Inbreeding components of body weight and growth rate in Japanese Quail.
1. The parental inbreeding component of body weight and daily gain was partitioned into paternal and maternal inbreeding components and the latter were found to be the mor important. 2. The contribution of the maternal inbreeding to the depression of characters was more pronounced on 1-d-old chicks, but declined as the chicks grew. 3. The body weight taken near sexual maturity showed a low and non-significant decline. 4. In spite of differences in the body weight of the two populations of Japanese quail the inbreeding components were similar.
