Frontiers in Marine Science, 2021 Heterosis is a widely distributed phenomenon in mollusks. It is vital in aquaculture by bringing beneficial traits into hybrids. People have utilized the heterosis theory in aquaculture for years. However, the molecular basis of heterosis remains elusive.

Expression of PEG11 and PEG11AS transcripts in normal and callipyge sheep [PDF]
, 2004 BACKGROUND: The callipyge mutation is located within an imprinted gene cluster on ovine chromosome 18. The callipyge trait exhibits polar overdominant inheritance due to the fact that only heterozygotes inheriting a mutant paternal allele (paternal ...

Cryptic MHC Polymorphism Revealed but Not Explained by Selection on the Class IIB Peptide-Binding Region [PDF]
, 2012 The immune genes of the major histocompatibility complex (MHC) are characterized by extraordinarily high levels of nucleotide and haplotype diversity. This variation is maintained by pathogen-mediated balancing selection that is operating on the peptide ...

Genome-Wide Linkage Analysis to Identify Chromosomal Regions Affecting Phenotypic Traits in the Chicken. I. Growth and Average Daily Gain [PDF]
, 2006 Two informative chicken F2 populations based on crosses between a broiler breeder male line and dams from genetically distinct, highly inbred (\u3e99%) chicken lines, the Leghorn G-B2 and Fayoumi M15.2, have been used for genome-wide linkage and QTL ...

Overdominant Alleles in a Population of Variable Size [PDF]
Genetics, 1999 Abstract An approximate method is developed to predict the number of strongly overdominant alleles in a population of which the size varies with time. The approximation relies on the strong-selection weak-mutation (SSWM) method introduced by J. H.

Inference of Selection Based on Temporal Genetic Differentiation in the Study of Highly Polymorphic Multigene Families [PDF]
, 2012 The co-evolutionary arms race between host immune genes and parasite virulence genes is known as Red Queen dynamics. Temporal fluctuations in allele frequencies, or the ‘turnover’ of alleles at immune genes, are concordant with predictions of the Red ...

Quantitative Insights into the Genetic Mechanisms of Crop Heterosis. [PDF]
Adv Genet (Hoboken)Inheritance patterns of genomics‐downstream molecules, including transcripts, proteins, and metabolites, are analyzed in hybrid crops. The additive effect, which describes mid‐parent level, is a predominant inheritance pattern in crop heterosis and can be used to improve breeding efficiency of high‐yield hybrid varieties.

Overdominant effect of a CHRNA4 polymorphism on cingulo-opercular network activity and cognitive control [PDF]
, 2017 The nicotinic system plays an important role in cognitive control, and is implicated in several neuropsychiatric conditions. Yet, the contributions of genetic variability in this system to individuals' cognitive control abilities are poorly understood ...
