You are studying speciation in crickets. You find that males and females from different populations will mate, but few eggs get fertilized. This is an example of what type of reproductive isolating barrier?
A) pre-mating
B) post-mating, prezygotic
C) intrinsic postzygotic
D) extrinsic postzygotic
Post-mating, Prezygotic
Describes reproductive barriers that occur after mating but before the formation of a zygote, such as sperm-egg incompatibility.
Reproductive Isolating Barrier
Factors that prevent different species from interbreeding, thus maintaining species boundaries.
Eggs Get Fertilized
The process by which sperm and egg unite to form a zygote, initiating the development of a new organism.
- Determine the diverse mechanisms of reproductive isolation and segregate them into prezygotic and postzygotic types.
