Genetic Analysis of Nigerian Indigenous Goat Populations Using Microsattelite Markers
This study was conducted to determine the genetic relationships among and population history of four Nigerian indigenous goat populations. A total of 200 goats from three breeds namely Sahel (60), Red Sokoto (60), West-African dwarf (60) and Kano Brown, a strain (20), were used for the study. Tissue samples were collected from the ear of animals using an Allflex® ear punch tissue sample collect...
متن کاملGenetic and Phenotypic Differentiation of Qualitative Traits in Nigerian Indigenous Goat and Sheep Populations
Data from smallholder flocks of adult West African Dwarf (WAD) and Red Sokoto goats (n = 824) and Yankasa, Uda and Balami sheep (n = 636) were utilized to investigate the distribution and frequencies of certain qualitative traits. The animals were randomly sampled in Northern parts of Nigeria. They were scored for the presence or absence of wattle, beard, horn, coat colour [Phaeomelanic standar...
متن کاملGenetic Differentiation of Draa Indigenous Breed and Relationships with Other Goat Populations Assessed by Microsatellite DNA Markers
Moroccan goats are characterized by the presence of different populations identified only based on their phenotypes. The objectives of this study were to assess the genetic differentiation of the Draa goat breed and to analyze its genetic structure and its relationships with other local populations using 12 microsatellite markers. The screening was done in South Eastern and Southern Morocco on ...
متن کاملGenetic variation of three commercial and three indigenous goat populations in South Africa
_______________________________________________________________________________________ Abstract Three commercial and three indigenous goat populations from South Africa were studied for genetic variation using ten microsatellite markers. Heterozygosity values of between 0.62 and 0.69 were obtained for the populations, except for the SA Boer Goat, which had the lowest variation (0.49). Genetic ...
متن کاملEffect of mutation on genetic differentiation among nonequilibrium populations.
The usefulness of GST and similar measures of genetic differentiation has been questioned repeatedly because of their dependence on the amount of heterozygosity within populations, creating problems when comparing degrees of divergence at loci with different mutation rates. Although the effect of mutation on GST is expected to be small in the early phases of divergence, it is unclear for how lo...
