4. A female recently gave birth while in captivity; however, the paternity of the infant is unclear. Scientists tested the DNA from two male cheetahs, along with the female and offspring. The resulting electrophoresis gel is shown. Based on the gel electrophoresis results, what can be concluded about the paternity of the offspring? How do you know? Female Infant Male 1 5 Male 2

7. The Case of the Suspected Father: Blood typing is often used as evidence in paternity cases in courts, but it cannot be used to convict a man, only exonerate him (show that he is not the father!). In a series of disputed paternity cases, the mother and child each had the blood types listed in the table below. For each, indicate the blood types (phenotypes!) which, if found, would exonerate (free) an accused man. Mother's Phenotype Possible Genotypes for Child's Phenotype Possible Genotypes for Child Man exonerated if he has these phenotype(s) Mother A AB АВ A B A 8.
