Disc electrophoresis of serum proteins was conducted for the peafowl, guineafowl, peafowl-guineafowl hybrid, and domesticated chicken. The four birds analyzed are of the same order but family status has been questioned. Serum protein patterns for all birds were similar in the anodic regions but different in the cathodic regions. The peafowl-guineafowl hybrid showed a pattern more similar to that of the peafowl than to that of the guineafowl. In morphologic characters the hybrid also was more similar to the peahen than to the guineafowl. In the cathodic region the serum protein pattern of the guineafowl was more unlike the patterns of the other three birds.
