H-W Equilibrium Review

A scientist studies a population of lizards to determine whether or not the population is evolving.

Click on the condition(s) that would cause the population to be in Hardy-Weinberg equilibrium.

• Mating is random

• The lizard population is small

• No lizards migrate in or out of the population

• Natural selection is not occurring in the population

• A new mutation occurs within the population

Allele frequencies​ ​ (a)   will​ ​ (b)  

• in a popultation
• for an individual
• will remain constant
• change

Which of the following is NOT a condition for Hardy-Weinberg equilibrium?

• Large population

• Random mating

• Frequent mutations

• No natural selection

Why are real-world populations rarely in Hardy-Weinberg equilibrium?

• All populations are in Hardy-Weinberg equilibrium

• Due to frequent mutations

• Because they rarely meet the five required conditions

• Because they satisfy all five conditions

Small populations are not susceptible to changes in allele frequencies in Hardy-Weinberg Equilibrium.

• True

• False
