I suggest reading the link I posted plus other material on genomic selection. The type of genomic selection used in the dairy industry is very different from simple 23andMe type genetic screening.
I read the abstract.
The link says they do 50,000 SNP’s with their chip in the dairy industry. 23andMe does hundred thousands of SNPs according to their website.
They do some statistics with that data because to see which SNPs are important but otherwise I don’t see what they do much different.
High SNP numbers are misleading and have little predictive value. But that’s not the important bit; the important bit is how this information is actually used.
