WebJun 20, 2000 · A central thesis of Stebbins' seminal book, Variation and Evolution in Plants (), is the notion that to understand evolution we must examine its action at the level of populations within species.This reasoning may seem obvious to contemporary readers, but at the time of Stebbins' writing, the importance of population-level processes for evolution … WebDec 16, 2016 · Citrus sudden death-associated virus (CSDaV) is a monopartite positive-sense single-stranded RNA virus that was suggested to be associated with citrus sudden …
WebOrganisms with the same heredity have been found to show the following types of variation: (1) The fluctuating or continuous variations are very common. It is very difficult to find two leaves on the same plant which are exactly alike. This variation is caused more by ‘nurture’ than by hereditary ‘nature’.

WebDec 14, 2015 · In nature, variation occurs mainly as a result of mutations and without it, plant breeding would be impossible. In this context, the major aim in mutation-based breeding is to develop and improve well-adapted plant varieties by modifying one or two major traits to increase their productivity or quality.
