Published results were reassessed and original data are provided regarding the origin and relatedness of four postulated chicken breed lineages, egg-type, game, meat-type and Bantam, to each other and to the basic ancestral species of jungle fowls, Gallus gallus. A system approach was employed concerning the planning of the experiments. One element of the system approach is the choice of the breeds to be compared with G. gallus. These breeds were supposed to represent major evolutionary branches of chickens. Four experiments on genetic relationships were conducted using different estimation criteria including morphological discrete characters, body measurements, biochemical markers, and the activity of serum esterase-1. The greatest similarity was found between G. gallus and the egg-type breeds of Mediterranean roots and/or true Bantams. This fact might testify that the indicated chicken groups occupied earlier stages in the evolution from the wild progenitor to the present biodiversity of chickens in the world.
对已发表的结果进行了重新评估，并提供了有关四个假定鸡品种谱系（蛋用型、斗鸡型、肉用型和矮脚鸡型）彼此之间以及与原鸡（Gallus gallus）这一基本祖先物种之间的起源和相关性的原始数据。在实验规划中采用了系统方法。系统方法的一个要素是选择与原鸡进行比较的品种。这些品种被认为代表了鸡的主要进化分支。使用不同的估计标准进行了四项关于遗传关系的实验，包括形态离散特征、身体测量、生化标记以及血清酯酶 -1 的活性。在原鸡与地中海起源的蛋用型品种和/或真正的矮脚鸡之间发现了最大的相似性。这一事实可能证明，上述鸡群在从野生祖先到当今世界鸡的生物多样性的进化过程中处于较早阶段。
