Abstract :

The chromosomal analysis of five species of order Perciformes, species Cheilinus lunulatus, Cheilinus abudjubbe, Cheilinus mentalis, Cheilinus digrammus and Cheilio inermis were carried out; all samples were collected from Hurghada, on the Egyptian Red Sea coast. The diploid chromosome numbers and Fnumental numbers for five species under study were 2n=40 and FN=54, 2n=40 and FN=54, 2n=44 and FN=60, 2n=40 and FN=52 and 2n=48 and FN=66 respectively, they were different in their karyotypes,. The RAPD–PCR analysis was carried out on species under studies by using eight primers. All eight primers amplified successfully on the genomic DNA extracted from all studied fish species. Using RAPD–PCR is very useful in determination genetic molecular variations and relationship degree between the species which belong to same family
