Quantitative genetics model as the unifying model for defining genomic relationship and inbreeding coefficient. [PDF]

open access: yesPLoS ONE, 2014
The traditional quantitative genetics model was used as the unifying approach to derive six existing and new definitions of genomic additive and dominance relationships.

Genetics of grain yield and its component traits in maize (Zea mays L.)

open access: yesElectronic Journal of Plant Breeding, 2022
The six essential generations (2 parents, F1, F2 and backcrosses) of the cross NAI-137 × 97B developed from two parents distinguishable for grain yield were evaluated to construe the genetics of grain yield and its component quantitative traits during ...

Natural selection. III. Selection versus transmission and the levels of selection [PDF]

open access: yes, 2011
George Williams defined an evolutionary unit as hereditary information for which the selection bias between competing units dominates the informational decay caused by imperfect transmission.

Genetic architecture studies of yield and its components in castor

open access: yesElectronic Journal of Plant Breeding, 2018
Generation mean analysis implies to study genetics of seed yield and its components in castor (Ricinus communis L.) through generation mean analysis. The additive-dominance model was found adequate for days to maturity of primary spikes in cross I (AKC-

Resistance to Ralstonia Solanacearum of sexual hybrids between Solanum commersonii and S. tuberosum [PDF]

open access: yes, 2009
This research was carried out to study the levels of bacterial wilt resistance and genetic diversity of (near) pentaploid sexual hybrids between S. commersonii (2n = 2x = 24, 1EBN) and cultivated S. tuberosum.

Genetic Effects and Heterosis of Yield and Yield Component Traits Based on Gossypium Barbadense Chromosome Segment Substitution Lines in Two Gossypium Hirsutum Backgrounds. [PDF]

open access: yesPLoS ONE, 2016
We hybridized 10 chromosome segment substitution lines (CSSLs) each from two CSSL populations and produced 50 F1 hybrids according to North Carolina Design II.

Assessment of the dynamics of microparasite infections in genetically homogeneous and heterogeneous populations using a stochastic epidemic model [PDF]

open access: yes, 2008
The aim of this paper was to explore the effect of genetic heterogeneity in host resistance to infection on the population-level risks and outcomes of epidemics.

Benefits of Dominance over Additive Models for the Estimation of Average Effects in the Presence of Dominance

open access: yesG3: Genes, Genomes, Genetics, 2017
In quantitative genetics, the average effect at a single locus can be estimated by an additive (A) model, or an additive plus dominance (AD) model. In the presence of dominance, the AD-model is expected to be more accurate, because the A-model falsely ...

A QTL for osteoporosis detected in an F2 population derived from White Leghorn chicken lines divergently selected for bone index [PDF]

open access: yes, 2007
Osteoporosis, resulting from progressive loss of structural bone during the period of egg-laying in hens, is associated with an increased susceptibility to bone breakage.

Dominance vs epistasis: the biophysical origins and plasticity of genetic interactions within and between alleles

open access: yesNature Communications, 2023
An important challenge in genetics, evolution and biotechnology is to understand and predict how mutations combine to alter phenotypes, including molecular activities, fitness and disease.
