Q

Directional Selection

A

One phenotype was favored at one of the extremes of the normal distribution of organisms

17
Q

Stabilizing Selection

A

Means that an organisms in a population with extreme traits was eliminated

18
Q

Disruptive Selection

A

Favors both extremes and selects against common traits

19
Q

Species

A

Organisms are a species when they cannot reproduce and have viable offspring with another organism

20
Q

Speciation

A

The emergence of new species

21
Q

Divergent Evolution

A

Results in closely related species with different behaviors and traits

22
Q

Convergent Evolution

A

Two unrelated and dissimilar species come to have similar traits

23
Q

Allopatric Specitation

A

A population becomes separated from the species through a geographical barrier

24
Q

Sympatric Speciation

A

New species form alongside each other

25
Q

Hardy-Weinberg Law

A

States that even with all the shuffling of genes that occurs, the relative frequencies of genotypes in a species are still there

26
Q

Hardy Weinberg Equation

A

p + q = 1

p^2 + 2pq + q^2 = 1

27
Q

Hardy Weinberg Equilibrium Requirements

A
  • Large Population
  • No Mutations
  • No Immigration/Emigration
  • No Natural Selection
  • Random Mating
28
Q

Genetic Drift

A

Movement of a population from or into a gene pool
