Inheritance & Evolution

Creating cells

• Mitosis: creating normal cells

- Same DNA

• Meiosis: creating sex cells

- Half the DNA

- Other half will come from 
other parent

Basics of inheritance

• 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

Our dragons

1. Collect the genes of each parent
2. Determine their traits
3. Create sex cells
4. Create baby
5. Determine traits baby

Collect genes of each parent

Determine traits

Look up their traits

Example: Aa means breathes
fire

Create sex cells

Circle the one you got on the paper

Create baby

Place the gene you took from mom with the same gene you took from dad. Fill in for genotype

Example:

Determine traits baby

Look up the traits of the baby

Example:
