Description NorthAfrican
countries are endowed with a wealth of sheep resources adapted to a wide range
of environments and production systems. In this study, genetic diversity was estimated in seven
sheep breeds, including two Algerian (Hamra n=35 and OuledDjellal
n=50) and two Moroccan
(BéniIghil
n=50 and D’men n=49) local breeds as well as two French (Corse n=50 and Lacaune
n=50) and one subSaharan
(ForoForo
n=46) breed, using six microsatellite markers.
All markers were highly informative and a total of 109 alleles were detected with a proportion
of private alleles of 0.023. Observed heterozygosity average over loci was 0.66 ± 0.195. The
estimated withinpopulation
inbreeding FIS was significant in all studied breeds. 6.1% of the
genetic diversity in the total population could be attributed to differences among the breeds.
Significant gene flow among NorthAfrican
breeds was detected. Population structure analysis
revealed showed that all African breeds are closely related and were distinguished in the same
cluster; however, the European breeds belonged to a different cluster.
