Chickens and Dukes

CoRR, 2021
Following on the King Chicken Theorems originally proved by Maurer, we examine the idea of multiple flocks of chickens by bringing the chickens from tournaments to multipartite tournaments. As Kings have already been studied in multipartite settings, notably by Koh-Tan and Petrovic-Thomassen, we examine a new type of chicken more suited than Kings for ...

Cloning in Chickens

Poultry Science, 1971
Abstract Briggs and King (1952) perfected a method for transferring nuclei of embryonic cells into enucleated eggs of the frog. Gurdon (1960) described a method by which he obtained many genetically identical frogs by the direct and serial transplantation of the nuclei of dissociated endoderm cells to the enucleated eggs of a single female. The cells
