Lab 7 Worksheet

Q • Question 1 4 out of 6 points The Hardy-Weinberg equation, p2 + 2pq + q2 = 1, applies to any locus that has only two available alleles. According to the CONCEPTS of Lab 7 video, what is p and what is q? How many possible genotypes for a locus that has only two available alleles? How do you calculate the frequency of each genotype? • Question 2 1 out of 1 points For a locus that has only two available alleles, if p is 25%, how much is q? • Question 3 1 out of 1 points According to the CONCEPTS, if p changes for a population from generation to generation, can you conclude that the population is evolving? • Question 4 5 out of 5 points List all the assumptions of the Hardy-Weinberg equilibrium in your own words. Copied answers receive no credits. • Question 5 0 out of 2 points In your Spreadsheet 1, why is the allele A number of the next generation calculated as 2*H28+I28?

1.Selected Answer: P shows the allele frequency of the dominant allele, q shows the frequency of the recessive allele. The possible genotypes are AA, Aa, and aa. To find the frequency of each genotype, the number of genotypes is divided by the total number o possible genotypes. 2.Selected Answer: As p+q=1 so if p=25% (0.25) then q should be 75% (0.75). 3.Selected Answer: If p changes for a population then gene frequency will change and will show that population is evolving.
