DOI: 10.1002/ajb2.16083
Abstract: PREMISE The evolutionary response of a trait to environmental change depends upon the level of additive genetic variance. It has been long argued that sustained selection will tend to deplete additive genetic variance as favoured… read more here.

DOI: 10.1007/s13131-017-1034-y
Abstract: Bayesian and restricted maximum likelihood (REML) approaches were used to estimate the genetic parameters in a cultured turbot Scophthalmus maximus stock. The data set consisted of harvest body weight from 2 462 progenies (17 months… read more here.

DOI: 10.1093/genetics/iyaa048
Abstract: Abstract Cultivated bread wheat (Triticum aestivum L.) is an allohexaploid species resulting from the natural hybridization and chromosome doubling of allotetraploid durum wheat (T. turgidum) and a diploid goatgrass Aegilops tauschii Coss (Ae. tauschii). Synthetic… read more here.

Genomic dissection of repeatability considering additive and non-additive genetic effects for semen production traits in beef and dairy bulls.

DOI: 10.1093/jas/skac241
Abstract: The low heritability and moderate repeatability of semen production traits in beef and dairy bulls suggest that non-additive genetic effects, such as dominance and epistatic effects, play an important role in semen production and should… read more here.

DOI: 10.1111/mec.15027
Abstract: Estimation of effective population size (Ne) from genetic marker data is a major focus for biodiversity conservation because it is essential to know at what rates inbreeding is increasing and additive genetic variation is lost.… read more here.

DOI: 10.3168/jds.2022-22578
Abstract: Structural equation models allow causal effects between 2 or more variables to be considered and can postulate unidirectional (recursive models; RM) or bidirectional (simultaneous models) causality between variables. This review evaluated the properties of RM… read more here.

DOI: 10.3389/fpls.2022.1027558
Abstract: Using data from genome-wide molecular markers, genomic selection procedures have proved useful for estimating breeding values and phenotypic prediction. The link between an individual genotype and phenotype has been modelled using a number of parametric… read more here.
