Hello, this is Daniel Gianola from the University of Wisconsin-Madison and Technical University of Munich, Germany. And I will start discussing the second part of the presentation concentrating on the impact of "Genomics in Animal Breeding".

So now we're about to enter the genomic era, but until we actually had a massive number of molecular markers, we were using linear models, using phenotypes and pairing research inputs. But in the mean time, the Edinburgh school kept working on the basic foundations of quantitative genetics. And I would like to mention Alan Robertson and William Hill from the University of Edinburgh that did considerable work on the quantitative genetics of small populations. What would be the fate of favorable alleles in the selection process? And what would be the probability of fixation? That's the first formula. And then we have a series of curves that show the chance of fixation of recessive alleles as a function of population size and selection intensity. So we were working with this sort of black box, blind statistical models, but at the same time there were persons such as Hill and Robertson working on the underlying theory that we would need at some point. And the time came when genomics began to be applied in animal and plant breeding.
