Abstract

Genetic variability at 36 loci was studied in white-tailed deer (Odocoileus virginianus) populations, on the Savannah River Plant (SRP) in South Carolina. Mean multilocus heterozygosity (H), percentage of polymorphic loci (P) and average number of alleles per locus (A) for white-tailed deer were calculated and compared with values for white-tailed deer from several locations (SRP deer: H = 9.9 per cent, P0.05 = 30.6 per cent, A = 1.89; white-tailed deer overall: H = 10.4 per cent, P0.05 = 32.3 per cent, A = 1.94). Frequency distributions for single locus heterozygosity values (h) and the number of alleles per locus for white-tailed deer were found to be significantly different from those of mammals in general. Analysis of single-locus data based on quaternary structure and functional groups of proteins failed to demonstrate expected differences as predicted from the literature. White-tailed deer have a high level of heterozygosity, but they do not exhibit many of the life history and environmental characteristics associated with high heterozygosity in other animals.

摘要

在南卡罗来纳州的萨凡纳河工厂（SRP）对白尾鹿（Odocoileus virginianus）种群的36个基因座的遗传变异性进行了研究。计算了白尾鹿的平均多位点杂合度（H）、多态位点百分比（P）和每个基因座的平均等位基因数（A），并与来自几个地点的白尾鹿的值进行了比较（SRP鹿：H = 9.9%，P0.05 = 30.6%，A = 1.89；总体白尾鹿：H = 10.4%，P0.05 = 32.3%，A = 1.94）。发现白尾鹿单基因座杂合度值（h）和每个基因座等位基因数的频率分布与一般哺乳动物的频率分布有显著差异。基于蛋白质的四级结构和功能组对单基因座数据的分析未能证明文献中预测的预期差异。白尾鹿具有较高水平的杂合度，但它们没有表现出许多与其他动物高杂合度相关的生活史和环境特征。
