Q. Assertion: Somatic hybridization between non-flowering and male sterile dihaploid clones of potato can result in male fertile hybrids. 

Reason: Symmetric hybridization allows for the creation of superior hybrids and the generation of novel genetic material by bypassing traditional sexual reproduction barriers.
