In many endotherms, shivering occurs in cold conditions whereby the body undergoes rapid muscle contractions without any locomotion.

When the body temperature falls, brown fat cells increase their metabolic rate, and hence heat production.

X-Linked Dominant Traits

X-linked dominant traits affect both males and females. 

Although they often appear more frequently in females than in males.

Affected males must have affected mothers (unless the males possess a new mutation), and they pass the trait to all their daughters.

Affected daughters must have either an affected mother or an affected father.

X-linked dominant traits do not skip generations.
