Andres Legarra


I am Research Director at INRA Toulouse in the GenPhySE unit, at the Animal Genetics department. My work is related to quantitative genetics and genetic evaluation of livestock. E-mail me at andres dot legarra at inrae dot fr .

I did my PhD in Neiker with Eva Ugarte and I did a postdoc at the Animal and Dairy Science Department at the University of Georgia, with Ignacy Misztal and Keith Bertrand.

This is my new, non-fancy web page created with markdown and MacDown.

I have developed my own programs

and helped in others’ people programs:


Course on Genomic Selection

This is a course that is taught every two years at UGA, with materials of the 2018 edition . I often teach a part of it. Some materials that we have constructed for this course include notes Bases for Genomic Prediction in pdf , in epub , and in single-file html (but without the Appendix) formats.

Other material


In our POCTEFA grant that what called Genomia, we wrote a document with the state of the art of dairy sheep selection across the Pyrenees. You can find it here.


Our paper in metafounders’ theory contained source code that is lost from the new Genetics site. You cand found this source code here.

I have written a tutorial, here on the use of metafounders to analyse crossbred data with the blupf90 wiki suite using SSGBLUP. The tutorial is conceived for 3-way crosses but the ideas inside can be used (easily) for 2- or 4-way crosses or (a bit more difficult) for complex crosses like in sheep. This work has been financed by Smarter.

Method LR

Similarly, another tutorial here explains the use of method LR to analyze bias and accuracies of evaluation (including genomic prediction). This work has been financed by Smarter.

Quick notes for myself on Julia

Really nothing very sophisticated.
