Managing Genetic Conditions

6 April 2017

A genetic condition is caused by an abnormality in an individual’s DNA. These abnormalities can range from a single gene mutation to the addition or loss of an entire chromosome. Genetic conditions have been identified in most species, including humans, and more than 400 genetic conditions have been identified in beef cattle. Approximately one quarter of these conditions are caused by a single gene mutation, making them easy to manage through DNA testing. Historically, before DNA tests were available, genetic conditions were managed by extensive progeny testing or by eradicating all known relatives of the affected animal.
