ABSTRACT The objective of this study was to assess the genetic structure and diversity of six Santa Inês sheep flocks from the Central-Northern Brazil. A panel of 20 highly polymorphic and informative microsatellite loci was selected and amplified. The following parameters were obtained: overall mean of number of alleles = 15.4; expected heterozygosity (He) = 0.89; polymorphism information content (PIC) = 0.88; discriminatory capacity = 0.95; combined probability of identity = 1.50 × 10−34; and probability of exclusion = 1.00.

The objective of this study was to characterize the genetic variability of Anglo-Nubian goats using microsatellite markers. The study was conducted using herds from four municipalities of Central-Northern Piauí (Teresina, José de Freitas, Campo Maior, and Angical), where technical information is scarce. Seven markers suggested by FAO were used (ILSTS11, McM527, INRA23, ETH10, OarfCB304, OarfCB48, and MAF209). The samples were genotyped using a 7% polyacrylamide gel. The average number of alleles per locus was 4.0, with observed and expected heterozygosity […]

The aim of this research was to describe the genetic structure of the Brazilian Red Sindhi breed using pedigree records from registered animals born from 1955 to 1998. The data file was separated in the following periods: 1979-1983, 1984-1988, 1989-1993 and 1994-1998. The total inbreeding increased from 0.38 to 10.13%, the expected inbreeding under random mating increased from 0.07 to 5.65%, and the inbreeding due to population subdivision increased from 0.30 to 4.74%, from the first to the final period, […]
