Document Summary

What if we have multiple markers: predicting inheritance of qtl. ~ w. marker panels have numerous markers on 1 panel. ~ don"t normally put markers on the sex chromosomes. ~ can start to combine markers and tract if recombination event has occurred. ~ each chip costs ~ for each animal you genotype 30827$ **** proportions are missing the divider on slide 25. Ans: a difference in the avg phenotype btw marker genotypes, linkage btw the marker locus and the qtl, Large number of genotyped individuals, a well supported research budget. Q: which is the most important for successful qtl detection. A difference in the average phenotype btw marker genotypes. Which implies linkage btw the marker locus and qtl. ~ traits will low heritability include health and reproduction. ~ selection response is a function of heritability. ~ heritage breeds of pigs, tamworth breed reported to have very different bacon. When you have the bacon, carcass isn"t capable of making more bacon.
