  3. Today • I can describe dominate and recessive traits.

  4. What is genetics? The study of heredity developed into a science

  5. What is an allele? • The different forms of a gene

  6. Compare dominant and recessive • Dominant- will show their affect on phenotype whenever they are present • Recessive—will only show their affect when two of them for a trait are present in the genotype.

  7. Punnet square • Look at page 47 • Lets walk thru this problem • Practice Problems
