Abstract Eurasians have ~2% Neanderthal ancestry, but we lack a comprehensive understanding of the genome-wide influence introgression on modern human diseases and traits. Here, quantify contribution introgressed alleles to heritability more than 400 diverse We show that genomic regions in which detectable ancestry remains are depleted for all traits considered, except those related skin hair. ...

This study was conducted to investigate the hair production and fleece characteristics of hair goats in Fars province. The material of the study included a total data of 84 hair goats, which were between kids and adult in male and female goats, respectively. The overall average for fleece weight, fiber length, staple lengths, washing yield, hair fiber diameter, of fiber diameter, breaking force...

Unimodal biometric system uses only single trait of biometric for recognition and do not provide secured application. Multimodal biometric combines different physical and behavioral traits such as face and finger other traits such as skin color, age, height, hair color, eye color, provide reliable authentication because the nature of these t property in soft biometrics, it can be used with othe...

Assessing the genetic contribution of Neanderthals to non-disease phenotypes in modern humans has been difficult because of the absence of large cohorts for which common phenotype information is available. Using baseline phenotypes collected for 112,000 individuals by the UK Biobank, we can now elaborate on previous findings that identified associations between signatures of positive selection ...

Pigmentation of the skin, hair, and eyes varies both within and between human populations. Identifying the genes and alleles underlying this variation has been the goal of many candidate gene and several genome-wide association studies (GWAS). Most GWAS for pigmentary traits to date have been based on subjective phenotypes using categorical scales. But skin, hair, and eye pigmentation vary cont...

Ultraviolet-B (UV-B) radiation is a key but under-researched environmental factor that initiates diverse responses in plants, potentially affecting their distribution. To date, only a few macroecological studies have examined adaptations of plant species to different levels of UV-B. Here, we combined herbarium specimens of Hieracium pilosella L. and Echium vulgare L. with a novel UV-B dataset t...

Follistatin (FST) is involved in hair follicle morphogenesis. However, its effects on hair traits are not clear. This study was designed to investigate the effects of FST gene single nucleotide polymorphisms (SNP) on wool quality traits in Chinese Merino sheep (Junken Type). We performed gene expression analysis, SNP detection, and association analysis of FST gene with sheep wool quality traits...

Research has shown that human partners are more similar than expected by chance on a variety of traits. Studies examining hair and eye colour show some evidence of positive assortment. Positive assortment may reflect attraction to self-similar characteristics but is also consistent with attraction to parental traits. Here, we examine self-reported partner hair and eye colour and the influence t...

Although testosterone is associated with aggression in the popular imagination, previous research on the links between testosterone and human aggression has been inconsistent. This inconsistency might be because testosterone's effects on aggression depend on other moderators. In a large adolescent sample ( N = 984, of whom 460 provided hair samples), we examined associations between aggression ...

Wheat is an important cereal crop worldwide that often suffers from moisture deficits at the reproductive stage. Polyethylene glycol (PEG)-treated hydroponic conditions create negative osmotic potential which is compared with moisture deficit stress. An experiment was conducted in a growth chamber to study the effects of PEG on root hair morphology and associated traits of wheat varieties. Plan...
