Transmission of C-band variants in Japanese quail

Abstract

Heteromorphisms of chromosome banding patterns can be useful markers for gene mapping and other kinds of genetic studies. In Japanese quail, the centromere region of chromosome No. 4 is the site of a heteromorphism. One form of the C-band at this region is relatively small(`a` form); an alternative form is much larger(`b` form). To identify the transmission patterns, all possible matings were made between birds with karyotype a/a, a/b, and b/b. The outcome from all crosses are entirely consistent with the expectation from simple Mendelian transmission. No evidence was found for segregation distortion or gametic selection. This dimorphism, therefore, is a reliable marker.
