Abstract:
Seven primers of randomly amplified polymorphic DNA (RAPD) were selected to study
the genetic variations among 14 individuals of goat (Capra hircus) from two domestic
Sudanese goat breeds (Nilotic and Nubian). The test generated 59 entirely repeatable
RAPD fragment bands and the statistical analysis showed 55 polymorphic bands among
the 14 individuals. The genetic distances among the population range from 41to 28.
The highest dissimilarity coefficient was between individuals within the Nilotic breeds
while there was a comparatively low degree of differentiation among the Nubian
population. The constructed UPGMA dendrogram of the coefficient of similarity
showed that the Nubian clustered together while the individuals from the Nilotic form 4
groups. It was clearly seen that the link between the individual of the Nilotic is quite
weak and some of them linked to the Nubian. The results of the study offer useful
information about some Sudanese goat breeds
