Presentation transcript:

CHAPTER 11 GENETICS Genetics is the study of how traits or characteristics are inherited. Inherited characteristics are controlled by genes and are passed on from parents to their children. Non-inherited characteristics are not controlled by genes but are learned or acquired during life.

CHAPTER 11 GENETICS Chromosomes are located in the nucleus of a cell. Chromosomes are made of DNA and protein. Genes are located on chromosomes.

CHAPTER 11 GENETICS Genes are short sections of DNA which control the production of a protein. Human cells have 46 chromosomes made up of two sets of 23 inherited from each parent.
