Question

The biological definition of a species depends on ______.

Options

• differences in the adaptations of two groups of organisms

• reproductive isolation of two groups of organisms

• anatomical and developmental differences between two groups of organisms

• geographic distribution of two groups of organisms

Answer 1

The biological definition of a species depends on reproductive isolation of two groups of organisms.

Explanation:

The biological definition of a species depends primarily on reproductive isolation, meaning members of the same species can interbreed and produce fertile offspring, while reproductive barriers prevent interbreeding with other species. This isolation maintains species distinctness over time.
