Genética y comportamiento

In 1959, Siberian scientists conducted breeding experiments with silver foxes to study the impact of selective breeding on behavior. One experiment aimed to tame foxes by breeding the meekest individuals, resulting in domesticated foxes over generations. Another experiment focused on maintaining aggression, revealing that behavior differences are genetic. Embryo transplants confirmed that aggression is genetically inherited. These studies highlight how selective breeding influences both physical and behavioral traits.

How did the transplantation of embryos from aggressive mothers to tame mothers contribute to the understanding of aggression in foxes?

What complexities are involved in understanding the genetic basis of meekness in foxes?
