Many genetic studies, particularly those of recessive traits, have focused on small, isolated human populations, such as those on islands. Suggest one or more advantages that isolated populations might have for the study of recessive traits.

Concept explainers

Animal Behavior

Animal behavior can be defined as all the things that animals do. In response to a stimulus, an animal performs a certain fixed action pattern, or FAP, of behavior. This response occurs to make the animal more adaptable to change. So, behavior is generally a stimulus-oriented response. A behavior is an expression of the capabilities of the nervous system. A stimulus is determined by the environment, while the nervous system determines a response.

When you decide to breed your Labrador retriever Molly and sell the puppies, you discover that two of Mollys four siblings have developed a hip disorder that is traceable to the action of a single recessive allele. Molly herself shows no sign of the disorder. If you breed Molly to a male Labrador that does not carry the recessive allele, can you assure a purchaser that the puppies will also be free of the condition? Explain your answer.
