DairyTalk 297: Breeding as Applied Probability: How Mendelian Laws Still Guide Modern Genomics - by Helmut Demmelhuber

This episode draws on a technical article explaining how
Mendelian inheritance continues to shape modern Holstein
breeding, using coat color as a practical example. It outlines
how the principles of dominance and recessiveness determine
whether calves are born black or red, with red expression
occurring only when two recessive alleles are inherited. The
analysis demonstrates that color outcomes can be predicted with
statistical accuracy rather than left to chance. Even in the age
of advanced genomic tools, these classical genetic rules remain
the structural basis for understanding trait transmission. The
podcast places this genetic logic into context, highlighting
breeding as a discipline grounded in applied probability.
