Abstract

The domestic chicken Gallus gallus domesticus belongs to the poultry species, from the order Galliformes and the family Phasianidae. The maternal ancestor of the domestic chicken is recognised from the domestication of the Red Junglefowl G. Gallus originated of Southeast Asia (Lawal et al., 2020; Parkhurst & Mountney, 1988; Laatsch, 2022). G. Gallus domesticus, by definition, refers to birds kept in captivity to produce products of economic value. In other words progress and selection means leads to say that G. Gallus are bred mainly for their meat and for their eggs (Parkhurst & Mountney, 1988). Generation by generation, selection for certain characteristics, such as physical properties, led to the development of varieties (Laatsch, 2022).
