UT EID: 18. You want to caloulate the probability that the crime scene sample in fact came from the matching suspect in order to avoid wrongful conviction. if the probability for a match at each SSR locus in t how many different, independently assorting SSR loci do you need to analyze to ensure that ho individuals have the same DNA fingerprint out of 7 billion hurnan population? B. 8 C. 9 10 19. What would happen if the transposase gene is mutated while the inverted repeats of a DNA transposon are wild-type? A. it would be defective in transposition even in the presence of a functional transposase B. It would move if a wild-type transposon is around C. It would move if a defective transposon that can make functional transposase is D. The transposase is not important for transposition. E. Both B and C around. 20. What would happen if the inverted repeats of a DNA transposon are mutated while the gene is wild-type? A It would be defective in transposition even in the presence of a functional transposase B. It would only move if a wild-type transposon is around. c. The transposase that gets made by it would allow mobillzation of other related transposons. D. The inverted repeats are not important for transposition. E. Both A and C 21. Which of these events cannot produce XXX individuals or mosaics? A. Nondisjunction of X chromosome during first meiotic division B. Nondisjunction of X chromosome during second meiotic division C. Mitotic nondisjunction of X chromosome D. Mitotic loss of X chromosome 22 Why is the incidence of Down syndrome very high among the offspring of a parent with Down syndrome? chromosome 21 cannot pair during meiosis l and will end up in roughly 50% of gametes. B. One chromosome 21 cannot pair during meiosis I and will end up in nearly all of the gametes. chromosomes 21 cannot pair during meiosis I and will end up in roughly 50% of gametes D. Two chromosomes 21 cannot pair during meiosis I and vill end up in nearly all of the gametes and are fertile. A triploid is produced by C. Two 23-25 Wld rainbow trout are diploids with 60 chromosomes fertilization of a diploid egg with a haploid sperm. hen mosome number X, for rainbow trout? cExplanation / Answer
18) The probability of a match at each SSR locus is 0.1. To ensure that now two individuals have the same fingerprint, the probability should be 1. So, in order to reach this probability, we need to have 10 independently assorting SSR loci (option D).
