At least thatmanyphenotypesare usuallydemonstrated populationsamples [e.g., Stevensonand Schanfield(1981)]. However,Anabaptisthistoryis a chronicleof repeatedmigrationsand fissionsand in some cases fusionsof varioussubgroups. The Amishbecamereproductively isolatedfrommostMennonitesearly in Anabaptisthistory.This is forcefully demonstrated by theprincipalcomponentsanalyses,in whichthe Amish are clearlyisolated relativeto other populationsin thethree-dimensional plots.Theyare distinguished by thefirst and second factorsin Figures 3 and 4, respectively.The extremesin gene frequencies[includingrelativelyhigh frequenciesof ABO*A, MNS*N, and RH d and comparatively low frequenciesof AB0*0, ABO*B> MNS*N, and RH D notedby Juberget al. (1971)] do not obscuretheirorigins,however.

As expected,the GM haplotypefrequenciesforthe Kansas and Nebraskacommunitiesare similarto fromeach thefrequenciesforcentralEurope and are only slightlydifferent other.

Overall,theseresultsare consistentwiththeanalysesof Crawfordet al. noted (1989) usingredcell antigensand blood proteins.The maindifference is theincreaseddistinctiveness of theMeridiancongregation'sgeneticstructurewhenGM is includedin theanalysis. Conclusions The presentation of immunoglobulin phenotypeand haplotypedistributionsforthe Anabaptistpopulationsamples do not reveal any surprises.
