Genetics Test Study Guide Answers Biology 1
cDNA. reverse transcriptase. Be able to interpret 4. What is CRISPR? What is a SNP?.
uses. general procedure. given a set of SNP's, find the one most likely associated with trait 6. State the Hardy-Weinberg Principle including the conditions that must be met. Define p, q, P, H, Q. Given a population and a trait showing incomplete or codominance, calculate allele and genotype frequencies. If AA=34, Aa=42 and aa=12, what are the allele and genotype frequencies.
(Answer P =.39, H=.48, Q=.14, p=.63, q=.38) 9. Give a population and a trait with complete dominance, calculate the allele and genotype frequencies. Tongue curling is dominant to not being able to curl tongue. If a population has 88 curlers and 44 non-curlers, what is the genotype and allele frequencies assuming Hardy-Weinberg equilibrium (Answer: Q=.333, q=.577, p=.423, P=.179. Given a population and a sex-linked trait, calculate genotype and allele frequencies.
If p=.99 and q=.01, what are the genotype frequencies for normal and color-blind. (Answer: Cy =.99, cy =.01, CC =.9801, Cc = 0.0198, cc =.0002) 11. Given information on a population, be able to calculate P,H,Q,p,q and whether the population is in Hardy-Weinberg Equilibrium e.g. A population of hypothetical insects has genotypes of AA=230, AB=560, and BB=102. Is this population in Hardy-Weinberg Equilibrium? (Answer: P = 0.26, H = 0.63, Q = 0.11, p =.575, q = 0.425, if HW then P = 0.33, H=.49 and Q =.18 so no. Given information on survival rates and/or relative fitness, be able to calculate the effect of natural selection on the population.
Assume in the population of insects above that the survival rate of AA individuals is 1.0, AB individuals is.9 and BB individuals are.2. What is q in the next generation? (Answer: q' = 0.36) 13.
Given information about mutation rates, calculate the allele frequency in the next generation. Assume the mutation rate from a normal allele to cystic fibrosis is 1x10^-5 and a small island population has an allele frequency of 1/10,000.
What are p and q in the next generation? (Answer: p'=.99989, q' =.00011) 14. Given information on a population, determine how inbreeding, particularly mating between first cousins, increases the risk of inheriting a rate genetic trait. In the hypothetical island population above, what is the chance that individuals that mate at random will produce a child that is cystic fibrosis? What is the chance of producing a child with the disease if a mating occurs between first cousins? (Answer: random 0. Cousins 0.000000625) 15.
Given information on a population, be able to determine the effects of migration. Assume a population has 100 black lizards, 200 gray lizards and 100 white lizards. Determine the population statistics before and after 50 white lizards leave the population. (Answer: before P=.25, H=.5, Q=.25, p =.5, q =.5 after P =.286, H =.571, Q=.142, p =.5715, q =.4275) 16.
