Assertion: Somaclonal variations produce slight differences in plant. Reason: They are produced while performing tissue culture.

Assertion : A single mutation may produce a new species . Reason : Mutation may cause major variation in genetic material and these are inheritable .

Assertion:Meiosis causes variations in population from one generation to the next. Variations are very important for the process of evolution.

Assertion :- Human exploited the variatins that variations that were present naurally in the wild populations of plants & animals. Reason :- Variation is the degree by which progeny remembles from their parents.

Assertion: Variations are important for the process of evolution. Reason: Meiosis increases the genetic variability in the population of organisms from one generation ot the next.

Mutation breeding is a process through which one gene from a parent transfer in to another and produce recombinant similar to parent. Reason : - Somatic hybridization does not induce variation.
