Abstract: The Nile tilapia (Oreochromis niloticus) were collected from six locations in Egypt, Abbassa (Ab) Sharkia, Assute (Asu), Kafer El-Sheikh (Kf) (Lake Brollus), Lake Manzala (Mz), El-Menia (Mn) and El-Qanater El-Khiria (Q). Ten individuals from each population were sampled and dissected. The results revealed that Assute population had the higher similarity with an average (88%) followed by Qanater (87%), El-Menia (86%), Abbassa (84%) and Kafr El-Sheikh (83%) while the Manzala represented the lowest similarity with an average (79%). All population had sex-specific bands in two sexes with the exception of El-Menia population that had only female-specific band and “Q” population that had only male-specific band. Variations among locations herein may be due to spatial isolation across the Nile river and its branches. The diversity within Nile tilapia populations studied in the present work is mainly due to sex polymorphism rather than individual variations and randomly introducing with mismating
