I cut below text from http://www.gsejournal.org/content/pdf/1297-9686-42-37.pdf
It just sent to my e-mail few minutes ago.
It was the most recent progress in genetics research.
==============================
Genomic selection has become a routine in dairy cattle breeding programs worldwide. The
current cost of whole-genome selection based on dense SNP genotypes has limited the
application to the selection of elite males and females that are likely to become parents of
the next generation. Results of our study indicate that accurate genomic evaluation of the
broader bull and cow population can be achieved with genotyping assays containing ~
3,000 to 5,000 SNP. A chip containing 3,000 evenly spaced markers can provide
approximately 90% of the accuracy achieved with a high-density SNP assay for genomic
selection of bulls and cows combined across traits. Possible applications include the
selection of replacement heifers and the pre-screening of young bulls and potential bull
dams. Assays with evenly spaced markers are preferable as they can be used across traits
and possibly across populations. It also allows for a high volume generic chip to be
produced, which will lower assay cost per individual and will limit heterogeneity of
genomic information compared to using multiple assays for different traits. Evenly spaced low-density assays might also permit the reconstruction of the genotype information of
high-density assays through imputation, which is important in situations where, for
example, high-density genotyping is limited to nucleus breeding herds. Increasing the
proportion of animals genotyped will further increase the accuracy of genomic selection as
the training data grows over time, particularly through genotyping of cows.
=================
The point I want to make is above conclusion is a strong evidence why TH EDU was won.
Because it was exactly follow what farang lie to us and made us to follow them.
All research in this area now did only one thing with one track mind. They lack off variability to think of other things that explain the same nature.
Ofcause, when I say so I do have other different theories to explain the same phenomena.
