“…This result is attributed to commercial trade that occurred during the colonial period and several animal introductions in Brazil over the years (Ribeiro et al, 2004). The results of the Canindé analyses are supported by the broad distribution of the A lineage, which is dominant throughout the world (Sultana et al, 2003;Naderi et al, 2007;Benjelloun et al, 2011;Zhong et al, 2013;Wang et al, 2015;Lopes et al, 2016;Kadowaki, et al, 2016;Kibegwa et al, 2016).…”

“…Our sample of 179 goats included 29 distinct haplotypes, with a haplotype diversity of 0.820, a value higher than the values obtained for Crespa goats (0.740) studied by Lopes et al (2016) and lower than that observed by Liu et al (2007) in Chinese goats (0.930). Haplotype diversity was high for each subpopulation (Table 1), ranging from 0.562 (Boa Vista-PB, PBB) to 0.900 (Lajes-K, RNL1).…”

“…Oliveira (2007) analyzed a 130-bp fragment of the same mitochondrial region in 1531 sequences and found 55 polymorphic sites in goats from northeastern Brazil. Studies on goats from the Brazilian Crespa ecotype (Lopes et al, 2016), Portuguese goats (Pereira et al, 2005), Mediterranean goats (Hughes et al, 2012), Chinese goats (Zhong et al, 2013;Zhao et al, 2014), African goats (Kibegwa et al, 2016;Kadowaki et al, 2016), and goats of different regions worldwide (Naderi et al, 2007) were presented. The fragments of the D-loop region utilized in these studies varied from 130 to 696 bp, with 24 to 118 polymorphic sites.…”

“…These early studies constituted the basis for more specific regional studies. Oliveira (2007) analyzed a fragment of the D-loop region in goats from northeastern Brazil and Lopes et al (2016) performed studies on Crespa ecotypes in southern Brazil, and the haplogroup A was predominant in the studied ecotypes. Haplotypes from Brazilian goat breeds are phylogenetically close to haplogroup A, which represents more than 90% of haplotypes worldwide (Taberlet et al, 2011) and has been widespread across the globe.…”

ABSTRACT. The success of the geographical distribution of goat populations around the world is a consequence of the adaptive potential of these breeds. Several relevant traits to the success of the species in colonizing different ecosystems (and use by man) evolved before domestication. These features were relevant for the selection of different breeds. Each breed represents a genetic heritage that may be unique and essential for maintaining the species. The objective of this study was to catalog the mtDNA haplotypes of the Brazilian autochthonous Canindé goat breed and to characterize the genetic diversity observed in subpopulations by sequencing a 481-bp fragment corresponding to the first portion of the control region in 178 individuals from 10 herds, sampled in six Brazilian states. The global population displays a total of 29 haplotypes and 56 polymorphic sites. About one-third (10) of the haplotypes were common to all subpopulations while the remaining (19) were exclusive to a single subpopulation. The population exhibited high average haplotype diversity (0.82), with maximum and minimum values of 0.90 and 0.56 in individual subpopulations, respectively. In contrast, nucleotide diversity was 0.014, with maximum and minimum values of 0.020 and 0.004, respectively. The spatial analysis of molecular variance did not detect structure within the Canindé goat breed, and analysis of molecular variance revealed that 88.4% of the variation observed in the population was due to differences among individuals in the same subpopulation. Only 11.4% of the genetic variation referred to differences among subpopulations. About one-third (33.1%) of the individuals within population shared the same haplotype, which may be due not only to the breed developing from a small number of matrilines. The Brazilian autochthonous Canindé breed was classified as haplogroup A, a haplotype predominant in the Europe region.

“…These estimates, however, are higher than what has been reported between Alpine and Saanen dairy goats and the naturalized Brazilian Moxotó breed (Araújo et al, 2006), between Brazilian naturalized, exotic purebreds and crossbred goats (Oliveira et al, 2007), and between locally adapted Crespa goats and the phenotypically similar Angora breed (Lopes et al, 2016).…”

Genetic diversity and relatedness between Canindé and British Alpine goat breeds in Northeastern Brazil accessed by microsatellite markers

et al. 2017

ABSTRACT. The aim of this study was to access the genetic diversity and relatedness between Canindé and British Alpine goat breeds in the States of Piauí and Ceará using microsatellite markers. Genomic DNA was isolated from hair samples of 99 goats belonging to six different flocks. A panel of polymorphic heterologous microsatellite loci was used to genotype individuals. The microsatellite markers resulted in a total number of 145 alleles, with an average of 8.5 alleles per locus. The observed and expected heterozygosities were ≥0.687 and ≥0.627, respectively, for all loci. The polymorphic information content showed that all loci were highly informative with an overall mean of 0.757. Overall F ST across all populations and loci was 18%, which was consistent with the coefficient of gene differentiation (G ST = 0.104). AMOVA revealed that 12.8% of the variation was captured between breeds. The Bayesian STRUCTURE clustering detected the maximum likelihood for a model of two genetically distinct groups, in agreement with the number of predefined studied breeds and the two-dimensional plot from the PCoA analysis. The exotic British Alpine breed and the naturalized Brazilian Canindé breed were clearly differentiated by the microsatellite markers, indicating that these two breeds have distant genetic identities, despite the phenotypic similarity.
