Back

0.9553

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 'a' in this population?

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

Back

No natural selection

Front

Define Hardy-Weinberg equilibrium.

Back

A principle that describes the genetic variation in a population that remains constant from one generation to the next in the absence of disturbing factors.

Front

What are the five conditions for Hardy-Weinberg equilibrium?

Back

1. No mutations 2. Random mating 3. No natural selection 4. Extremely large population size 5. No gene flow (migration)

Front

What is the Hardy-Weinberg equation?

Back

p² + 2pq + q² = 1, where p is the frequency of the dominant allele and q is the frequency of the recessive allele.

Front

If the frequency of the recessive allele is 0.2, what is the frequency of the dominant allele?

Back

0.8

Front

What does 'p' represent in the Hardy-Weinberg equation?

Back

The frequency of the dominant allele.
