Isolating Mechanisms Bio

pollinator isolation

2 species have different pollinators (usually prevents breeding between plants)

Reproductive Isolation Mechanisms

changes that isolate one species

behavioral isolation

mating behaviors are different so they aren't attracted to each other

gametic isolation

the 2 species have incompatible sperms and eggs

temporal isolation

they don't interbreed b/c their mating periods do not overlap

ecological isolation

when 2 lineages are isolated b/c they live in separate areas

mechanical isolation

when 2 species change dramatically and the changes make it difficult or impossible for them to mate

hybrid inviability (sterility)

when sperm and egg fertilize but the offspring doesn't live
