Title
Lack of genetic variation in developmental instability in zebra finch (**Taeniopygia guttata**) wing and tarsus
Author
Abstract
Question: How much additive genetic variance of developmental instability is maintained under a selectionmutation balance in a domesticated population of zebra finches (Taeniopygia guttata)? Methods: We estimate the heritability and coefficient of additive genetic variance (CVA) of wing and tarsus developmental instability from an animal model. Results: No significant additive genetic variance was detected. Estimates of additive genetic variance, heritabilities, and CVA were low, but, in contrast to the CVA, moderate heritabilities could not be excluded due to highly skewed distributions. Conclusions: Although domesticated for more than 100 years, reducing selection pressures, lowering genetic variation for developmental instability, and allowing the accumulation of de novo genetic variance, the CVA of developmental instability is likely to be below 23% in this population.
