Can I have a list of suggestions, such as the mutated allele, other allele, etc. ? Are there any blatantly missing ones on my short list?
Usually its major allele and minor allele. When you hear this language, you feel that the major allele is the 'wild' type, but its more precise to avoid 'wild'.
This language avoids the question of which one is 'wild' since different populations may have different ratios of the two.
Wild type refers to the phenotype of the typical form. Normally it is wild type is being compared to a mutant allele because the allele is not longer typical. So the answer would an allele that is not typical which, in most cases is a mutated allele.
