  1. Making a Face How chromosomes make us, us!

  2. What makes you, you? • Do now: • On your index card: • What are genes? • Where are genes located?

  4. Vocabulary • Gene • Chromosomes • Inherited Traits • Acquired Traits • Genotype • Phenotype • Sex Cells

  5. Gene • Piece of DNA that codes for a specific trait

  6. Chromosomes • DNA that is coiled up so that it is easier to move from cell to cell.

  7. Inherited traits • Features that are only passed down to offspring through DNA. Cannot be changed

  8. Acquired Traits • Features that are not passed through DNA • Ex. A scar on your leg or a new hair cut

  9. Which are inherited and which are acquired? • Hair color • Eye Color • Hair style • Callus on your finger • Nose shape • Bigger muscles from working out • Scar on your arm • Ear size

  10. Genotype • The combination of genes you receive

  11. Phenotype • The features that result from your genes Red Red White

  12. Sex cells (gametes) • Sperm cells and egg cells only have half of the DNA of our regular cells • When they come together, they will make a complete set of chromosomes for the new offspring • ½ DNA from mom + ½ DNA from dad

  13. Make a Face • Step 1 • Cut out your chromosomes and fold each in half lengthwise. Be careful to cut on the correct lines. • Follow Mr. Tran’s Example! Cut the highlighted parts. • Glue the halves shut with a glue stick • Place chromosomes in the plastic bags provided and label with your name and period. • DO NOT LOSE YOUR CHROMOSOMES • They will be used to make the unique combination of DNA for your child
