1. Bikini Bottoms Genetics
Remember your definitions. If something comes up look back to the genetics notes
Complete the Bikini Bottoms Genetics Worksheet (get from the teacher)

2. Genetics

3. 1st day of GEnetics

4. Who is Gregor Mendel?
Watch:
Make sure you know:
Who is Gregor Mendel?
What was Gregor Mendel’s background?
What was Gregor Mendel’s contribution to science?

5. Use a Highlighter to review the pre-printed genetics notes
As you go through, jot down questions you have.

6. Basic Genetics
On a piece of paper, write the following terms and then describe the relation between or the difference between the terms.
DNA, gene and allele
Dominant vs. Recessive
Phenotype vs. Genotype
Heterozygous vs. Homozygous
Purebred vs. Hybrid

7. 6 possible crosses Punnett Squares Complete the 6 possible crosses
Watch:
Complete the 6 possible crosses
Both Parents are Dominant
Three ways both parents could be dominant. What are they?
Both Parents are Recessive
One way both parents could be recessive. What is it?
One Parent is Recessive and the other is Dominant
Two ways one parent could be recessive while the other is dominant. What are they?
Once you’ve the Punnett Square determine the phenotypic ratio
Phenotypic ratio is the ratio of dominant offspring to recessive offspring.
It is Written # of dominant : # of Recessive

8. Genotypic vs phenotypic ratio
A genotypic ratio is the ratio of RR : Rr : rr
A phenotypic ratio is the ratio of Dominant: Recessive
Complete a Punnett Square for a purebred brunette and a hybrid brunette
Then write the genotypic and phenotypic ratios

9. What is your Genotype? worksheet
Pair up with a partner that you don’t mind playing with your hair…
Together, Flip through the “What is your Genotype” Power Point that is linked on the website. Determine if you are Dominant or Recessive for the traits and complete the worksheet.
Once you have determined your own traits and filled out the front of your own worksheet, work together to complete the back of the worksheet.

11. Penny for your Probability
Each time MEIOSIS creates a sperm or egg cell, the product is a flip of the coin.
If an individual is heterozygous: Rr; there is a 50% chance the gamete will receive a ‘R’ and 50% it will receive a ‘r’
Each fertilization is unique and does not affect future mixes.
Does the existence of prior offspring affect the probability of traits in future offspring?
Example: Complete a Punnett Square for two individuals- Rr and rr
1. What is the phenotypic ratio of the cross?
2. What is the genotypic ratio of the cross?
3. What is the chance their child will be rr?
4. If the couple has a second child, what is the chance he/she will be rr?
Complete the Penny for your Probability Activity with a partner (you will need a worksheet from your teacher)

If you don’t remember, go back and watch the video which is a few slides back.

14. Complete the practice problem below on a piece of lined notebook paper then check your answer on the next slide
1. Set up a punnett square using the following information:
Dominate allele for tall plants = D
Recessive allele for dwarf plants = d
Dominate allele for purple flowers = W
Recessive allele for white flowers = w
Cross a homozygous dominate parent (DDWW) with a homozygous recessive parent (ddww)
What will the offspring look like?

15. ANSWER
All offspring will be heterozygous for both traits (DdWw) and their phenotype will be Tall and Purple flowers.

16. Complete the practice problem below on a piece of lined notebook paper then check your answer on the next slide
2. Set up a punnett square using the following information:
Dominate allele for black fur in guinea pigs = B
Recessive allele for white fur in guinea pigs =b
Dominate allele for rough fur in guinea pigs = R
Recessive allele for smooth fur in guinea pigs = r
Cross a heterozygous parent (BbRr) with a parent who is (BBRr)

20. Polygenics Watch: https://www.youtube.com/watch?v=gouqTq5p168
Brainstorm 10 traits and check
Polygenics with your neighbor and come up with a list of traits you think could be polygenic
Then research them on the internet and determine if your brainstorming produced any.
Make sure you have ten traits written down and then next to them affirm or reject them as polygenic traits

21. Multiple Alleles Watch: https://www.youtube.com/watch?v=3XmYVF0rwKU
Discuss Multiple Alleles with your neighbor then together complete the question below
The possible genotypes of a man with blood type B are BB or BO and the genotype of a woman with blood type AB is AB. The child would receive an A allele or a B allele from the mother and a B allele or an O allele from the father. Complete BOTH possible Punnett Squares for the two individuals offspring. Then check your answer on the next slide.

22. Child could Potentially Have A, AB, or B Blood Type
ANSWER
Child could Potentially Have A, AB, or B Blood Type
A= A blood type
B= B blood type
i= O bloodtpye

23. Today you’ve studied exceptions to Mendelian genetics
Non-Mendelian Genetics are things that are not as straight forward as dominant and recessive.
Examples of this are Multiple alleles, polygenics and the next two:
Codominance- Spotting
Incomplete Dominance- Blending

24. Codominance = Spotting
If you have two distinct traits that are not completely dominant, but instead codominant, they will share equally and you will see spotting in the phenotype.
Examples of this:

25. Codominance Practice
1) Cross a white chicken with a black rooster.

26. answer 1) Cross a white chicken (WW) with a black rooster (BB)
Answer: 0 Black: 0 White: 4 Speckled

27. Now cross the f1 generation from the previous example… yes its incest
RW x RW

28. answer 1) Cross a speckled chicken (BW) with a speckled rooster (BW)
Answer: 1 Black: 1 White: 2 Speckled

29. INCOMPLETE DOMINANCE
If you have two distinct traits that are not completely dominant, but instead incomplete dominant, they will bleed into one another and you will see blending in the phenotype.
Examples of this:

30. Incomplete dominance Practice
1) Cross a white flower with a pink flower

31. answer 1) Cross a white flower (aa) with a pink flower (Aa)
Answer: 0 Red: 2 White: 2 Pink
