| Abstract: | Associations between some characteristics of fitness (the age of the first reproduction, life span, fertility, and the number of missed pregnancies) and heterozygosity for some allozyme loci have been studied in a population of the sable Martes zibellina 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. |
