| This study estimated the genetic diversity and structure of 12 genetic groups (GG) of locally adapted and specialized pigs in the state of Pernambuco using 22 microsatellite markers. Nine locally adapted breeds (Baé, Caruncho, Canastra, Canastrão, Mamelado, Moura, Nilo, Piau and UDB (Undefined Breed)) and 3 specialized breeds (Duroc, Landrace and Large White), totaling 190 animals, were analyzed. The Analysis of Molecular Variance (AMOVA) showed that 3.2% of the total variation was due to differences between genetic groups, and 3.6% to differences between local and commercial pigs. One hundred and ninety eight alleles were identified and apart from the Large White breed, all GG presented Hardy-Weinberg Equilibrium deviations for some loci. The total and... |

| Researches on genetic relationships among water buffalo populations are useful in supporting conservation decisions and designing of breeding schemes. The aim of this study was to assess the genetic relationships among Cuban Buffalypso/Carabao hybrids and Murrah and Jaffarabadi Brazilian buffaloes using nine cattle microsatellite markers. During the analysis, four loci were excluded due to the presence of null alleles, stuttering and gametic disequilibrium. Mean numbers of alleles and the heterozygosities observed and expected in the three populations were not significantly different. Heterozygosities found were above 60%. All five loci were in Hardy-Weinberg equilibrium. Wright´s index for estimating inbreeding were negative in the three populations. A... |
