| Abstract: | Reindeer were introduced into Alaska 100 years ago and have been
maintained as semidomestic livestock. They have had contact with wild
caribou herds, including deliberate cross-breeding and mixing in the
wild. Reindeer have considerable potential as a domestic animal for
meat or velvet antler production, and wild caribou are important to
subsistence and sport hunters. Our objective was to quantify the
genetic relationships of reindeer and caribou in Alaska. We
identified allelic variation among five herds of wild caribou and
three herds of reindeer with DNA sequencing and restriction enzymes
for three loci: a DQA locus of the major histocompatibility complex
(Rata-DQA1), k-casein and the D-loop of mitochondrial DNA. These loci
are of interest because of their potential influence on domestic
animal performance and the fitness of wild populations. There is
considerable genetic variation in reindeer and caribou for all three
loci, including five, three and six alleles for DQA, k-casein and
D-loop respectively. Most alleles occur in both reindeer and caribou,
which may be the result of recent common ancestry or genetic
introgression in either direction. However, allele frequencies differ
considerably between reindeer and caribou, which suggests that gene
flow has been limited. |
