The anatomical structure of phonation in the domestic chicken Gallus gallus (red jungle fowl, forma domestica) of both sexes was studied to determine sex variations in structures. Ten (10) birds, involving 5 males and 5 females were obtained from a local market for student demonstrations and used for this study. Tracheal rings were observed to be made of circular cartilages numbering thirty and above with the distal most (1/5) tracheal rings narrowed, calcified and fused as the tympanum making part of the Syrinx. The rings become calcified and somewhat collapsed through the bronchial bifurcations. When squeezed, the trachea collapsed completely between fingers but could at releasing the fingers be raised up due to elastic components separating the rings from one another. Other structures involved in vocalization includes straps of muscles. Male structures involved in respiration and vocalization were well formed compared to those of the female. Both tracheobronchialis lateralis and ventralis muscles were thicker than those of the female. Male tracheobronchialis ventralis and dorsalis muscles were well formed and spindle shaped. However, the female tracheobronchialis muscles were seen to be wider compared to the male. The vocal organs (voice box) were seen to be arbitrarily triangular in structure at the bifurcation of the trachea in both sexes. The male Syringeal walls were thinner and were seen to have marked inter Pessula space. The Pessulus mark an abrupt change from the circular trachea to strongly elliptical entrances to the bronchi. It was concluded that the differences in the thinness of syringeal walls coupled with differences between the males and females in other tracheal muscles might be responsible for the stronger vocalization in the male.

The present investigation was conducted to study the morphology, production potential and genetic architecture of Red Jungle Fowl (Gallus gallus) kept in captivity. Records of 104 birds of RJF (65 males and 39 females) were utilized in study. Males had prominent plumage pattern with neck hackles, greenish black tails, and prominent bright red single comb, while females were comparatively smaller with very small combs. RJF are seasonal breeder having small clutch and egg size. Observed and effective number of alleles across the microsatellite loci varied from 5-18 with an overall mean of 10.28 and 5.04, respectively. The average expected heterozygosity and observed heterozygosity were 0.492 and 0.758 respectively. Study revealed existence of population structure accompanied by higher inbreeding along with sufficient heterozygosity. The effort must be directed to introduce unrelated typical RJF in to the present population to maintain heterozygosity and ensure conservation of unique germplasm.
