Genetic polymorphism of promoter (Fragment 1, 2 and 3) of prolactin gene in four strains of White Leghorn chicken layers i.e. IWH, IWI, IWK and layer control was identified. Two alleles (A and B) were found in all the promoter fragments of the gene. In above mentioned layer populations, A allele was predominant. The genotypic and allelic distribution was significantly differed among the populations. Different demographic and divergent parameters were estimated in all the lines. It is concluded that all 3 fragments of promoter of prolactin gene was polymorphic in four strains of White Leghorn layer populations.
