reproductive isolation Flashcards
what is prezygotic isolation?
barriers that prevent mating or the formation of a zygote.
what is postzygotic isolation?
the zygote is able to form, but does not survive to produce fertile offspring.
what is temporal isolation?
the times of breeding are different stopping breeding
what is behavioural isolation?
the courtship rituals are different stopping breeding
what is ecological isolation?
the places where the organisms live are different stopping breeding.
what is mechanical isolation?
the sizes of the mating organs are different stopping breeding
what is gametic isolation?
the egg and the sperm are incompatible stopping the formation of the zygote.
what is hybrid inviability?
the organisms can mate and form offspring, however, the zygote is not strong enough to survive until adulthood.
what is hybrid sterility?
the organisms can mate and form offspring, but it is sterile meaning it cannot produce offspring of its own.
