A population is said to be in H-W equilibrium IF:

(select ALL that apply)

• allele frequencies are constant from one generation to the next

• all 5 H-W conditions are met

• at least 3 of the 5 H-W conditions are met

• allele frequencies change from one generation to the next

If a recessive disorder is found to affect 1 in 500 live births, what is the frequency of the dominant allele?

• 0.002

• 0.9553

• 0.0447

• 0.9125

• 0.2

• 0.48

• 0.6

• 0.8

In a population of sandworms, 89% of individuals have small eyes (aa) and 11% of the population have large eyes. What is the frequency of the recessive allele in this population?

• 0.057

In a population of newts, producing toxin is a recessive trait, while not producing toxin is dominant.

In this population of newts, 387 / 587 newts do not produce toxin. What is the frequency of newts that are heterozygous in the population?

Round to the hundredths place.

Which of these is a condition that must be met for Hardy-Weinberg equilibrium?

• small population size

• No natural selection

• Gene flow

• Nonrandom mating

• Mutations

The purpose of the Hardy-Weinberg equilibrium theory is to use math to demonstrate whether or not evolution is occurring by measuring (a)   frequencies over several generations.
