The chapter starts off talking about a five year old girl with Prader- WIlli syndrome. She shows symptoms such as being extremely obese with tiny hands and feet. It is a rare inherited disease in which children are born floppy and pale skinned. They refuse to feed off their mother's breast but later they eat as much as they can. People with this condition, tend to have small hands and feet as well as underdeveloped sex organs. They also suffer a case of being, "mildly mentally retarded."
They also mention another syndrome, Angelman's. It is when they are, " thin, hyperactive,insomniac, small headed, long jawed, and often stick their tongues out." In men, the inherited disease is carried out as Prader- Willi whereas in Women it is Angelman's.
It later moves on to point out that the gene also remember's history of its origin from the paternal and maternal instinct. In cell's where the gene is active, it often switches off between imprinted versions of the gene.
