Abstract:

Seventeen microsatellite loci were used to identify the phylogenetic relationship among four Egyptian breeds and one Spanish line of rabbits. A total of 114 bucks rabbits belonging to four Egyptian breeds -Black Baladi (EBB), Gabali (EG), Red Baladi (ERB) and White Giza (EWG)- and Spanish White New Zealand line from Universidad Politécnica de Valencia (NZW) were studied. All microsatellite loci typed were polymorphic. The average number of alleles per locus was 5.41, ranging from 2 to 12. A total of 16 private alleles were found in 7 out of 17 microsatellite loci used. Mean observed heterozygosity was 0.527, ranging from 0.477 in the NZW breed to 0.581 in the EWG. Lower values for Ho were found for all populations. The inbreeding coefficient of individuals relative to the total population (FIT) was 0.279. The overall within-population heterozygote deficit (FIS) was 0.165, ranging from 0.045 in NZW breed to 0.266 in EBB breed. The overall variation between population (FST) was 0.137, where the NZW breed showed the most differentiated population (FST = 0.194). The Neighbour-Joining tree of the Reynolds genetic distances (DR) among populations shows a clear separation of the Spanish population (NZW) from the Egyptians breeds and there is a population mixture in the Egyptian populations. Only the ERB may to cluster in one independent population.
