Abstract: Populations of Alaskan muskoxen (Ovibos moschatus) are derived from 34 animals transplanted from East Greenland in the 1930s.The possibility of a founder effect following this transplant was investigated.Muscle, liver and plasma samples from 87 Alaskan animals and 39 Greenlandic animals were analyzed using polyacrylamide and starch gel electrophoresis.A total of 38 enzyme and non-enzymatic protein systems, coded by 58 presumptive loci, was tested for activity; 28 loci were considered usable.One locus (Esterase-2) was polymorphic; the proportion of polymorphic loci was 0.036 (95% criterion).The mean heterozygosity per individual was 0.006 in the Greenlandic population and 0.011 in the Alaskan population.The allele frequencies at the Est-2 locus were similar in both populations.No heterozygote deficiency and no evidence of a founder effect were seen in the Alaskan population.This may be a consequence of the low level of allozymic variation seen in muskoxen in general.8 NLH, and Michael H. Smith, Director, SREL, for allowing me the use of their respective facilities and for their encouragement.A travel grant from the Vice-Chancellor for Research and Advanced Study, UAF, was awarded to help defray costs.Of the many people at UAF who contributed to my project, I would especially like to thank Dr. Keith Miller for the loan of the circulating pump, Dr. George Stevens for editorial advice, Clay Cranor for statistical assistance, and Christopher A. Babcock for the good vibrations lab coat.For action exceeding the call of duty, may I single out Don Borchert, IAB, for incredible patience in matters of photography; my former roommates, Cristine Linesch and Connie O'Brien Zachel, for maintaining try blood sugar level; and the men in my life, my grandfather, Isaac Fleischman, ny father, Milton W. Fleischman, and ny husband, Richard S. Noll, for each taking his turn in contributing to the support of my academic development.
