The study investigated the polymorphism of myxovirus resistance (Mx) gene in four Nigerian chicken genotypes. A total of 200 chickens comprising of 50 Normal feathered, 50 Frizzle feathered, 50 Naked neck, and 50 Noiler chickens. The chickens were kept for 16 weeks during which feed and water were given ad libitum. Other management practices were carried out. Blood samples were collected from the chickens via the wing vein using 2ml syringe into an EDTA bottle for DNA extraction. Polymerase Chain Reaction (RCR) was carried out using the DNA extracted and primers of Mx gene. PCR amplicons were sequences and sequences subjected to analysis. Results obtained showed the highest genetic distance is between the Frizzled feather and Naked neck (0.1537) and the least is between the Noiler and the Normal feather (0.0755). Nucleotide diversity with JC (PiJC) obtained for Normal feathered, Naked neck, Noiler and Frizzled feather genotype were 0.01005, 0.05868, 0.01973 and 0.17961. Gst value obtained (0.04437) indicated that 95.56% genetic variation within populations and only 4.44% between populations. The estimated Nm value (5.38) suggested genetic differentiation among populations of Nigerian chicken genotypes impeded by high gene flow. This could be further supported by the result obtained in the genetic distance which suggested relatedness among the chicken populations studied.
