Última Inbreeding evidence in a traditional channel catfish (Ictalurus punctatus) hatchery in Mexico Electron. J. Biotechnol. Parra-Bracamonte,Gaspar Manuel; Sifuentes-Rincón,Ana María; Rosa-Reyna,Xochitl Fabiola De la; Arellano-Vera,Williams; Sosa-Reyes,Brenda. Background: Channel catfish are one of the most important aquaculture species raised for food purposes in Mexico. Two temporal samples were obtained from the largest channel catfish breeding hatchery in Mexico to identify changes in genetic diversity and inbreeding that are promoted by traditional hatchery management. Results: The genetic parameter analysis of 11 microsatellite loci showed no significant change in genetic diversity (p &gt; 0.05). However, a significant heterozygosis deficiency was detected (p < 0.001), and genetic structure analysis indicated moderate differentiation between the temporally divided populations (F ST = 0.08). A moderate level of inbreeding and a slight increase of the inbreeding coefficient from 0.23 to 0.27 were the...

Mol. Biol. Lourenco-Jaramillo,Diana Lelidett; Sifuentes-Rincón,Ana María; Parra-Bracamonte,Gaspar Manuel; Rosa-Reyna,Xochitl Fabiola de la; Segura-Cabrera,Aldo; Arellano-Vera,Williams. DNA from four cattle breeds was used to re-sequence all of the exons and 56% of the introns of the bovine tyrosine hydroxylase (TH) gene and 97% and 13% of the bovine dopamine b-hydroxylase (DBH) coding and non-coding sequences, respectively. Two novel single nucleotide polymorphisms (SNPs) and a microsatellite motif were found in the TH sequences. The DBH sequences contained 62 nucleotide changes, including eight non-synonymous SNPs (nsSNPs) that are of particular interest because they may alter protein function and therefore affect the phenotype. These DBH nsSNPs resulted in amino acid substitutions that were predicted to destabilize the protein structure. Six SNPs (one from TH and five from DBH non-synonymous SNPs) were genotyped in 140 animals; all of...

Garza-Brenner,Estela; Sifuentes-Rincón,Ana María; Rodríguez-Almeida,Felipe Alonso; Randel,Ronald D.; Parra-Bracamonte,Gaspar Manuel; Arellano-Vera,Williams. Abstract We investigated whether a panel of molecular markers previously associated with temperament has an effect on live growth traits. Phenotypic data from 412 Charolais cows categorized according to their age in adult and young cows were used to determine Pearson's correlations between birth (BW), weaning (WW), and yearling live (YW) weight and temperament traits (measured as exit velocity [EV] and temperament score [TS]). For association analysis, selective genotyping of a group of 80 cows identified as the most docile and temperamental were genotyped with a 151-SNP (single-nucleotide polymorphisms) panel of molecular markers previously associated with temperament. Significant Pearson's correlations between birth weight and weaning weight and the two...
