Question

Two plants can be conclusively said to belong to the same species, if they

• A. Can reproduce freely with each other and form seeds
• B. Have more than 90 percent similar genes
• C. Look similar and possess identical secondary metabolites
• D. Have same number of chromosomes

Answer 1

The correct option is A Can reproduce freely with each other and form seeds

Species refers to the basic unit of biological classification and a taxonomic rank, it defines a group of potentially interbreeding natural populations and can be reproductively isolated from other similar groups. While a molecular marker would have given a clearer distinction, this works out as a useful formulation that shows the impact of sexual reproduction on the dynamics of natural selection.

Therefore, the correct answer is option A.
