Some variation in a species may be a life line for that species if something like a pathogen would attack it and those that are slightly different would have a good change of living while others might not. This is really what evolution is all about.
Because if all of the individuals had the same genetic information then if the species was introduced to a new disease or environment the individuals have the possibility of all dying. If a select few individuals had different DNA that allowed them to be resistant to a disease then they would be able to survive and save the species from extinction.
Genetic variation, caused by mutations in DNA, is a major source of variation within species. Mutations can lead to differences in traits such as color, size, and behavior, allowing for natural selection to act upon these variations.
No, mango leaf is not considered a parallel variation. Parallel variation refers to easy and reversible changes within a species or population, while mango leaf characteristics are part of the natural variation within the species.
Genetic diversity is important for the survival of a species because it increases the chances of individuals having traits that can help them adapt to changing environments or resist diseases. This variation allows a species to better withstand threats and increases its overall resilience.
Of course, variation exists within individuals of the same species. This is because there are a small minority of genes which have multiple alleles in most species. In cases where a subset of the population is isolated from the rest of the population, a subspecies may develop which has particular unique characteristics but can still interbreed with the rest of the species.

Genetic variation, which can lead to evoloution, and then potentially a new species.

Genetic variation
Sometimes positive variation can improve some ability of the species adapted to the environment. For example, a kind of virus can be killed by medicine A. A small part of the virus has some variation that make it can be alive with medicine A. The species of the virus can exist in future, or it will disappear in the future in the environment full of medicine A. Besides, positive variation can provide some capacity for the species to get more resource in the competition. Of course, there is negative variation that might contribute to the disappearance for the species. That is just another side of variation.
Sometimes it is very hard to distinguish between a species where there is a lot of variation between that of a variation that is actually two separate species. Many times scientist disagree on how to tell these two things apart.

Gentic variation is mearsured by the number of species in the given area not.
It is simple to calculate.
