Reproductive Isolating Mechanisms
10
hybrid:offspring of parents of two different species
prezygoticisolatingmechanisms:anatomical or behavioral differences between the members of two species that prevent mating or make it unlikely fertilization will take place if mating occurs.
habitatisolation:two species occupy different habitats, even within the same geographic range, so that they are less likely to meet and to attempt to reproduce.
hybridinviability:is when hybrids do not live to reproduce.
behavioralisolation:results from differences in mating behavior between two species
hybridsterility:occurs when the hybrid offspring are sterile
postzygoticisolatingmechanisms:prevent development of a hybrid after mating has taken place.
gameteisolation:incompatibility of gametes of two different species so they cannot fuse to form a zygote
temporalisolation:two species live in the same location, but each reproduces at a different time of year, and so they do not attempt to mate
mechanicalisolation:the result of differences between two species in reproductive structures or other body parts, so that mating is prevented
