Abstract
Telomere DNA length exhibits an age-related decline in humans and it is emerging as a potential biomarker for longevity and fitness. As telomere DNA length in humans is a heritable trait, we assessed whether variation in telomere DNA length in sheep correlated with Australian Sheep Breeding Values (ASBVs) for a range of production traits. The genetic relationship between telomere length and ASBVs was generally low, with the highest associations observed for birth weight (0.14), fatness (-0.14; CFAT) and two wool quality traits; staple strength (-0.1) and coefficient of variation in fibre diameter (0.15).
