,  What is Genetics?

 Genetics is the scientific study of heredity.

 What is a Trait?

 A trait is a specific characteristic that varies from one individual to another.
 Examples: Brown hair,blue eyes,tall,curly

 What is an Allele?

 Alleles are the different possibilities for a given trait.
 Every trait has at least two alleles (one from the mother and one from the father)
 Example: Eye color - Brown,blue,green,hazel

 What are Genes?

 Genes are the sequence of DNA that codes for a protein and thus determines a trait.




 Gregor Mendel

 Father of Genetics.
 First important studies of heredity.
 Identified specific traits in the garden pea and studied them from one generation to another.

 Mendel’s Conclusions

 Law of Segregation - Two alleles for each trait separate when gametes form,Parents pass only one allele for
each trait to each offspring.
 Law of Independent Assortment - Genes for different traits are inherited independently of each other.
