The present study estimated the heritability of natural antibody (NAb) levels binding rabbit red blood cells at the day of immunization with SRBC (NAb0) and 5 d postimmunization (NAb5) in 2 chicken lines divergently selected for specific antibody levels (SpAb) against SRBC and a randombred control line. In addition, genetic correlations between the levels of NAb binding rabbit red blood cells a...
The popular Genome-wide Complex Trait Analysis (GCTA) software uses the random-effects models for estimating the narrow-sense heritability based on GWAS data of unrelated individuals without knowing and identifying the causal loci. Many methods have since extended this approach to various situations. However, since the proportion of causal loci among the variants is typically very small and GCT...
BACKGROUND Brain abnormalities of subcortical and limbic nuclei are common in patients with schizophrenia, and variation in these structures is considered a putative endophenotype for the disorder. Multiplex-multigenerational families with schizophrenia provide an opportunity to investigate the impact of shared genetic ancestry, but these families have not been previously examined to study stru...
Abstract In the field of evolutionary robotics, choosing correct genetic representation is a complicated and delicate matter, especially when robots evolve behaviour morphology at same time. One principal problem lack methods or tools to investigate compare representations. this paper we introduce evaluate such tool based on biological notion heritability. Heritability captures proportion pheno...
fennel (foeniculum vulgare mill.) benefits from a lot of useful medicinal properties. iran is known as one of the main producers of fennel. in spite of high medicinal values, fennel’s cultivation is not economically feasible, mainly due to its low yield. it grows wild in different areas in iran from where diverse ecotypes have evolved. genetic variance and heritability estimates of traits in a ...
estimation of genetic parameters for pre weaning growth traits and lamb survival in iran black sheep
the aims of this research were to estimate of genetic parameters for pre-weaning traits and lamb survival in iran-black sheep. for this purpose 6344 records for birth weight (bw) and lamb survival (ls) and 5264 records for weaning weight (ww), average daily gain (adg) and kleiber ratio (kr) were available, which collected by abbasabad animal breeding and rearing station, over the period from 19...
Yardlong bean pod used as vegetable in many countries. has agronomic character variability such length, immature and seed colour. The colour are green, whitish green red. Fagiola variety red pod, while "Aura Hijau" pod. aim of research was to evaluate characters F3 progenies. Artificial crossing made between "Fagiola" female parent male produce F1. F1 were self-pollinated F2. Then F2 obtain Pro...
The aim of this study was to compare different methods of Bayesian (parameteric) approaches for predicting genomic breeding values of traits with different genetic architecture in different distribution of gene effects, number of quantitative traits loci, heritability and the number of reference population using simulated data. A genome contained 3 chromosomes, with the length of 100 cM and 10...
