Answer 2

Change in a DNA sequence

Question 3

Which evolutionary process is the only one that can generate new genetic information?

Answer 3

Mutation

Question 4

Gene flow

Answer 4

Movement of alleles from one population to another by migration

Question 5

Migration

Answer 5

Movement of individuals from one population to another

Question 6

Genetic drift

Answer 6

Chance alteration of allele frequencies in a population

Question 7

Founder effect

Answer 7

Colonization of new habitat by a few individuals that then give rise to a new population

Question 8

Population bottleneck

Answer 8

Following substantial population decline, surviving individuals do not represent the genetic diversity of the original population

Question 9

Sexual selection

Answer 9

Differential reproductive success based on differences in obtaining mates

Question 10

Allopatric speciation

Answer 10

Geographical range of species is split in discontinuous parts by formation of barriers to gene flow
