... population. The MHC polymorphism in the population might be formed by different mechanisms. The antigen-presenting MHC class II molecules are very polymorphic and there exist several alleles of the genes in the population. It is this feature which makes them interesting for donor-recipient matching ...

Polymorphism and Mutation

... of genes that have changed enough to create variation within a group. It is these changes that can lead to evolutionary changes since if this polymorphic change is beneficial it will continue to spread within the group as new offspring are produced. I suppose a mutation may become a polymorphism ...

Re: Evolutionists Show of Shutting Down the Debate

... difference between a state where a gene has more than one form, and the various forms themselves. I agree that loci can be referred to as being polymorphic if they contain polymorphisms - ie. the loci possess "many forms". The word "polymorphism", unfortunately for our discussion, ...
