Spatial Variation in Transferrin Allele Frequencies among Herds of Feral Donkeys in Death Valley National Monument, California
Blake JG, Doulas CL, Thompson LF. 1981. Spatial Variation in Transferrin Allele Frequencies among Herds of Feral Donkeys in Death Valley National Monument, California. Journal of Mammalogy. 62(1):58-63
Serum proteins were studied to clarify interrelationships of seemingly disjunct herbs of feral donkeys (Equus asinus) in the mountains of Death Valley National Monument, California. Sera of 162 donkeys from five localities in the Panamint Mountains were examined by starch-gel electrophoresis to assess polymorphic variation in transferrins. Four homozygous and six heterozygous transferrin phenotypes controlled by four codominant, autosomal alleles were identified with Fe autoradiography. Significant interlocality heterogeneity in genotype distribution and allele frequency distribution among herds was demonstrated. The maximum distance between adjacent herds was 52 km and the minimum distance was 14 km.
