The presence of heterosis has been observed in many species at both phenotypic and gene levels. Strangely, the genetic basis of heterosis was and still is largely unknown. In this study, we extended and simplified some formulas that we reported previously. The foundation of our model was based on partitioning the F 1 phenotypic variance of the cross between two pure lines into additive, dominance and epistasis components, which lead to the estimation of effective factors, crossheritability in the broad and narrow sense and heterotic power. In the model, we assume that all polygenes controlling a quantitative trait have an equal genetic effect and are independent of each other. By extension of the heritability to a cross population, new features appear. Lastly, an example of employing the proposed method in analyzing the crossing data from Drosophila melanogaster is given to illustrate its application.
For a couple of days I've been thinking about the canon of animal breeding, the important works that every student should read. I'm not up to the task right now of assembling a list of key scientific papers, and I suspect that there's already a good list somewhere that I can use as a starting point, so I'm going to go for low-hanging fruit instead. These are five books that I think that every graduate student in animal breeding should work through, reading the text and working the exercises as they go. Note that these are just my opinions, and there are some other very good books out there. Bourdon's introduction to animal breeding text is dated, but has some very nice things in it. Ignacy Misztal's course notes on Computational techniques in animal breeding link to PDF are a great resource for anyone interested in the software implementation of genetic evaluations. I'm sure there are other great sources that I'm not thinking of at the moment.
