Question 1 1 out of 1 points Which of the following best defines an allele? Selected Answer: a. Alleles represent different forms of a given gene Question 2 1 out of 1 points A gene in a population has two alleles where ‘A’ is dominant and ‘a’ is recessive. Homozygous individuals have the genotype: Selected Answer: e. answers a. and b. are correct Question 3 1 out of 1 points What is the frequency of the A1A2 genotype in a population composed of 20 A1A1 individuals, 80 A1A2 individuals and 100 A2A2 individuals? Selected Answer: d. 0.4 Question 4 1 out of 1 points Shifts in gene frequencies can occur between generations simply due to random chance. This phenomenon is called: Selected Answer: a. Genetic drift Question 5 1 out of 1 points Gene flow is defined as: Selected Answer: a.

Unformatted text preview: Principal? Selected Answer: b. The genotype frequencies in the offspring generation must add up to 2 Question 7 1 out of 1 points According to the Hardy-Weinberg equilibrium, genotypic frequencies are represented by the equation: p 2 + 2pq + q 2 = 1. From this equation, the term 'pq' represents: Selected Answer: b. Frequency of the heterozygous genotype Question 8 1 out of 1 points In the exercise we are doing for Lab 5 (Hardy-Weinberg), each (1) coloured bead represents: Selected Answer: a. A single allele Question 9 1 out of 1 points True or false: According to the Hardy-Weinberg Principle, both genotype frequencies and allele frequencies must add up to a total of one (1): Selected Answer: True Question 10 1 out of 1 points The Hardy-Weinberg Principal is important because: Selected Answer: c. It is the null hypothesis for evolution...
