Question

How the genetic manipulation occur in plants .what is manipulation

Answer 1

Genetic manipulation is, in essence, a process done to manipulate the genome of an organism in order to produce desired traits. In the past, this was achieved by selective breeding. 
Modern genetic manipulation makes breeding plants and animals with the desired traits more efficient. It uses genetic engineering to build the genesto give an organism the desired traits and uses biotechnology to introduce the trait into the genome.

Answer 2

Other methods include genesequencing, which involves the mapping of an organism's genome. Genetic manipulationisn't without its controversies, however. Modern genetic manipulation is more controversial than selective breeding because it allows humans to have control over which traits are seen
