You do NOT need to re-write the question!!

2. Today in Room 326/311… HW: Create your own punnet square problem CONTENT OBJ: SWBAT use genetics vocab in context and complete punnet square problems LANG. OBJ: SW read the powerpoint/worksheet, discuss in pairs, write notes and listen to directions ANNOUNCEMENTS: Grades updated; progress reports due. AGENDA: AS: Probability (10 min) Genetics Brainstorm (5 min) Genetics Vocab Activity (20 min) Vocab Review (10 min) Dragon Genetics (20 min) Punnet Squares (15 min) Date:5/19/16Topic:Genetics IntroPage # ___

3. Genetics What do you know?

4. Language of Genetics Genetics = Study of genes and heredity LOTS of new vocab words Will pass out the words, and you will go find their definitions around the room. You will write the definition next to the correct word. Hold onto this for your notes!!!

5. Mini Vocab Review Gene = segment of DNA (ex. hair color) Allele = different version of a gene (brown vs. blonde) Genotype = letters that represent a gene (BB, Bb, bb) Phenotype = physical features from a gene (brown/blonde) Dominant = strong, overpowering, Capital Letter (B) Recessive = weak, needs double, Lowercase Letter (b) Watch dominant vs. recessive video: https://www.youtube.com/watch?v=mnSkz8s-b44

6. Brown vs. Blonde Brown hair (B) is dominant to blonde hair (b). What color hair does the person have, based on their genotype? BB = ______________ bb = ______________ Bb = ______________ Which genotypes are homozygous vs. heterozygous?

7. Dragon Genetics POGIL READ THE WHOLE THING!! It gives you all the information you need. Complete in pairs and return to me. (Will be collected)

8. Punnet Squares Brown eyed heterozygous father Brown eyed heterozygous mother Genotypes?____________________

9. How can brown eyed people have a blue eyed child?

10. Making Punnet Squares

11. Bird Babies What percent of the offspring will be blue?

12. Practice Problems A guinea pig heterozygous for black fur has babies with a brown guinea pig. Black is dominant over brown. What are the phenotypic ratios of their offspring? (What percent will be each color?) x = ?

13. Homework Write your own Punnet Square Problem and complete it. Your answer should include a Punnet Square and a probability/percentage answer.
