1. Connecting Meiosis to Genetics Biology

2. How are meiosis & genetics related? 1. Meiosis produces gamete cells.

3. How are meiosis & genetics related? 2. diploid cells become haploid cells

4. How are meiosis & genetics related? 3. Gametes unite to form a zygote

5. How are meiosis & genetics related? 4. Zygotes grow into an organism containing: 50% of the genetic information from mom 50% of the genetic information from dad

6. How are meiosis & genetics related? Genetics is the study of how the genetic information is inherited

7. A closer look at the genetic information Trait: a physical characteristic Example Brown hair Big ears

8. A closer look at the genetic information Gene: section of a chromosome that codes for a trait Example: Gene 1 codes for your hair color  Gene 2 codes for your ear shape 

9. A closer look at the genetic information Alleles: different forms of a gene an organism receives two genes for each trait The interaction of these alleles determines my phenotype

10. Analyzing Genetics A Punnett square determines the probability an offspring will receive a specific trait
