The estimation of quantitative genetic parameters in wild populations is generally limited by the accuracy and completeness of the available pedigree information. Using relatedness at genomewide markers can potentially remove this limitation and lead to less biased and more precise estimates. We estimated heritability, maternal genetic effects and genetic correlations for body size traits in an...

Heritability is a central element in quantitative genetics. New molecular markers to assess genetic variance and heritability are continually under development. The availability of molecular single nucleotide polymorphism (SNP) markers can be applied for estimation of variance components and heritability on population, where relationship information is unknown. In this study, we evaluated the c...

Endocrine disorders are substantial contributors to neonatal morbidity and mortality and, of these, congenital hypothyroidism (CH) is the most common (Kumar et al. 2009). CH is a common and preventable cause of mental retardation with an incidence of approximately 1 in 2,350 live births (Hinton et al. 2010). In Iowa, the Iowa Neonatal Metabolic Screening program (INMSP) uses thyroid stimulating...

Heritability of 2-yr-old heifer calving difficulty score was estimated in nine purebred and three composite populations with a total of 5,986 calving difficulty scores from 520 sires and 388 maternal grandsires. Estimates were 0.43 for direct (calf) genetic effects and 0.23 for maternal (heifer) genetic effects. The correlation between direct and maternal effects was -0.26. Direct effects were ...

genomic selection is a method to predict the breeding values of individuals using a large number of single nucleotide polymorphism markers. the cost of the high-density marker panel genotyping is very high, which prevents the widely application of genomic selection. the present simulation study was carried out to evaluate the use of low to medium marker density panels to predict direct genomic ...

The experiment was carried out to determine the genetic variability parameters and character associations for eleven quantitative traits in Indian bean genotypes. It revealed a significant amount of present among these Seed yield per plant had high Genotypic coefficient variation (GCV) Phenotypic (PCV) values, showing potential improvement by selection. Racemes plant, pods raceme, pods pod...

The present experiment was conducted with 16 germplasms and two varieties of snake gourd. yield contributing traits such as node order first male flower, female days to flowering, internodal length, harvest, single fruit weight, girth, number fruits per plant, were studied assess the genetic variability, heritability advance besides correlation path coefficient analysis. study GCV PCV in gourd ...

Parental effort has a direct impact on individual fitness. Theoretical models exploring how parental effort evolves to cope with offspring demand and sexual conflicts may differ in the assumptions they make in respect to the genetic heritability of parental behaviours. Only a few attempts, however, have been made to estimate the heritability of parental behaviours and their possible co-evolutio...

We consider the problem of coding labelled trees by means of strings of vertex labels and we present a general scheme to define bijective codes based on the transformation of a tree into a functional digraph. Looking at the fields in which codes for labelled trees are utilized, we see that the properties of locality and heritability are required and that codes like the well known Prüfer code do...

the genetic parameters and (co) variance components of body weight at birth (bw), weaning (ww) and six months of age (bw6) and average daily gain (adg) pre and post-weaning of afshari sheep were estimated using restricted maximum likelihood (reml) methodology and animal model implemented in dfreml software. the likelihood ratio test (lrt) was used to compare the models. year of birth, age of mo...
