Which of the following is an example of reproductive isolation?
a.)two populations of finches that cannot produce viable offspring
b.)two populations of finches that have different feather colors
c.)two populations of salamanders that live in different lakes
d.)two populations of salamanders that have different tail lengths

A.) two populations of finches that cannot produce viable offspring.

Reproductive isolation refers to the phenomena in which members of the same species (intraspecific) or of different species (interspecific) are incapable of interbreeding because of behavioral, physiological, biological and geographical barriers.These species cannot produce viable fertile offsprings.

According to the above information, two populations of finches that cannot produce viable offspring is the correct example of the reproductive isolation. This is because of the fact that the two populations of the finches may either belong to same species or different species but due to the barriers like behavior, physiology and morphology they are incapable of interbreeding and producing viable fertile offsprings.
