Hardy-Weinberg Intro

Hardy-Weinberg Introduction

Open Ended

Do you think Hardy-Weinberg Equilibrium is realistic? Why or why not?

Multiple Choice

p + q = 1. If p represents the dominant allele frequency, what would q represent?

• the homozygous dominant genotype frequency

• the recessive allele frequency

• the total amount of alleles in the population

• a measure of fitness in the population

Multiple Choice

p + q always equals 1. Which answer choice best explains this?

• 1 individual could have a dominant or a recessive allele.

• The population is in Hardy-Weinberg equilibrium. The 1 indicates that the population has not evolved.

• In terms of frequency, 1 is the highest possible number you can have.

• In terms of frequency, 1 is the same as 100%. All alleles in a population added up give you 100% of the alleles.

Why does it make sense that the frequency of the homozygous dominant genotype is p²?

In your notes, complete a Punnett Square for 2 parents with the genotype pq. How do the results support the Hardy-Weinberg equation? (p² + 2pq + q² = 1)

Multiple Choice

Which values can be plugged into the equation? p + q = 1

• 0.6 and 0.16

• 0.6 and 0.4

• 0.4 and 0.16

• 0.48 and 0.36

Multiple Choice

If 0.49 + 0.42 + 0.09 = 1 (p² + 2pq + q² = 1), what is the value for p?

• 0.09

• 0.07

• 0.7

• 0.9
