There are a set number of genes for every species.
Do you know what a gene is? I suspect not.

If there was some genetic mutation in an offspring of one species, making that offspring have a different number of genes than their parents, then that offspring would quite simply not be of the same species as her parents or her playmates.
That's just not true. Gene duplication has been observed and documented. See, for example,

Since the genetic anomaly cannot reproduce with other animal of her parent's species, then she would have to find another animal of the exact same genetic mutation.
Nonsense. Read the above examples. Besides, you talk as if all organisms reproduce sexually. Quite limited thinking. What about the vast numbers of asexually reproducing organisms? What about the examples of parthenogenetic organisms, including examples of plants, fish, invertebrates (bees, wasps, aphids), reptiles, and sometimes birds. Even more importantly, gene duplication doesn't seem to create an impediment to normal sexual reproduction in sexually reproducing species (see examples in the above cited works).

The sheer possibility [sic] of that proves that evolution will forever be an unproven theory.
Hopefully you are aware that you just said that evolution is possible. However, your statement displays a complete lack of knowledge of what science is and how it works. In science, the best it ever gets is a theory. It gets so tiring explaining to those who haven't bothered to learn what they are talking about before they speak over and over again.
