___ sickle cell anemia

___ hemophilia

___ huntington’s

___ red-green colorblindness

___ PKU

___ Tay-Sach’s

B. sex-linked recessive, cannot distinguish red/green

15.

Match the term with the correct definition a.

Evolution b.

Natural selection c.

Darwin e.

Artificial selection f.

Genetic equilibrium g.

h.

i.

Divergent evolution

Convergent evolution

Mimicry j.

Camouflage k.

Homologous structures l.

Analogous structures

Structures with the same function found in animals that have a different common ancestor

Caused by random events that remove genes from a population

Theory that living things come from other living things

Structures found in organisms with common evolutionary ancestry

Adaptation in which one animal resembles another

Scientist who proposed the idea of evolution by natural selection

This is an adaptation that aids in the survival of an organism

Change in populations over time

Type of evolution in which species evolve to be different even though they have a common ancestor

Breeding an organism with specific traits

Evolution is not occurring because the frequency of alleles stays the same over generations

Adaptation that allows an animal to blend in with its surroundings

Type of evolution in which a species evolves to be similar, no common ancestor
