Genetic diversity of ten Egyptian chicken strains using 29 microsatellite markers

In this study, we assessed the genetic diversity of three Egyptian local chicken strains (Fayoumi, Dandarawi and Sinai) and six synthetic breeds derived from Fayoumi and Sinai by intercrossing with Barren Plymouth Rock, Rhode Island Red or White Cornish. Diversity measures were based on interrogation of 29 microsatellites. We identified three main clusters of chicken populations encompassing selected Fayoumi lines and Doki-4 (cluster-1), native Dandarawi (cluster-2) and Sinai, and all six synthetic breeds (cluster-3). Dandarawi and Fayoumi lines exhibited lower intra-population genetic diversity and allelic privacy than Sinai and synthetic breeds. The global inbreeding (F(IT) ) was 0.11, among-population differentiation (F(ST) ) was 0.07, and within-population differentiation (F(IS) ) was 0.04. The between-population marker-estimated kinship was lower than within-population estimates. The cluster analysis classified the Fayoumi lines, Dandarawi and Gimmizah as clearly separated populations. The other strains were configured in mosaic admixed groups
