Ychromosome, etc ; DNA; comparative study; crime; females; loci; males; India; Show all 8 Subjects
Abstract:
... In forensics, DNA plays an important role to link the victim and accused to the scene of a crime. It also identifies the gender in missing person identifications, mass disaster cases, and helps in the analysis of samples of sexual assault. The presence of the Y chromosome in a sample determines that it is of a male person. Modern multiplex STR kits have amelogenin locus as a gender-determining mar ...

Abstract:
... Species assignment of any seized material using DNA analysis has been a routine and widely accepted standard procedure in providing scientific advisory for the legal prosecution of wildlife cases. Scientific advancements and rigorous application of genetic tools have led to the development of a variety of molecular markers with their defined efficacy in wildlife forensics. However, in a few unusua ...

Abstract:
... Channel catfish (Ictalurus punctatus) is an important aquaculture species worldwide. Although studies of the sex determination mechanism of channel catfish began during the 1980s, the mechanism and sex-specific genes remain unclear. In this study, based on the results of sex-related quantitative trait locus (QTL) mapping and targeted next-generation sequencing (NGS) technique, 13 male-specific sin ...
Ychromosome, etc ; dissection; hinterland; humans; phylogeny; phylogeography; Show all 6 Subjects
Abstract:
... Uniparental genetic systems are unique sex indicators and complement the study of autosomal diversity by providing landmarks of human migrations that repeatedly shaped the structure of extant populations. Our knowledge of the variation of the male-specific region of the Y chromosome in Native Americans is still rather scarce and scattered, but by merging sequence information from modern and ancien ...
Ychromosome, etc ; databases; forensic sciences; haplotypes; statistics; Show all 5 Subjects
Abstract:
... Y-STR haplotype data from five relevant United States population groups are provided. These data have been shared with the Y-Chromosome Haplotype Reference Database (YHRD) and are relevant for forensic casework statistics, genetic studies and other applicable forensic investigations. ...
Ychromosome, etc ; Scortum barcoo; aquaculture; freshwater fish; genetic improvement; genome; genomics; loci; males; sex determination; sexual dimorphism; transposons; Australia; China; Show all 14 Subjects
Abstract:
... Jade perch (Scortum barcoo) is a new teleost in the developing aquaculture freshwater finfish grow-out sector in Australia and China. However, key information on the breeding sex determination system (SDS) remains poorly understood, hampering sex control programs and genetic improvement. In this study, the jade perch SDS was examined by investigating genome-wide single-nucleotide polymorphisms (SN ...
Ychromosome, etc ; Chinese people; forensic sciences; genome; haplotypes; Show all 5 Subjects
Abstract:
... Y chromosome has an important role in the forensic practice due to its unique paternal inheritance pattern. Y-chromosomal single nucleotide polymorphisms (Y-SNPs) could provide supplementary information while the application of Y-chromosomal STR (Y-STR) haplotypes encounter their limitations. Y-SNPs with recurrent mutation can be seen in different Y-chromosomal haplogroups, which might help discri ...
... Natural hybrid zones provide opportunities for studies of the evolution of reproductive isolation in wild populations. Although recent investigations have found that the formation of neo‐sex chromosomes is associated with reproductive isolation, the mechanisms remain unclear in most cases. Here, we assess the contemporary structure of gene flow in the contact zone between largely allopatric cytoty ...
Ychromosome, etc ; animal genetics; cattle; haplotypes; males; pedigree; France; Show all 7 Subjects
Abstract:
... In this article, we analyzed pedigree information on males from 12 bovine breeds born in France between 2015 and 2019. We report an overall small number of paternal lineages with, for example, a minimal number of ancestors accounting for 95% of the Y‐chromosome pool of their breed ranging from only 2 to 15 individuals. Then, we mined whole‐genome sequence data from 811 sires (2 ≤ n ≤ 510 per breed ...
Ychromosome, etc ; RNA helicases; death; disease progression; lymphoma; males; Show all 6 Subjects
Abstract:
... Gong et al. (2021) demonstrate that MYC-induced proteotoxic stress could be relieved by inactivating RNA helicase DDX3X for tumor initiation, and in male MYC-driven lymphomas, the homologous helicase DDX3Y, encoded on the Y chromosome, is subsequently induced for disease progression. ...
Ychromosome, etc ; Poecilia; alleles; autosomes; females; gene duplication; males; mortality; Show all 8 Subjects
Abstract:
... Differences in allele frequencies at autosomal genes between males and females in a population can result from two scenarios. First, unresolved sexual conflict over survival can produce allelic differentiation between the sexes. However, given the substantial mortality costs required to produce allelic differences between males and females at each generation, it remains unclear how many loci withi ...
Ychromosome, etc ; DNA; DNA fingerprinting; genes; humans; males; monophyly; phylogeography; Show all 8 Subjects
Abstract:
... The Y chromosome is a unique tool for studying the structure of gene pools and the evolutionary history of human populations. Patrilinearity ensures the sequential accumulation of mutations, as a result of which the Y chromosome is a fairly simple marker system for reconstructing evolutionary changes, migration, and other demographic processes in human populations. The analysis of Y-chromosome hap ...
Ychromosome, etc ; DEAD-box RNA helicases; Tan sheep; alleles; animal genetics; gene expression; human genetics; nucleotide sequences; quantitative polymerase chain reaction; testes; testicular development; Show all 11 Subjects
Abstract:
... Variations in the Y‐chromosome are usually correlated with male‐specific traits. However, this condition has been described only sporadically, even in human genetics. The present study was conducted to clone the full‐length gene sequence of ovine DEAD‐box helicase 3, Y‐linked (DDX3Y), and investigate the effect of the expression and variation of DDX3Y on the reproductive traits of Hu sheep. Conseq ...

Abstract:
... In some horse breeds, such as Argentinian Polo Horses, limiting pregnancies to the desired foal sex has both economic and welfare implications. Biopsy of equine embryos to assess embryonic sex by polymerase chain reaction (PCR) on DNA from sampled cells has been reported under research settings and in a limited number of commercial programs. We previously reported the results of embryo biopsy and ...

... To assess the effect of population genetic polymorphism on forensic research, we investigated the genetic polymorphisms of Chinese Kyrgyz group (n = 98) and evaluated forensic application values in Chinese Kyrgyz group and other 26 reference populations at 90 autosomal SNPs, and then combined with 34 SNPs and 37 STRs on Y chromosome to reveal the genetic background of Kyrgyz group in autosomal and ...

Abstract:
... Although the two species of chamois (Rupicapra rupicapra and R. pyrenaica) are currently classified as least-concern by the IUCN (International Union for Conservation of Nature), inconsistencies on the subspecies classification reported in literature make it challenging to assess the conservation status of the single subspecies. Previous studies relying on mitochondrial genes, sometimes in combina ...

Abstract:
... The Atlantic salmon (Salmo salar) is a globally important species for its value in fisheries and aquaculture, and as a research model. In order to characterise aspects of sex differentiation at the morphological and mRNA level in this species, the present study examined developmental changes in gonad morphology and gene expression in males and females between 0 and 79 days post hatch (dph). Morpho ...
... Therian mammals have among the oldest and most conserved sex-determining systems known to date. Any deviation from the standard XX/XY mammalian sex chromosome constitution usually leads to sterility or poor fertility, due to the high differentiation and specialization of the X and Y chromosomes. Nevertheless, a handful of rodents harbor so-called unusual sex-determining systems. While in some spec ...
