Q. Allopatric speciation occurs when

1. genetically related populations inhabit widely separated geographical area
2. genetically unrelated populations inhabit widely separated geographical area
3. genetically related populations inhabit the same geographical area
4. genetically unrelated populations inhabit the same geographical area

Q. Descending approximately 4, 000 years ago from the African wildcat, it has been an exceedingly short time for the domestic cat with respect to genetic evolution and it scarcely seems sufficient to allow the marked physical changes that transformed the animal.

1. Descending approximately 4, 000 years ago from the African wildcat, it has been an exceedingly short time for the domestic cat with respect to genetic evolution and it scarcely seems sufficient to allow the marked physical changes that transformed the animal.
2. The domestic cat descended from the African wildcat approximately 4, 000 years ago, which is an exceedingly short time for the domestic cat’s genetic evolution and scarcely sufficient for the marked physical changes that transformed the animal.
3. Descending from the African wildcat approximately 4, 000 years ago, the domestic cat has had an exceedingly short time for its genetic evolution and has been scarcely sufficient for the marked physical changes in the animal.
4. Having descended from the African wildcat approximately 4, 000 years ago, the domestic cat has had an exceedingly short time for its genetic evolution that has scarcely been sufficient for the marked physical changes that transformed the animal.
5. The domestic cat descended from the African wildcat approximately 4, 000 years ago, an exceedingly recent divergence with respect to genetic evolution and one which scarcely seems sufficient to allow the marked physical changes in the animal.

Q. Allopatric speciation occurs when
