Chapter E, Problem 7P
The results shown are from a DNA test for four genes used in a paternity identification case. DNA for the mother (M) and her child (C) are shown along with DNA from two possible fathers,
a. In the “C” column, label the DNA bands contributed by the mother with “M” and the DNA bands contributed by the father with “F.”
b. Based on the exclusion principle, is either man excluded as the possible father? Explain.
c. What can you conclude based on the DNA results available?

(closed square, controlled mating, diamond, hexagon, open circle, open square, pedigree, two horizontal bars) Due to the limitations of studying humans investigations rely on pedigree analysis. The symbol used in a pedigree for an affected male is a closed square. The symbol for an unaffected female is an open circle. An individual of indeterminate sex is represented by a diamond in a pedigree. In a pedigree a consanguineous mating is diagrammed as_______between a male and a female.arrow_forward
- In 1967, a couple accused a hospital of switching their baby with another. DNA interpretation did not exist at this time so the hospital traced the blood types of the family in order to determine if a mistake was made. The mother had Type A blood, the father had Type AB blood, and the baby had Type O blood. Use the Punnett square to defend your answer to the following question: Did the hospital make a mistake and switch the baby? ____________arrow_forward(healthy) Tom and his wife Julie are both carriers for cystic fibrosis, an autosomal recessive disease. Draw a Punnett square and be sure to include the following information for f credit: 1. Place the parents alleles at the top and on the left side. 2. Write in the allele crosses inside the Punnett squares. 3. Write out the genotypes probabilities for an offspring. 4. Write out the phenotype probabilities for an offspring. E 5. What is the chance that Tom and Julie's first child will have cystic fibrosis?arrow_forwardIn a paternity case a single mother claimed that a certain man was the father of her baby. The man denied it claiming that her current boyfriend was the father. The court ordered a blood test (cheaper than dna testing) to see if he could be ruled out as the father. The mother is type O and the baby was type O the man was type AB. What is the possible genotype of the biological father? A. Heterozygous Type A B. Homozygous Type A C.
