Contractural Arachnodactyly (CA) is a simple recessive trait in beef cattle. CA is better known as “fawn calf” as affected calves have hunched hind quarters similar to young deer. This condition affects Angus and Angus-derived cattle. CA is not a lethal mutation but it does affect the productivity of animals born with this condition. Affected animals must have two copies of this mutation and therefore inherit one copy from each parent. An animal that is a CA carrier will spread the mutated gene to 50% of their progeny.
