Question regarding genetics

They add up over time.Also remember that even species with different chromosome numbers can still produce viable offspring and sometimes, rarely, the offspring can be fertile.Horses and donkeys producing mules and hinnys are an example.Oh,......
You mentioned the idea that a mutant wouldn't be able to mate with a normal individual. You are assuming some huge change happening very suddenly. That rarely happens. Mostly it is just a little misspelling here and there. They add up over time. Also remember that even species with different chromosome numbers can still produce viable offspring and sometimes, rarely, the offspring can be fertile. Horses and donkeys producing mules and hinnys are an example.
Oh, and Merry Christmas to you too!

A mutation is a permanent change in the DNA sequence of a gene. Mutations in a gene's DNA sequence can alter the amino acid sequence of the protein encoded by the gene.Because of that It will change the protein synthesis in our body.There are different types of mutation.
By pattern of inheritance The human genome contains two copies of each gene – a paternal and a maternal allele.
A heterozygous mutation is a mutation of only one allele.
A homozygous mutation is an identical mutation of both the paternal and maternal alleles.
A homozygous mutation can pass on those traits to its offspring. When a mutation occur in sex chromosomes, It can pass through their generation.

Well as a 14 year old (me) you might not believe me answer. But here it goes, if a "raccoon" for example is genetically mutated by something, that means that whatever had mutated it got into it's cellular chromosomes and into the underlying DNA molecules inside. That means all the traits and alleles inside the raccoon's DNA are altered, and because his sperm carries his DNA, that sperm will hold all the mutated DNA along with it. So when it mates, those "mutated" chromosomes merge with the female raccoon's egg and when those cells divide into more and more cells, all the DNA put into from the males side, will still have those mutations, thus creating a new organism with the mutated DNA from the father. Also, this same concept applies to all other species of animals including humans! So please don't go playing with radiation or something and thinking of having a child. Well anyway, I really hope this helped.
