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.

Fill in the Blanks

The gene pool for a population of 10 individuals contains 4 recessive alleles and 16 dominant alleles (20 alleles total). What is the value for p (dominant allele frequency)?

Fill in the Blanks

In a gene pool for a population of 30 individuals, there are 40 recessive alleles and 20 dominant alleles. What is the value for q? (round to hundredths place)

Open Ended

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

Fill in the Blanks

p² + 2pq + q² = 1 Which numeric value should be plugged in for 2pq?

Fill in the Blanks

0.7 + q = 1 What's the missing value?

Fill in the Blanks

0.49 + 2pq + 0.09 =1 Find the value for 2pq.

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
