Once species have formed,they keep their identity by

Question

Quizplus · Accepted Answer

Isolating mechanisms prevent interbreeding between different species and thus maintain their distinct identities. Developmental differences, somatic mutations, and structural modifications may cause variation within a species but do not prevent interbreeding with other members of the same species. Genetic blocks may contribute to reproductive isolation but alone are not sufficient to maintain species identity.
