Imputation accuracy and carrier frequency of deleterious recessive defects in Australian dairy cattle.

Widespread genotyping has enabled the identifica- tion of putative recessive mutations that affect fertility through early embryonic fetal loss, or compromise neo- nate or calf viability. The use of artificial insemination in the global dairy population can rapidly spread these harmful mutations, and testing for multiple mutations can become relatively expensive if not all tests are avail- able on the same SNP panel. However, it is possible to provide heifer and cow predicted carrier status to...
