1. Warm Up 1. What type of inheritance is shown? all three have the same:
Population 3 – 50% Red fish and 50% striped fish
Population 1 – 100% White fish
Population 2 – 100% Striped fish
1. What type of inheritance is shown? all three have the same:
( Mendelian / Incomplete dominance / Co-dominance / Lethal)
(Use your flow chart from yesterday to find out!!!)
What are the three phenotypes present?
(Look at the fish, and write down the three types you see)
3. What gene symbols (letters) should you use to represent each phenotype?
(Use your notes from yesterday to find out!!!)
4. What are the genotypes of the fish in each population?
(Match your answer from #3 to each population of fish)

2. More Practice 100% white fish B) 100% red fish C) 66% red fish &
1. Mode of Inheritance
2. Gene Symbol (Letters) for each phenotype
3. Parent cross that gave us population A)
B) C)

3. Mendelian and Non-Mendelian Inheritance Stations

4. Pre-Lab Mendelian Co-Dominance Incomplete Dominance Lethal Allele
Number of phenotypes for a single trait?
How do we write / represent the alleles?
Extra / Added information?

5. Example – Together as a class
What type of inheritance is shown?
What gene symbols (letters) should you use to represent each phenotype?
3. What parent cross led to this population?
25% red, 25% white, 50% striped

6. Station 1 What type of inheritance is shown?
What gene symbols (letters) should you use to represent each phenotype?
3. What parent cross led to this population?
Prove it with a Punnett square
Half pink, half maroon flowers

7. Station 2 What type of inheritance is shown?
What gene symbols (letters) should you use to represent each phenotype?
3. What parent cross led to this population?
Prove it with a Punnett Square
All speckled

8. Station 3 What type of inheritance is shown?
White Horses
Brown Horses
Tan Horses
What type of inheritance is shown?
What gene symbols (letters) should you use to represent each phenotype?
3. What parent cross led to this population?
Prove it with a Punnett Square
All Tan Horses

9. Station 4
Brown
Grey
What type of inheritance is shown? (*Hint – look at population ratios for number 3 first!)
What gene symbols (letters) should you use to represent each phenotype?
3. What parent cross led to the population?
Prove it with a Punnett square
2 Brown,
1 Grey

10. Station 5 What type of inheritance is shown?
brown puppies
Brindle (striped tan and brown) puppies
Tan puppies
What type of inheritance is shown?
What gene symbols (letters) should you use to represent each phenotype?
What parent cross led to this population?
Prove it with a Punnett Square
Half tan puppies and half brindle puppies

11. Station 6 What type of inheritance is shown?
All white
All Red
6 red, 2 white
What type of inheritance is shown?
What gene symbols (letters) should you use to represent each phenotype?
What are the phenotype percents (or ratio) of the organisms in each population?
4. What parent cross led to population 3?

12. Station 7 What type of inheritance is shown?
All white
Half Red, Half white
4 red, 2 white
What type of inheritance is shown?
What gene symbols (letters) should you use to represent each phenotype?
What are the phenotype percents (or ratio) of the organisms in each population?
4. What parent cross led to population 2?
