Allelic frequencies

Allelic frequencies and statistical data obtained from 15 STR loci in a population of the Goiás State

T. C. Vieira, Silva, D. M., Gigonzac, M. A. D., Ferreira, V. L., Gonçalves, M. W., and da Cruz, A. D., Allelic frequencies and statistical data obtained from 15 STR loci in a population of the Goiás State, vol. 12. pp. 23-27, 2013.

Due to the miscegenation of the Brazilian population, the central region of Brazil was colonized by internal migration of individuals from different origins, who contributed to the genetic diversity existing in this population. The purpose of this study was to estimate population parameters based on the allele frequencies for 15 polymorphic autosomal short-tandem repeat (STR) loci present in the population of the State of Goiás in the central region of Brazil, and to compare the results with those of others from different Brazilian populations.

Lack of an association between a single nucleotide polymorphism in the bovine myogenic determination 1 (MyoD1) gene and meat quality traits in indigenous Chinese cattle breeds

J. A. Ujan, Zan, L. S., Wang, H. B., Ujan, S. A., Adoligbe, C., Wang, H. C., and Biao, S. F., Lack of an association between a single nucleotide polymorphism in the bovine myogenic determination 1 (MyoD1) gene and meat quality traits in indigenous Chinese cattle breeds, vol. 10, pp. 2213-2222, 2011.

The myogenic determination 1 (MyoD1) gene is a member of the MyoD gene family. It encodes for skeletal muscle-specific transcription factors containing highly conserved basic helix-loop-helix regions that perform important roles in the initiation, maintenance, and regulation of phenotypic traits. We investigated a new single nucleotide polymorphism (SNP) in the MyoD1 gene to evaluate whether this polymorphism affects meat quality traits in five Chinese indigenous cattle breeds, namely Qinchuan (QC), Xia-Nan (XN), Nan-yang (NY), Luxi (LX), and Jia-xian red (JXR).
