Stuff flynn needs to remember from practice test

Question 1

What is adaptive radiation?

Answer 1

The rapid evolution of many diverse species from a common ancestor, each adapted to different environments or niches.

Question 2

What is gene flow?

Answer 2

The transfer of genetic material between populations of the same species, usually through migration or interbreeding, which increases genetic variation within populations.

Question 3

What is genetic drift?

Answer 3

The random change in allele frequencies in a population due to chance events, especially significant in small populations.

Question 4

What is the founder effect?

Answer 4

The loss of genetic variation when a new population is established by a small group of individuals, leading to reduced genetic diversity and potentially unique genetic traits.

Question 5

What is speciation?

Answer 5

Speciation is the process by which one population splits into two or more distinct species, usually through the buildup of genetic differences and reproductive isolation
