Identify the mechanism for isolation described using the drop-down menus.
the red-legged frog breeds in ephemeral ponds from january through march. its relative, the bullfrog, breeds in permanent ponds from late march through may.

a)geographical isolation
b)anatomical isolation
c)behavioral isolation
d)temporal isolation

The correct answer is option D, Temporal isolation

Temporal isolation is the mechanism which prevents the mating of closely related species living in the same ecosystem. Basically the reproductive barriers prevent these species from interbreeding. Temporal isolation is a prezygotic barrier that causes “time isolation” between the breeding period of two closely related species. The difference in time could be “difference in time of day”, “ difference in season of mating”, “difference in months” and in some cases “ difference in years”.

d i think its   answer d

•there must be variation for the particular trait within a population.

•the variation must be inheritable (that is, it must be capable of being passed on from the parents to their offspring).

•individuals with one version of the trait must produce more offspring than those with a different version of the trait.good
