The dichotomy structure of Y chromosome Haplogroup N
Haplogroup N-M231 of human Y chromosome is a common clade from Eastern Asia to Northern Europe, being one of the most frequent haplogroups in Altaic and Uralic-speaking populations. Using newly discovered bi-allelic markers from high-throughput DNA sequencing, we largely improved the phylogeny of Haplogroup N, in which 16 subclades could be identified by 33 SNPs. More than 400 males belonging t...
متن کاملPhylogeography of the Y-chromosome haplogroup C in northern Eurasia.
To reconstruct the phylogenetic structure of Y-chromosome haplogroup (hg) C in populations of northern Eurasia, we have analyzed the diversity of microsatellite (STR) loci in a total sample of 413 males from 18 ethnic groups of Siberia, Eastern Asia and Eastern Europe. Analysis of SNP markers revealed that all Y-chromosomes studied belong to hg C3 and its subhaplogroups C3c and C3d, although so...
متن کاملCHROMOSOME COUNTS IN SOME MOSSES OF IRAN
Cytological information is absolutely lacking for the Iranian moss flora (Bryophytes). The present research, dealing with cytological studies on the following five species (including two expressions and one variety) of Iranian mosses, namely, Amblystegium riparium (Hedw.) B.S.G. “brevipes” expression(n=20), A. riparium (Hedw.) B.S.G. “pennellii” expression (n=9, 9+m, 9+2m), A. serpens (Hedw.) B...
متن کاملP-17: Body Mass Index and Sperm Counts Associated with Varicocele in Infertile Men
Background: Varicocele is a progressive disease and etiology of varicocele is not well known. Some studies have been reported that prevalence of varicocele decreases with increasing BMI. The aim of this study was to determine interrelation of varicocoele with height, body mass index (BMI) and sperm counts in infertile men. Materials and Methods: We retrospectively evaluated the data of all pati...
متن کاملO-7: Y Chromosome Microdeletions Are Not Associated with Spontaneous Recurrent Pregnancy Loss in A Sinhalese Population in Sri Lanka
Background: Many advances have been made in reproductive medicine yet the spontaneous loss of a pregnancy remains the most common complication of pregnancy. The aetiology of spontaneous recurrent pregnancy loss (RPL) is multifactorial. Y chromosome microdeletions are found in approximately 7% of men with low sperm counts and, compared to the general population, a higher frequency of spontaneous...
