Mechanisms of Evolution

Question 1

Gene pool

Answer 1

Total of all alleles within the population

Question 2

Allele frequency

Answer 2

Determines the genetic characteristic of that population

Question 3

Microevolution

Answer 3

Changing percentages pr frequencies of alleles within populations leads to evolution within a population

Question 4

Factors that cause evolutionary change

Answer 4

Mutation, gene flow, non-random mating, genetic drift > founder effect, bottle neck effect, and natural selection

Question 5

Mutation

Answer 5

Random change in the DNA of an individual

Question 6

Gene flow

Answer 6

When individuals move from one population to another, they alter the allele frequency of both populations

Question 7

Non-random mating

Answer 7

Mating among individuals on the basis of mate selection for a particular phenotype or due to inbreeding

Question 8

Genetic drift

Answer 8

Change in frequency of alleles due to chance events in a breeding population

Question 9

Founder effect

Answer 9

A change in gene pool that results when a few individuals start a new isolated population

Question 10

Bottle neck effect

Answer 10

Changes in gene distribution that results from a rapid decrease in population size
