Genetics Unit 5 Test Review

Changes in genetic material over time

• Gene flow

• Microevolution

• Evolution

• Speciation

Occurs on a small scale, affecting a single species. 

• Charles Darwin

• Frequency

• Fossil

• Microevolution

Occurs on a large scale, and affects species across populations. 

• Macroevolution

• Homologous body structures

• Ancestor

• Trait

“Survival of the fittest”; organisms better able to adapt to their environment survive and reproduce successfully.

• Genetic drift

• Natural Selection

• Fitness

• Allele frequency

Discovered the diversity of life and developed the theory of Natural Selection.

Species- Vary globally, locally, over time.

• Population

• Rosalind Franklin

• Charles Darwin

• Gregory Mendel

A group of organisms, all of the same species that live in a specific area.

• Cladogram

• Clade

• Vestigial body structures

• Population

The organisms from which two or more lineages have descended. 

• Adaptation

• Ancestor

• Phylogenetic tree

• Coevolution

How well an organism can survive and reproduce in its environment.

• Fitness

• Fossil

• Trait

• Gene

Heritable traits that increase an organisms ability to survive and reproduce.

• Founder effect

• Analogous body structures

• Derived character

• Adaptation

An inherited characteristic of an organism.

• Convergent evolution

• Speciation

• Trait

• Frequency
