Question 1.You have sampled a population in which you know that the percentage of the homozygous recessive genotype (aa) is 36%. Using that 36%, calculate the following: A) The frequency of the "aa" genotype. B) The frequency of the "a" allele. C) frequency of the a allele, then the frequency is 60%. D) The frequency of the "A" allele. E) frequency of A is by definition equal to p, so the answer is 40%. F) The frequencies of the genotypes "AA" and "Aa." G)The frequencies of the two possible phenotypes if "A" is completely dominant over "a."
Question 5 A rather large population of organisms have 396 red-sided individuals and 557 tan-sided individuals. Assume that red is totally recessive. Please calculate the following: a) The allele frequencies of each allele b) The expected genotype frequencies. c) The number of heterozygous individuals that you would predict to be in this population. d) The expected phenotype frequencies. e) Conditions happen to be really good this year for breeding and next year there are 1,245 offspring. Assuming that all of the Hardy-Weinberg conditions are met, how many of these would you expect to be red-sided and how many tan-sided?
Question 3. There are 100 students in a class. Ninety-six did well in the course whereas four blew it totally and received a grade of F. Sorry. In the highly unlikely event that these traits are genetic rather than environmental, if these traits involve dominant and recessive alleles, and if the four (4%) represent the frequency of the homozygous recessive condition, please calculate the following: A) The frequency of the recessive allele. B) The frequency of the dominant allele. C) The frequency of heterozygous individuals. Question 4 Within a population of butterflies, the colour brown (B) is dominant over the colour white (b). And, 40% of all butterflies are white. Given this simple information, which is something that is very likely to be on an exam, calculate the following: A) The percentage of butterflies in the population that are heterozygous. B) The frequency of homozygous dominant individuals. Question 5 A rather large population of organisms have 396 red-sided individuals…
QUESTION 26 When thinking about changes in allele frequencies over time, why do you care more about the effective population size rather than the census (total number of individuals) population size?

QUESTION 35 You are conducting a QTL analysis to better understand monkey flower color and shape. To begin you start with breeding a plant that produces a long white tubular flower with purple flat flower. You continue your breeding for many generations. Which of the following is something you most likely observe? a. Variation in flowers your F2 population far exceeded the parental generation characteristics. b. The flower phenotypes did not correlate between siblings and between parent-offspring pairs. c. The variation in phenotypes is greater in the F2 population compared to the F1 population. d. Through selective breeding of the F1 individuals you could not recover the parental generation.
QUESTION 29 You are interested in selecting for increased brain size in Fisher cardinals. You’ve chosen three traits that seem to correlate with brain size. a. Calculate the heritability of each trait (H2 = Vg/Vp). Trait: Vg Vp H2 Skull size 1.36 6.08 ______ Ability to find food 5.33 5.98 ______ b. For which of the following traits would there be a stronger correlation between parent and offspring?
QUESTION 38 All of the following are true statements about the Hardy-Weinberg Equilibrium (HWE) principle, EXCEPT: a. HWE concludes that allele frequencies change over time. b. HWE principle assumes that all of the individuals in your population survive and reproduce equally. c. HWE concludes that if given the allele frequencies we can then accurately predict the genotype frequencies in the population. d. HWE principle assumes large, completely isolated populations.
Question 1.You have sampled a population in which you know that the percentage of the homozygous recessive genotype (aa) is 36%. Using that 36%, calculate the following: A) The frequency of the "aa" genotype. B) The frequency of the "a" allele. C) frequency of the a allele, then the frequency is 60%. Question 6A very large population of randomly-mating laboratory mice contains 35% white mice. White colouring is caused by the double recessive genotype, "aa". Calculate allelic and genotypic frequencies for this population. Question 7After graduation, you and 19 of your closest friends (lets say altogether 10 males and 10 females) charter a plane to go on a round-the-world tour. Unfortunately, you all crash land (safely) on a deserted island. No one finds you and you start a new population totally isolated from the rest of the world. Two of your friends carry (i.e. are heterozygous for) the recessive cystic fibrosis allele (c). Assuming that the frequency of this allele does not change as…
