A group of similar organisms that can breed and produce fertile offspring.
species
The branch of zoology studying the early development of living things.
Embryology
A natural process resulting in the evolution of organisms best adapted to the environment.
endosymbiosis
natural selection
allele frequency
genetic drift
A trait that helps an organism survive and reproduce in their environment.
gene pool
adaptation
sexual selection
mutation
A rare change in the DNA of a gene, ultimately creating genetic diversity.
mutation
Selective breeding of plants and animals to promote the occurrence of desirable traits in offspring.
artificial selection
natural selection
The process by which different kinds of living organism are believed to have developed from earlier forms during the history of the earth.
Evolution
Types of mutation are:
insertion
base substitution
deletion
base insertion
randomization
frameshift
insertion
base substitution
deletion
frameshift
Movement of alleles from one population to another. Increases the variability of the gene pool.
gene flow
genetic drift
directional selection
gene pool
Match selection type with its definition.
natural selection that favors individuals with either extreme of a trait
disruptive selection
occurs when natural selection favors one of the extreme variations of a trait
directional selection
natural selection that favors intermediate variants by acting against extreme phenotypes
stabilizing selection
Aspect of an organism which enhances the
probability of this organism to survive and
reproduce.
adaptive trait
Evolutionary process whereby an organism
becomes better able to live in its habitat
selection
adaptation
diversity
