Vocabulary

Vocabulary

  • Gene

  • Chromosomes

  • Inherited Traits

  • Acquired Traits

  • Genotype

  • Phenotype

  • Sex Cells


Making a face

Gene

  • Piece of DNA that codes for a specific trait


Chromosomes

Chromosomes

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


Inherited traits

Inherited traits

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


Acquired traits

Acquired Traits

  • Features that are not passed through DNA

    • Ex. A scar on your leg or a new hair cut


Which are inherited and which are acquired

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


Genotype

Genotype

  • The combination of genes you receive


Phenotype

Phenotype

  • The features that result from your genes

Red

Red

White


Sex cells gametes

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


Make a face

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
