Yes. Bell had an interest in the emerging science of heredity, and later genetics, as it applied to livestock.
In the 1890s, Bell began three decades of observing and recording experiments in sheep breeding on his estate in Canada. He hoped to develop sheep that were more likely to bear twins in order to make the flocks more productive for local shepherds.
The mechanisms of heredity were poorly understood in 19th Century before the experiments on pea plants conducted by the renowned scientist Gregor Mendel became known among the scientific community after the spring of 1900.
A clear understanding of the basic rules of genetics and heredity would not emerge for decades after Bell’s death in 1922.
