Slide 1 - Diapositive
Basics of heredity
Gene: part of your DNA with info on one trait
You get one set of genes from your mom and one set of genes from your dad
For every trait you have two genes (pieces of info)
These pieces of info can be different variations of the gene
The combination of the two pieces decides what that trait will be for you
Slide 2 - Diapositive
Example:
Trait : Hair color - brown
Gene : part of the DNA carrying the info for this trait
Variations in this gene: blond, brown, red, black
Mother's hair : blond x Father's hair : brown
