Speciation

What defines organisms as belonging to the same species?

• They can interbreed and produce fertile offspring.

• They look very similar to each other.

• They share the same genus.

• They can produce offspring, regardless of fertility.

What is a characteristic of a hybrid offspring resulting from the breeding of two different species, such as a zonkey?

• They are always more robust than their parents.

• They are typically sterile and unable to reproduce.

• They can only reproduce with one of the parent species.

• They are genetically identical to one of their parents.

Which type of speciation involves a geographic barrier that separates populations, preventing them from interbreeding and sharing the same gene pool?

• Sympatric speciation

• Temporal speciation

• Allopatric speciation

• Behavioral speciation
