Bayesian Variable Selection Of Pathway Gene Sets Applied To Gene Expression Microarray Data
For some diseases or other phenotypes it is not only interesting to identify which genes are
involved but also to find the involved processes or pathways. This is often done using sets of
genes such as genetic ...
Genomic Estimation Of Heritability Under Different Gene Action Scenarios
Different versions of genomic models are proposed to predict breeding values for animals using
dense markers. However, so far little attention has been payed to estimating the genomic
explained variance from ...
MCMC strategies for a Bayesian analysis of reaction norm models with unknown covariates
The performance of three versions of the Gibbs sampling algorithm, and of two versions of the Langevin-Hastings algorithm were studied in a specific application involving an analysis of a reaction norm model. Two datasets ...
Efficiency of alternative MCMC strategies illustrated using the reaction norm model
The Markov chain Monte Carlo (MCMC) strategy provides remarkable flexibility for fitting complex hierarchical models. However, when parameters are highly correlated in their posterior distributions and their number is ...
Genetic Analysis of Somatic Cell Score in Danish Holsteins Using a Liability-Normal Mixture Model
Mixture models are appealing for identifying hidden structures affecting somatic cell score (SCS) data, such as unrecorded cases of subclinical mastitis. Thus, liability-normal mixture (LNM) models were used for genetic ...
A two step Bayesian approach for genomic prediction of breeding values
Background
In genomic models that assign an individual variance to each marker, the contribution of one marker to the posterior distribution of the marker variance is only one degree of freedom (df), which introduces ...
Molecular investigation of Y chromosome microdeletions in AZF regions of the non-obstructive azoospermic and oligospermic patients referred to Montaseriyeh infertility center in Mashhad
Background and Aim: The Y-chromosome azoospermic factor (AZF) regions consist of genes whose
specific roles and functions in spermatogenesis and fertility have not been completely clarified. Hence,
recognition ...
Molecular identification of infertile bulls by using newly developed DDX3Y based on human STS markers
To determine the role of DDX3Y gene in spermatogenesis and infertility in bulls, blood samples were collected from five infertile bulls (azoospermic; no sperm in the semen) at the Animal Breeding Center in Karaj, Iran. The ...
اثر سن اولین زایش بر فاصله گوساله زایی و طول دوره خشکی گاوهای شیری در اقلیم نیمه خشک ایران
این تحقیق به منظور بررسی تأثیر سن اولین زایش بر صفات فاصله گوساله زایی و طول دوره خشکی گاوهای هلشتاین اقلیم نیمه خشک بیابانی ایران انجام شد. داده ها متعلق به دوره اول شیردهی 57870 رأس گاو شیری هلشتاین، که طی سال های 1374 ...
اثر سن اولین زایش بر صفات تولید شیر گاوهای شیری در اقلیم نیمه خشک ایران
این تحقیق به منظور بررسی اثر سن اولین زایش بر صفات تولید شیر، چربی و پروتئین 305 روز گاوهای شیری اقلیم نیمه خشک بیابانی ایران انجام شد. دادهها متعلق به دوره اول شیردهی 58872 رأس گاو شیری بودند که طی سالهای 1375 تا 1390 ...
