Question

Reason of fast speciation in present day crop plants is

• A. Mutation
• B. Isolation
• C. Polyploidy
• D. Sexual Reproduction

Answer 1

Answer: (C)

Polyploidy

Option $C$ is the correct answer.

The reason of fast speciation in present day crop plant is Polyploidy because it leads to instant speciation by Hybridization and doubling of chromosomes, it involves acquiring $3$ or more times the haploid number of chromosomes, after hybridization the plant gets the desired genome and then chromosome doubling gives it viability, and it plays a very important role in plant evolution.
