Random change in a gene that can be passed on to an offspring.
MUTATION
HW equilibrium does not permit this evolutionary force to occur.
NATURAL SELECTION
A bell curve is sharpened upwards.
STABILIZING SELECTION
A type of curve seen by a population with unchecked growth that eventually levels off.
LOGISTIC
Reshuffling of genes in a diploid individual that happens during meiosis.
RECOMBINATION
In nature, individuals are picky about their mates, preventing this HW principle from occurring.
RANDOM MATING
Type of selection tied to assortative mating.
SEXUAL SELECTION
The dominant allele frequency in a population is 0.65. What is the recessive allele frequency?
0.35
Each organism produces a large number of these, which pair randomly.
GAMETES
Gene flow must be prevented for HW equilibrium to occur, meaning organisms cannot perform this.
IMMIGRATION/EMIGRATION
MIGRATION
Both extreme ends of a trait allow better survival.
DISRUPTIVE SELECTION
Type of organism strategy that shows rapid reproduction and high numbers with low parental involvement.
R-SELECTION/STRATEGIST
Besides environment, this factor plays a heavy influence on variation, involving inheritance from parents.
HEREDITY
A population must be at this size for HW equilibrium.
INFINITELY LARGE
A trait is shifted towards an extreme variant.
DIRECTIONAL SELECTION
Full equation to discover frequencies of homozygotes and heterozygotes in a population.
p2 + 2pq + q2 = 1
Type of survivorship curve that humans generally exhibit.
TYPE I
Genetic drift has a much more profound effect on this type of population.
SMALL
Overall type of selection exhibited by any change in trait frequency.
NATURAL SELECTION
An organism’s strategy that means they will likely experience a single reproductive episode before death.
SEMELPARITY
