Chromosome 15:

SexThis chapter introduces to us two different diseases: Prader-Willi and Angelman's syndrome. Both are gentic diseases and both are caused by the lack of chromosome 15. Inheriting these diseases depends on what parent carries the gene. Prader Willi comes from the father while Angelman's comes from the mother. This is linked to "sex" because it demonstrates the power of paternal genes. These diseases are inherited sexually and so therefor this chapter's name is sex. The mother and father have different controls over different inherited genes. This book tells us that the mother's genes have control over the cerebral cortex and the dad has control over the hypothalamus. According to this we know that we generally inherit our mom's way of thinking and our dad's moods.
