Q. Two plants can be conclusively said to belong to the same species if they
A) have more than 90 per cent similar genes
B) look similar and possess identical secondary metabolites
C) have same number of chromosomes
D) can reproduce freely with each other and form seeds
Explanation
[Solution from source] By the biological species concept, members of a species interbreed freely in nature and produce fertile offspring (here, viable seeds). Similar appearance, chromosome number or gene similarity can be shared by different species, so they are not conclusive. Answer (4).
