Question

What determines if two organisms are the same species?

Answer 1

Answer:

According to the biological species concept, organisms belong to the same species if they can interbreed to produce viable, fertile offspring. Species are separated from one another by prezygotic and postzygotic barriers, which prevent mating or the production of viable, fertile offspring.

Answer 2

Answer:

The biological species idea states that organisms can only interbreed and generate viable, fruitful offspring within their own species.

Explanation:

• Prezygotic and postzygotic barriers exist between species, preventing mating or the generation of viable, fruitful offspring.

• The process by which new species emerge is known as speciation. It happens when populations within a species separate and experience reproductive isolation.
• A period of geographic separation causes groups from an ancestral population to diverge into distinct species in allopatric speciation.
• Without any geographical separation, groups from the same ancestral population diverge into distinct species in a process known as sympatric speciation.
