Question

A species lacking sexual reproduction and delimited by asexual traits is called

• A. Sibling species
• B. Agamospecies
• C. Biospecies
• D. Allochronic species

Answer 1

The correct option is A Sibling species

• Sibling species refers to any of two or more related species that are morphologically nearly identical but are incapable of producing fertile hybrids. For example, the malaria-carrying mosquito of Europe, Anopheles maculipennis and Anopheles atroparvus are morphologically similar and have the same group but they are reproductively isolated and they are unable to produce fertile hybrids
• Sibling species can be identified by genetic, biochemical, behavioural, or ecological factors.
• Hence a species lacking sexual reproduction and delimited by asexual traits is called Sibling species.
• So, the correct answer is 'Sibling species'.
