1. Population genetics is the study of:
how selective forces change the allele frequencies in the gene pool of a population over time
the genetic basis of population-wide traits
whether traits have a genetic basis
the degree of inbreeding in a population
2. What is the difference between microevolution and macroevolution?
Microevolution describes the evolution of small organisms, such as insects, while macroevolution describes the evolution of large organisms, like people and elephants.
Microevolution describes the evolution of microscopic entities, such as molecules and proteins, while macroevolution describes the evolution of whole organisms.
Microevolution describes the evolution of organisms in populations, while macroevolution describes the evolution of species over long periods of time.
Microevolution describes the evolution of organisms over their lifetimes, while macroevolution describes the evolution of organisms over multiple generations.
3. What is true of populations that are in Hardy-Weinberg equilibrium?
Mating is random.
Organisms are constantly migrating.
Natural selection is occurring.
The populations must be very small.
4. When a population is in Hardy-Weinberg equilibrium, what is not happening to the species?
Reproduction
Evolution
Death
Survival
5. In a population of red (dominant allele) or white flowers in Hardy-Weinberg equilibrium, the frequency of red flowers is 91%.
What is the frequency of the red allele?
9%
30%
91%
70%
6. A population of sheep is in Hardy-Weinberg equilibrium. The allele for white wool (W) has an allele frequency of 0.19, and the allele for black wool (w) has an allele frequency of 0.81.
What is the percentage of heterozygous individuals in the population?
31%
4%
15%
66%
7. The recessive allele b occurs with a frequency of 0.8 in a population of crabs that is in Hardy-Weinberg equilibrium.
What is the frequency of homozygous dominant individuals?
0.32
0.8
0.04
0.64
8. Below is the Hardy-Weinberg equation:
p2 + 2pq + q2 = 1.0
What does p2 represent?
Individuals who have a lethal allele
Individuals who are heterozygous dominant
Individuals who are homozygous recessive
Individuals who are homozygous dominant
