Summary

Resistance to mastitis is a classic quantitative/multifactorial/complex trait. Typically it is quantified in terms of a somatic cell count (SCC) from a sample of milk. The trait is sufficiently heritable to have been included in many herd improvement programs around the world. In recent years, genome-wide association studies (GWAS) with SNP chips have begun to identify QTL for this trait. As yet there are no agreed quantitative trait nucleotides (QTN). Liu et al. (2014): "report the production of cloned cows carrying human lysozyme gene knock-in β-casein locus using ZFNs." This study involves genetically modified organisms (GMO).
