“…Those inherited as recessives on the Z chromosome include cerebellar hypoplasia (Winterfield, 1953 ;Markson et al 1959), comatose (Goodwin et al 1950, gasper (Price et al 1966), jittery (Bohren, 1950;Godfrey et al 1953), paroxysm (Cole 1958Kuenzel and Rubenstein, 1974) and shaker (Scott et al 1950;Mueller, 1952). Mutants inherited as recessives on the autosomes include congenital loco (Knowlton, 1929 ;Hutt, 1949), congenital tremor (Hutt and Child, 1934), crazy (McGibbon, 1973), epilepsy (Crawford, 1969;Ookawa, 1977), pirouette (McGibbon, 1974) and tipsy (Hawkes et al 1973).…”

“…This variation may be due to the genetic background of the individual, environmental factors, and a combination of both. Kuenzel and Rubenstein (1974) and Ookawa (1977) examined physiological mechanisms involved with paroxysm and epilepsy, respectively. Deterioration of Purkinjie cells of the cerebellum appears to be associated with shaker (Scott et al 1950) and jittery (Godfrey et al 1953) Overall, however, little is known about the pathways by which behavioural mutants cause phenotypic changes in the fowl.…”

The various behaviours exhibited by the Jungle fowl were instrumental in the initial domestication of the chicken which occurred during the Neolithic period. Since then, there has been concern with how various populations of chickens respond in different environments. These concerns include behaviour-genetics, as well as the other disciplines involved in the biology of the fowl.No attempt has been made to be encyclopaedic in this paper; rather, to have selected topics that provide an overview of the field as it relates to the chicken. The publications cited were selected from a much larger list within topical areas and readers interested in the behaviour of chickens per se, may find them in the general reviews of Wood-Gush (1971) andFischer (1975). Although no comparable recent publications on either the genetics of chickens or an interfacing of genetics and behaviour in the fowl are available, there have been attempts to provide a general overview of behavioural genetics (eg. Ehrman and Parsons, 1976;Fuller and Thompson, 1978).In an earlier publication (Siegel, 1970), it was pointed out that the combination of the disciplines of genetics and behaviour assumes an awareness of genetics of populations and the behaviour of individuals and populations. Genetically, there is also concern with differences in behavioural phenotypes among individuals in the population. As with morphological and physiological traits, the phenotypic expression of a behaviour is dependent on the genetic background, the environment, and the interplay of heredity and environment. Furthermore, prior experiences are complicating factors in studying behaviours, and caution must be exercised to minimize confounding from these sources. DomesticationDomestication results in a situation wherein the breeding, care and feeding of animals are, to some degree, subject to continuous control by man (Hale, 1962). Darwin (1875) suggested that domestic animals were modified through unconscious selection long before man selected for specific traits. He had noted earlier (Darwin, 1858) that domestication involved breeding in captivity, was goal oriented in an economic sense, and resulted in the disuse of certain naturally adapted features. 9 10

“…Previous evidence from behavioral and electroencephalographical investigations of birds with seizures (induced pharmacologically or genetically) has led to the recognition that epilepsy is present in avians and that these seizures suggest many similarities between mammalian and avian epilepsies [17]. Recent studies have demonstrated that Gallus gallus have a sudden death syndrome (SDS), characterized by loss of balance, violent flapping, and strong muscular contractions [18].…”
