Associations between some characteristics of fitness (the age of the first reproduction, life span, fertility, and number of missed pregnancies) and heterozygosity for some allozyme loci have been studied in a population of the sable Martez zibellinna L. kept in cages at a farm. Of all fitness characteristic studied, a weak correlation has only been found between heterozygosity and the age of the first reproduction (maturation rate). The age of the first reproduction is positively associated with the life span and fertility. The results obtained are discussed in terms of the relationship between the genetic variation of longevity and developmental rate and prospects of their application to breeding practice.
在一个饲养于农场笼舍中的紫貂（Martes zibellina L.）种群中，研究了某些适应性特征（首次繁殖年龄、寿命、生育力和未孕次数）与一些等位酶位点杂合性之间的关联。在所有研究的适应性特征中，仅发现杂合性与首次繁殖年龄（成熟率）之间存在微弱关联。首次繁殖年龄与寿命和生育力呈正相关。根据长寿和发育速率的遗传变异之间的关系及其应用于育种实践的前景，对所得结果进行了讨论。
