When the reproductive cells of different species are incompatible and cannot accomplish fertilization, it is referred to as:
A) hybrid sterility.
B) gametic isolation.
C) gametic breakdown.
D) temporal isolation.
E) behavioral isolation.
Gametic Isolation
A prezygotic reproductive barrier where the gametes (egg and sperm) of different species fail to unite or recognize each other, preventing fertilization.
Hybrid Sterility
A condition where offspring from the crossbreeding of two different species are unable to reproduce.
Fertilization
The union of male and female gametes to form a zygote, initiating the development of a new individual organism.
