Question

Allopatric but not sympatric speciation requires ______.

Options

• spontaneous differences in males and females

• geographic isolation

• reproductive isolation

• prior hybridization

Answer 1

Allopatric but not sympatric speciation requires geographic isolation.

Explanation:

Allopatric speciation requires geographic isolation to separate populations, preventing gene flow between them, which eventually leads to the formation of new species. Sympatric speciation, on the other hand, occurs without geographic isolation, usually through other mechanisms like reproductive isolation within the same area.
