Dominance, epistasis, heritabilities and expected genetic gains
Although epistasis is common in gene systems that determine quantitative traits, it is usually not possible to estimate the epistatic components of genotypic variance because experiments in breeding programs include only one type of progeny. As the study of this phenomenon is complex, there is a lack of theoretical knowledge on the contribution of the epistatic variances when predicting gains f...
متن کاملAutomatic Detection of Dominance and Expected Interest
Social Signal Processing is an emergent area of research that focuses on the analysis of social constructs. Dominance and interest are two of these social constructs. Dominance refers to the level of influence a person has in a conversation. Interest, when referred in terms of group interactions, can be defined as the degree of engagement that the members of a group collectively display during ...
متن کاملExpected Gains from Parallelizing Constraint Solving for
A number of recent studies have examined how the difficulty of various NP-hard problems varies with simple parameters describing their structure. In particular, they have identified parameter values that distinguish regions with many hard problem instances from relatively easier ones. In this paper we continue this work by examining independent parallel search. SpecificalIy, we evaluate the spe...
متن کاملDominance, epistasis and the genetics of postzygotic isolation.
The sterility and inviability of species hybrids can be explained by between-locus "Dobzhansky-Muller" incompatibilities: alleles that are fit on their "normal" genetic backgrounds sometimes lower fitness when brought together in hybrids. We present a model of two-locus incompatibilities that distinguishes among three types of hybrid interactions: those between heterozygous loci (H(0)), those b...
متن کاملLaboratory estimates of heritabilities and genetic correlations in nature.
A lower bound on heritability in a natural environment can be determined from the regression of offspring raised in the laboratory on parents raised in nature. An estimate of additive genetic variance in the laboratory is also required. The estimated lower bounds on heritabilities can sometimes be used to demonstrate a significant genetic correlation between two traits in nature, if their genet...
