Population - 🧠ANSWER ✔✔A group of individuals that belong to the same
species and live in the same. (The fundamental unit on which evolution
operates)
Community - 🧠ANSWER ✔✔A set of populations inhabiting a certain area
Species - 🧠ANSWER ✔✔A group of living organisms consisting of similar
individuals capable of exchanging genes or interbreeding.(the most specific
category of classification)
Gene Pool - 🧠ANSWER ✔✔The sum of all the alleles in a population
Hardy-Weinberg Theorem - 🧠ANSWER ✔✔Helps measure changes in
allele frequencies over time
. Provides an "ideal" population to use as a basis of comparison.

,Open Population - 🧠ANSWER ✔✔Is freely exposed to gene flow, as
opposed to a closed one in which there is a barrier to gene flow.
Closed Population - 🧠ANSWER ✔✔A population in which neither
immigration nor emigration occurs. (barrier in gene flow)
Mutation - 🧠ANSWER ✔✔A perminant change in the DNA sequence.
Random Mating - 🧠ANSWER ✔✔A population that is randomly mating will
not make choices in mates that have any advantage in behavior,
appearance, or social aspects.
Non-Random mating - 🧠ANSWER ✔✔Occurs when the probability that two
individuals in a population will mate is not the same for all possible pairs of
individuals.
Natural Selection - 🧠ANSWER ✔✔The pressures the environment puts on
a population.
Microevolution - 🧠ANSWER ✔✔Evolutionary change over a small time
period.
Genetic Drift - 🧠ANSWER ✔✔A change in the allele frequency of a
population as a result of chance events rather than natural selection.

, Bottleneck Effect - 🧠ANSWER ✔✔When a population is subjected to an
event(like a natural disaster) and the survivors do not necessarily represent
the greatest genetic diversity.(Basically its luck who survives not on who's
the fittest.)
Founder Effect - 🧠ANSWER ✔✔When a portion of the population moves
elsewhere and does not necessarily represent the greatest genetic
diversity.
Gene Flow - 🧠ANSWER ✔✔The flow of alleles in and out of a population
due to the migration of individuals.
Camouflage - 🧠ANSWER ✔✔The ability to blend into the surroundings, to
disappear into the background.
Cryptic Coloration - 🧠ANSWER ✔✔Matching objects in the environment
such as rocks, sticks, or leaves.
Distortive Coloration - 🧠ANSWER ✔✔Coloration to confuse predators, by
making it difficult to tell which way the animal is facing, or how many are in
a group.(Zebras)
Warning Coloration - 🧠ANSWER ✔✔Coloration that is either brightly
colored or coloration that contrasts, like black and white.
