Abstract
The behavioral mutant "back-drawer" of Japanese quail is characterized by crouching and back-drawing action with the neck bending ventrally and occasional forward rolling. The abnormal behavior appears from hatching to 8 weeks of age. Back-drawers were classified into three types: those showing the abnormality at hatching and dies within 5 days; those showing the abnormality after 2 weeks of age and dies shortly thdreafter; and long survivors suffering from abnormal behavior, and showing gradual recovery. Back-drawer males are infertile when showing the abnormality, but can produce progeny after recovery. In contrast, the females tend to have a short life span and lack reproductive ability. Genetic analyses have indicated that this mutant character is controlled by 2 pairs of autosomal recessive genes.This publication has 0 references indexed in Scilit:
