Explain how a single base-substitution mutation in the coding region of α-hemoglobin could result in the Constant Spring protein.arrow_forwardHOW DO I SOLVE THIS STEP BY STEP: Recent studies suggest that having the A blood type increases the risk of serious complications for patients suffering from COVID-19.

- Several genes in humans in addition to the ABO gene () give rise to recognizable antigens on the surface of the red blood cells. The Rh marker is determined by positive (R) and negative alleles () of gene R, where R is completely dominant to r. The presence of M and N surface proteins are controlled by two codominant alleles of gene L (LM and LM. For each mother-child pair, choose the father of the child from among the males in the right column. (Assume that all mothers and fathers are HH; there is no involvement of the Bombay phenotype.) Paternal genotypes maybe used once, more than once, or not at all. Each mother-child pair matches with one or more than one paternal genotype. Maternal phenotype: Child phenotype: Paternal genotype: Reset A, M, Rh(neg) O, M, Rh(pos) B, N, Rh(neg) O, N, Rh(pos) O, M, Rh(neg) A, MN, Rh(pos) A, N, Rh(pos) AB, MN, Rh(pos) B, N, Rh(pos) A, MN, Rh(neg) Genotypes of possible fathers AiLMLN rr BiLMLN RR ii LNLN rr ii LMLM rr AALMLN RRarrow_forwardThe shape of radishes may be long, round, or oval.
