Two plants can be conclusively said to belong to the same species if they-
1. have more than 90% genes
2. look similar and possess identical secondary metabolities
3. have same number of chromosomes
4. can reproduce freely with each other to form seeds
The correct option is 4.
A species is a group of closely related organisms that can interbreed freely to produce viable offsprings (seeds).
