Effect of soil applied zinc sulphate on wheat (Triticum aestivum L.) grown on a calcareous soil in Pakistan [PDF]
, 2008 A field experiment was conducted to investigate the effect of soil application of zinc fertilizer on yield and yield components of wheat (Triticum aestivum L. cv. Inqlab 91) grown on calcareous soil in Pakistan.

Conditional Overdominance at an Alcohol Dehydrogenase Locus in Yeast [PDF]
Genetics, 1987 ABSTRACT Documented examples of heterosis attributable to overdominance at specific protein-encoding gene loci have rarely been reported, the association of sickle cell hemoglobin with malarial resistance being the best documented example of this phenomenon.

Structural Variations Contribute to Subspeciation and Yield Heterosis in Rice
Plant Biotechnology Journal, EarlyView.ABSTRACT Yield heterosis has been extensively exploited in hybrid breeding, with intersubspecific hybrids often exhibiting the most pronounced effects. However, developing elite hybrids remains a laborious and time‐consuming process. The genetic basis of heterosis has been debated for over a century, hindered largely by the lack of high‐quality genomes.

The effect of initial linkage disequilibrium and natural selection in pooled populations : experiments with Tribolium and simulation [PDF]
, 1972 In chapter 2 a number of the mechanisms are discussed through which genetic polymorphisms can be maintained in natural populations: overdominance, frequency dependent selection and neutral alleles with associative overdominance.

Contemporary hybridization among Arabis floodplain species creates opportunities for adaptation
New Phytologist, Volume 249, Issue 3, Page 1542-1557, February 2026.Summary Hybridization between closely related species is increasingly recognized as a major source of biodiversity. Yet, whether it can create advantageous trait combinations while purging harmful alleles remains unknown. To address this question, we studied Arabis nemorensis and Arabis sagittata, two endangered species that currently hybridize in a ...

Genetic analysis of the hybrid rice population ‘Mavr × Kontakt’
Зерновое хозяйство России, 2021 Rice can form not only white-color kernels, but also of red, brown and black colors. In black-color rice kernels, the pericarp contains anthocyanin, which has antioxidant activity and therefore has a positive effect on human health.

Population Ecology, Volume 68, Issue 1, January 2026.Population size and dynamics fundamentally shape speciation by influencing genetic drift, founder events, and adaptive potential. Small populations may speciate rapidly due to stronger drift, whereas large populations harbor more genetic diversity, which can alter divergence trajectories. We highlight theoretical models that incorporate population size

Gene action associated with heterosis expression in scarlet eggplant (Solanum gilo Raddi.)
Revista de la Facultad de Ciencias Agrarias, 2015 The objectives of this work were to assess heterosis and its components in F1 hybrids of a diallel cross among lines of scarlet eggplants (Solanum gilo Raddi, syn. S. aeth opicum L.), and to study the modes of gene action associated with its expression.

Fecundity of paternal and maternal non-parental female relatives of homosexual and heterosexual men. [PDF]
PLoS ONE, 2012 A variety of social, developmental, biological and genetic factors influence sexual orientation in males. Thus, several hypotheses have attempted to explain the sustenance of genetic factors that influence male homosexuality, despite decreased fecundity ...

Crop Science, Volume 66, Issue 1, January/February 2026.Abstract Six sets of 48 maize (Zea mays L.) inbred lines, and their 96 single crosses generated using the North Carolina Mating Design II system, were evaluated for resistance to gray leaf spot (GLS). The aim of the study was to assess the implications of combining ability, heterotic effects, and potence ratio in breeding for GLS resistance in maize ...
