VARIATION
HARDY-WEINBERG
SELECTION
POTPOURRI
200

Random change in a gene that can be passed on to an offspring.

MUTATION

200

HW equilibrium does not permit this evolutionary force to occur.

NATURAL SELECTION

200

A bell curve is sharpened upwards.

STABILIZING SELECTION

200

A type of curve seen by a population with unchecked growth that eventually levels off.

LOGISTIC

400

Reshuffling of genes in a diploid individual that happens during meiosis.

RECOMBINATION

400

In nature, individuals are picky about their mates, preventing this HW principle from occurring.

RANDOM MATING

400

Type of selection tied to assortative mating.

SEXUAL SELECTION

400

The dominant allele frequency in a population is 0.65. What is the recessive allele frequency?

0.35

600

Each organism produces a large number of these, which pair randomly.

GAMETES

600

Gene flow must be prevented for HW equilibrium to occur, meaning organisms cannot perform this.

IMMIGRATION/EMIGRATION

MIGRATION

600

Both extreme ends of a trait allow better survival.

DISRUPTIVE SELECTION

600

Type of organism strategy that shows rapid reproduction and high numbers with low parental involvement.

R-SELECTION/STRATEGIST

800

Besides environment, this factor plays a heavy influence on variation, involving inheritance from parents.

HEREDITY

800

A population must be at this size for HW equilibrium.

INFINITELY LARGE

800

A trait is shifted towards an extreme variant.

DIRECTIONAL SELECTION

800

Full equation to discover frequencies of homozygotes and heterozygotes in a population.

p2 + 2pq + q2 = 1

1000

Type of survivorship curve that humans generally exhibit.

TYPE I

1000

Genetic drift has a much more profound effect on this type of population.

SMALL

1000

Overall type of selection exhibited by any change in trait frequency.

NATURAL SELECTION

1000

An organism’s strategy that means they will likely experience a single reproductive episode before death.
