This study was conducted to investigate the hair production and fleece characteristics of hairy goats according to the sex and age of animals. The material of the study consisted one total data of 73 hair goats, which were between more than one year-old and one year-old Lori goats from both sexes (26 males and 47 females). The overall fleece weight, fiber length, lock length, washing yield, hai...

Male mate choice might be based on both absolute and relative strategies. Cues of female attractiveness are thus likely to reflect both fitness and reproductive potential, as well as compatibility with particular male phenotypes. In humans, absolute clues of fertility and indices of favorable developmental stability are generally associated with increased women's attractiveness. However, why me...

Although hair form has received much attention in the past, it has rarely been studied systematically, and never using direct curling variables. In the present study, seven groups were scored on eight variables, including four newly-devised curling variables. These data were analyzed using univariate and multivariate techniques to give information about the population relations and mechanisms o...

A hair whorl is a circular patch of that grows in clockwise or counterclockwise pattern around visible central point. Though scalp hair-whorl direction (HWD) one the most phenotypes humans, its formation mechanism and genetic contribution remain unclear. Here, we conducted first genome-wide association study to explore basis HWD. We identified significant at 7p21.3 (P = 2.72 × 10–8) National Su...

With recent advancements in biotechnology, genetic selection of beef cattle has entered the 21st century. Cattle producers now have the ability to assess the genetic makeup of an individual animal through the use of genetic markers. Using a tissue sample (hair, blood, muscle, etc.), cattle can be tested to see if they carry certain genes and whether the allelic combinations within the gene will...

cartilage hair hypoplasia (chh), is a rare cause of metaphyseal chondrodysplasia and short stature. other features included hair abnormality, immunodeficiency, anemia, gastrointestinal disorders (hirschsprung disease, celiac, …) and increased risk of cancer. the disease is an autosomal recessive disorder and previously has not been reported in iran. we report a 9-year-old boy diagnosed as carti...

In the current paper we investigate whether gender aVects the encoding of leadership behavior. In three studies we found evidence that perceivers had diYculty encoding leadership behaviors into their underlying prototypical leadership traits when the behavior implied an agentic trait and the behavior was enacted by a female. Using a lexical decision making task, in Study 1 we demonstrated that ...

Given finite resources, intense investment in one life history trait is expected to reduce investment in others. Although telomere length appears to be strongly tied to age in many taxa, telomere maintenance requires energy. We therefore hypothesize that telomere maintenance may trade off against other life history characters. We used natural variation in laboratory populations of Atlantic silv...

kawasaki disease is a multi system disorder with varying clinical expressions. this disease is an acute systemic vasculitis of unknown etiology that has recently recognized as a leading cause of acquired heart disease in children of many developed countries. we describe an unusual instance of hair loss in a patient with kawasaki disease. a 26 months old boy developed prolonged high fever, bilat...

OBJECTIVE The existing methods for identifying multiple rare variants underlying complex diseases in family samples are underpowered. Therefore, we aim to develop a new set-based method for an association study of dichotomous traits in family samples. METHODS We introduce a framework for testing the association of genetic variants with diseases in family samples based on a generalized linear ...
