  • Population

Question 4

Question
Genetic variation is
Answer
  • Change over time in the relative frequencies of allele variations

Question 5

Question
Select all that apply. Fitness is a measure of________
Answer

  • The genetic change in a population

Question 6

Question

Question 7

Question
Natural selection and genetic drift cause evolutionary change because______ (select all that apply)
Answer
  • Some alleles become more common in the next generation
  • Some alleles become less common in the next generation
  • It is all about differential reproductive success

Answer
  • Migration
  • Genetic drift
  • Natural selection

Question 9

Question
A mechanism of evolution in which new alleles are added to a population when new individuals enter from another location
Answer
  • Migration

Answer
  • Natural selection
  • One of the mechanisms of evolution

  • False

Question 12

Question
Genetic drift has the biggest impact on small populations
Answer
  • True
  • False

Question 13

Question
Founder effect is where a small number of individuals establish a new population
Answer
  • True
  • False

Question 14

Question
The number of prairie chickens went from millions to fewer than 50, resulting in 30% of alleles being lost. This is an example of______. (Select all that apply)
Answer

Question
Mechanisms for genetic change are_______
Answer
  • Natural selection

Answer
  • True
  • False

Question 21

Question
