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 21 Which of the following can the results of a QTL tell you? a. The specific causative gene or genes underlying a trait you are studying. b. The heritability of your trait and how much the heritability is influenced by environment. c. Identify haplotypes associated with specific traits of interest in other populations. d. Identification of regions of the genome that are associated with a trait.
QUESTION 46 Consider selection acting against dominant alleles compared to selection acting against recessive alleles. Which will lead to faster allele fixation and why?

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…
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?
I would like to get some help with Question #7 of this Problem Set: Researchers studying beach mice in Florida observed a population and were able to determine the number of individuals of each genotype (Table 1). Table 1. Observed numbers of beach mice with light and dark fur Question 7:
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 11 You are examining a new population that has recently migrated to and colonized a new island. Which of the following characteristics would you expect to see in your population? a. The new population will likely experience genetic drift related issues related to the founder effect. b. The new population will suffer more the effects of mutation because this is a bottleneck event. c. The new population will have high levels of heterozygosity and allelic richness. d. The new population will most likely have the same allele frequencies as the original population.
QUESTION 54 What is the expected inbreeding coefficient for an offspring that is the result of an inbreeding event between siblings? a. 0.25 b. 0.0625 c. 0.125 d. 0.5
Question 18 When fitness is lower at both extremes of phenotypic variation for a trait (e.g., the very largest and very smallest beaks in a bird population) than for the median value in a population, the predominant evolutionary force at work is called Group of answer choices Only 1 correct answer phenotypic selection stabilizing selection directional selection phenotypic choice
42. Kermode bears are found in the central and north coastal regions of British Columbia. Although most Kermode bears have black coats, about 10% of the population have white coats like polar bears. This white coat colour is caused by two autosomal recessive alleles.What is the probability of two black Kermode bears having a male white cub?Answer(Record your answer as a value rounded to two decimal places.)
QUESTION 3 Which of the following is a false statement about the Hardy-Weinberg Principle? a. It needs a large population b. No mutations or natural selection of an allele can occur c. It requires a random mating population. d. Migration is essential to maintain allelic frequency
