Different mice have different alleles
Any difference between two indivisuals of the same species For example: Eye colour, Hair colour etc is called Variation
A transgenic organism is an organism that has been modified genetically from a different species to caries traits from another species. One example is a GMO crop.

Some traits are derived from the species' genome, and a species is defined as a group of organisms that are genetically similar enough to leave fertile offspring.
Different traits in a organism
Different mice have different alleles
It is a diversification of traits within a species. An example of this is ladybugs with different numbers of spots.

Related species have inherited homologous traits from a common ancestor.
a new species might form when a group of individuals remains sparated from the rest of its species long enough to accumulate different traits
Geographic isolation is a way in which a new species can form. Isolation over a long enough period of time can result in a species evolving to have different traits.

Variation is caused by new genetic mutations in a population which lead to different traits in a population. Evolution selets the most useful of these mutation, eventually leading to prominence of new traits within a species or population, or even new species.
