Try a question

A sample contains 20 AA, 60 Aa and 20 aa individuals. What is the frequency of A?

Try a question

When p = q = 0.5, which expected genotype distribution follows?

Try a question

A recessive phenotype has frequency 0.16 in an equilibrium population. What is the expected heterozygote frequency?

Try a question

Which change can alter genotype frequencies without immediately changing allele frequencies?

Try a question

Which finding most directly supports heterozygote advantage at a locus?

Explain your thinking

Write a short answer, then compare it with a sample and check for missing ideas.

Question 1 of 5

Count the allele pool

A diploid population sample has 40 AA, 80 Aa and 80 aa individuals. Calculate the observed Aa frequency and both allele frequencies. Explain whether this calculation requires equilibrium.

Use N for genotype frequency and 2N for allele frequency.
