Reproductive Isolation Submitted By: Michaela Tinker

Reproductive Isolation This happens when members of two populations can no longer interbreed and produce fertile offspring. The three types of reproductive isolation are: Behavioral Isolation Geographic Isolation Temporal Isolation

Behavioral Isolation This happens when two or more populations have different reproductive behaviors or different ways of courtship. Both of these species are similar, but the first species is doing a courting dance while the second species is doing a pointing display.

Geographic Isolation This happens when populations are separated by geographic barriers. The Isthmus of Panama separates the Porkfish from the Panamic Porkfish.

Temporal Isolation This happens when two populations reproduce at different times of the year. The Spring field cricket reproduces in the Spring while the Fall field cricket reproduces in the Fall.
