in gene pool, it comes from a random mutation
By sexual reproduction of far off relatives. Because of genetics there can be mutations and then there is always such concepts as survival of the fittest and natural selection. For example, if a certain species of moths are generally white, but pollution causes them to stand out in the north because of this, those that have a gray colored mutation become the ones most likely to survive and the white ones die out, leaving the gray variation. This combines both survival of the fittest and natural selection.
No two individuals are exactly alike. They all vary slightly in their DNA.
What we would call a mutation.
the genetic variation isappearanceor the genes members of the same species of the same group.
Intraspecific variation
All animals adapt to their living conditions, which causes them to mutate and therefore look different, even those of the same species
genetic variation happens because of meiosis. chromosomes are randomly in each sperm/egg cell, and so when they come together it's unlikely to get the same combination twice
Interspecific cooperation refers to help or assistance of individuals belonging to different species (a case of this is mutualism), whereas intraspecific cooperation is observed between individuals within the same species
There are many many species of mussels but their anatomy is pretty much the same with some variation that distinguishes them as species.
They have different genotype and phenotype i.e. they have genes in different manners in according to recessive or dominant which make variations in their characters
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.

The animals with the abilities that will help them to survive better than those without the same abilities will likely survive longer and will not be killed by predators. Those animals will live on and give their children the same abilities to survive, helping the species to adapt to a hostile environment.
Yes. Species are listed under genera.
Any difference between two indivisuals of the same species For example: Eye colour, Hair colour etc is called Variation
