Well, if there were a number of different mutations that were alleles of the same gene only a maximum of two of them could be present. I guess thats one possible way that a mutation could be eliminated. Genes are paired so you could only have two mutations at a time that were alleles of a specific locus. Human blood type for instance. There are basically 4 different blood types. A, B, AB, and O. A and B are codominant to each other and O is recessive to both. The possible combinations are.

AA - Blood type A
AO - Blood type A
BB - Blood type B
BO - Blood type B
AB - Blood type AB
OO - Blood type O

There is only space for two types on the gene which is why you would never see a blood type of ABO. I guess in this way you could 'eliminate' a mutation. Does that make sense? I'm sorry if I explained it poorly, I'm certainly not an expert.
