The Genetic Connection

• Genes are components of cells that determine the
  individual characteristics of living things.
• Genes are comprised of DNA
• DNA determines what the cell and its successive

The Genetic Connection

• Mapping is the matching of genes to certain
  traits
• Used by geneticist to determine which genes are
  responsible for certain traits
• Examples tendency of baldness in humans, height
  of plants at maturity, and tendency of females to
  have twin offspring.
