Quick Class Discussion: Remember WAAAYYYY back in the day (like 2 months ago) when we watched Photo 51 and the scientist extracted a glob of DNA. Now think about what you know about DNA and think of why it you were able to see it.
Objective for Today:
Dihybrids
Extracting DNA from strawberries (actually seeing what you have been learning about)
Lab
You will be in groups of 2 or 3.
Supplies: Rubber band, coffee filter, 10 ml of buffer solution, 1 strawberry, 1 10 ml graduated cylinder, 1 400 ml beaker, and 1 test tube and 1 pipette/straw and 1 plastic bag.

Bell Work: on page 135.. If a person who is a carrier for cystic fibrosis (recessive trait) mates with a person who has the condition, what are the chances the offspring will be carriers? Or have the disease?
Today:
Notebook check.
Tape or glue pedigree pages onto 136-137.
Finishing up "Lady Bugs": You will turn in the karyotype data table.
Today you will be watching "Cracking the Code of Life". Answer the questions about the movie in your notebook on pages 133-134 (or the next 2 blank pages you have). Monday we will finish the "Lady Bug" activity. Have a great weekend!!!
Bell Work Question: What is the term used when a person has the gene for a disease but does not have the symptoms?
The objective of today: Click here for today's presentation.
You will investigate genetic disorders.
Be able to identify chromosome abnormalities.
Vocab from yesterday: Sex Linked Traits: the chromosomes that determine whether the offspring is going to be male or female. X chromosome. Carrier: a person or organism that has the recessive alle of a mutation or genetic trait but does not show the trait or disease.
