Protein polymorphism in the egg albumen of red grouse (L. Lagopus scoticus)

Egg albumen of red grouse was separated by electrophoresis and then stained with naphthalene black. The number of dark-blue bands seen in one zone varied from three to six. The four fastest bands were probably controlled by three codominant alleles at an autosomal locus. The pattern of inheritance of the second fastest band was not clear because the sample was small.
