The objective of the study was to estimate the genetic relationships between detailed reproductive traits derived from ultrasound examination of the reproductive tract and a range of performance traits in Holstein-Friesian dairy cows. The performance traits investigated included calving performance, milk production, somatic cell score (i.e., logarithm transformation of somatic cell count), carc...

In humans, the majority of studies demonstrate an age-associated reduction in the number of capillaries surrounding skeletal muscle fibers; however, recent reports in rats suggest that muscle capillarization is well maintained with advanced age. In sedentary and trained men, aging lowers the number of capillaries surrounding type II, but not type I, skeletal muscle fibers. The fiber type-specif...

The causal correlations between human genetic variants and linguistic (typological) features could represent the mechanism required for gradual, accretionary models of language evolution. The causal link is mediated by the process of cultural transmission of language across generations in a population of genetically biased individuals. The particular case of Tone, ASPM and Microcephalin is disc...

The study aimed to estimate the level of yield gaps maize in major producing areas, point out causes farmers’ fields, and identify opportunities existing through management practices production Central Java. This is strategy for closing achieve food self-sufficiency agricultural land. Methods estimates should cover data sources on physical conditions (weather soil), practices, smallholder shape...

This study investigated the prospective links of negative life events and parent-child closeness with depressive symptoms among siblings using a multilevel modeling approach with a genetically informative design. The sample consisted of 756 adolescents (378 sibling pairs) who participated in two waves of the Nonshared Environment in Adolescent Development Project. Sibling pairs with varying deg...

in this study test-day records of milk (kg), fat (g), and protein (g) yields, somatic cell score (scs, cells/ml) collected by animal breeding center of iran during 2007 and 2009 were used to estimate genetic parameters using random regression model. models with different order of legendre polynomials were compared using bayesian information criterion (bic).for milk, fat yield and scs genetic an...

This study investigated the prospective links between sibling aggression and the development of externalizing problems using a multilevel modeling approach with a genetically sensitive design. The sample consisted of 780 adolescents (390 sibling pairs) who participated in 2 waves of the Nonshared Environment in Adolescent Development project. Sibling pairs with varying degree of genetic related...

The longitudinal rank-order stability of cognitive ability increases dramatically over the life span. Theoretical perspectives differ in their emphasis on genetic mechanisms in explaining the longitudinal stability of cognition and how stability changes with development. However, the patterns of stability of genetic and environmental influences on cognition over the life span remain poorly unde...

The YesWorkflow (YW) toolkit aims to provide users of scripting languages such as Python, Perl, and R with many of the benefits of scientific workflow automation. YW requires neither the use of a workflow engine nor the overhead of adapting or instrumenting code to run in such a system. Instead, YW enables scientists to annotate their scripts with special comments that reveal the main computati...

We determined reaction norms for developmental time and weight at eclosion for 2 isozygous and 11 genetically mixed strains of Drosophila mercatorum in four culture media differing in yeast concentration. With decreasing yeast concentration, development was delayed, the weight of emerging flies decreased, and the phenotypic variance of both variables increased. Differences among stocks and sign...
