Guinea Pig Dihybrid Cross tape onto pages 139-140.
Welcome Back!! Hope you all had a good break but now back to reality! It is going to be a BERRY-full day!! Design a Species due Friday.
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.
- You will be smashing the strawberries. Be careful not to break the bag.

Happy Spring Break!!!!
Watching a Bill Nye video.
When you are done with the mid-term,
Click here -- enter your ID # for the username and the password.
Click on Student-at-a-glance (on the left of the screen). Click on your name, and then assignments. Your classes should come up on the middle part of the screen, click on assessments under Biology, and then take assessment. You should be able to enter your answers there. Once complete, click save and then submit.

What do the symbols mean on this pedigree? When the symbols are shaded in?
The objective for today:
- Do pedigree problems.
- Review meiosis.
- DNA vocab- what words?
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.
- Watching video about pedigrees.
- White boarding problems in groups. Work through the problem together.
- MID-TERM ON THURSDAY
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!!!
NOTEBOOK CHECK ON MONDAY!!! TEST ON THURSDAY!!!!
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.
Bell Work ( on page 126)
What is the difference between genotypic and phenotypic ratios?
Today:
- We are learning about sex-linked traits
- We are learning about genetic carriers.
- In pairs you will be building an offspring.
On page 130
- Top Half: vocab words :sex-linked and carrier
- You will be in pairs: each person will flip a coin to see what traits your offspring will have.
- On the bottom half of the page write genotype and phenotype of your offspring.
Page 131
Draw your offspring.
BW -- pg 126
We have been learning about Mendel's experiments with pea plants. Biologists use plants all the time.
- Why?
The objective for today: Tape onto 127 and 128
- We are dissecting flowers today.
- Be able to identify the parts of the flowers.
- Answer the questions.
- Use the dissection microscope to view the parts.
- While you are looking at the flowers, look at the phenotype. Do you think it could be codominance or incomplete dominance?
- What could the genotype be?
Second part of class: Tape 129
You are starting "Design a Species"
- Work in groups of 2 or by yourself.
- Go over instructions.
