Y-STR INRA189 polymorphisms in Chinese yak breeds

Y-STR INRA189 polymorphisms in Chinese yak breeds.

To further explore Y-STR INRA189 polymorphisms in the yak, and to determine the genetic differences among yak breeds, genotyping analysis of INRA189 in 102 male yak individuals from three yak breeds in Qinghai Province of China was performed. Genotyping revealed the presence of four alleles, with sizes of 149, 155, 157, and 159 bp, respectively. Of these, the 157-bp allele, which was found with...

Y chromosomal STR polymorphism in northern Chinese populations.

Y chromosomal STRs show sufficient variability among individduals in a population and a high degree of geographical differentiation, such that their polymorphic character makes them especially suited for population genetic studies. To investígate the polymorphism of a set of 17 Y-STR loci in northern China, we genotyped the 17 Y chromosomal STR loci in a population sample of 377 unrelated males...

Duplication polymorphisms in exon 4 of κ-casein gene in yak breeds/populations.

The objective of this study was to compare 12 bp-duplication polymorphisms in exon 4 of the κ-casein gene among 3 breeds/populations of yak (Bos grunniens). Genomic DNA was extracted from yak blood or muscle samples (N = 211) and a partial sequence of exon 4 of κ-casein gene was amplified by polymerase chain reaction. A polyacrylamide gel electrophoresis assay of the products (169 bp) revealed ...

Y-chromosomal Binary Haplogroups in Japanese Population and their Relationship to 16 Y-STR Polymorphisms

Y-chromosomal binary haplogroups in the Japanese population and their relationship to 16 Y-STR polymorphisms.

We investigated Y chromosomal binary and STR polymorphisms in 263 unrelated male individuals from the Japanese population and further examined the relationships between the two separate types of data. Using 47 biallelic markers we distinguished 20 haplogroups, four of which (D2b1/-022457, O3/-002611*, O3/-LINE1 del, and O3/-021354*) were newly defined in this study. Most haplogroups in the Japa...
