ABSTRACT A total of 80 samples were collected to analyze the mitochondrial DNA (mtDNA) and Y chromosome genetic diversity of two main Portuguese Lidia bovine populations and clarify their genetic relationships with Spanish Lidia lineages. A 521-bp D-loop fragment was sequenced in 40 animals belonging to four herds (three Brava dos Açores and one Casta Portuguesa) and the same number of samples were collected with equal distribution from males in order to genotype six microsatellites, one single nucleotide polymorphism, and […]

The objective of this study was to describe the genetic diversity and structure of the largest Pé-duro population by assessing variation at ten autosomal microsatellite (STR) loci and mitochondrial DNA (mtDNA) sequences. The mean expected heterozygosity was 0.755, the mean observed heterozygosity was 0.600 and significant inbreeding coefficient (Fis) and deviations from the Hardy-Weinberg equilibrium in most of analyzed loci demonstrate the impact of inbreeding and homozygosis on this population. A more in-depth genetic analysis could be achieved by expanding […]
