INHERITANCE OF SHELL COLOR AND ADDUCTOR MUSCLE COLOR IN CHLAMYS NOBILIS
华贵栉孔扇贝(Chlamys nobilis)壳色与闭壳肌颜色遗传规律的研究

The shell color and adductor muscle color of Chlamys nobilis were polymorphic, of which the yellow shell color and adductor muscle color ownimportant economic value due to their being the target traits for breeding. Study on the inheritance of these colors can lay theoretical foundation for the selective breeding of these two traits. Reciprocal crossings and Chi-square test were used to study the inheritance of shell color (orange and brown) and adductor muscle color (yellow and white) for C. nobilis. The results showed that the shell color and adductor muscle color of C. nobilis were qualitative traits which were controlled by genes and heritable independently of environmental effect. Orange was dominant over brown for the shell color and white adductor muscle was also dominant over yellow. The shell color and adductor muscle color were not linked and not affected by maternal effect. All individuals with brown shell or yellow adductor muscle color were recessively homogeneous, the traits of their offspring were all the same as their parents. Because those individuals with orange shell or white adductor muscle color may be dominantly homogeneous or heterogeneous, the attainment of dominant homogeneous family lines should be realized only by selecting those lines built for 2 generations.
