◉ frequency-dependent selection.
Answer: the fitness of a phenotype depends on how common it is in
the population
◉ speciation.
Answer: the process by which one species splits into two or more
species
diverge from parent species
◉ species.
Answer: a group of populations whose members have potential to
interbreed in nature & produce fertile offspring
◉ reproductive isolation.
Answer: the existence of biological factors (barriers) that impede
members of two species from producing viable, fertile offspring
, ◉ hybrids.
Answer: offspring from the mating of individuals from two different
species or from two true breeding varieties of the same species
◉ reproductive barriers.
Answer: biological features of the organism that prevent individuals
of different species from interbreeding successfully
prezygotic and postzygotic
◉ prezygotic barriers.
Answer: Barriers that impede mating or hinder fertilization
◉ postzygotic barriers.
Answer: Barriers that prevent the hybrid zygote from becoming a
fertile adult
◉ allopatric speciation.
Answer: the formation of new species in populations that are
geographically isolated from one another
no/limited gene flow
