SUPERHERO GENETICS

Before you begin you must define the following on this page in your own words AND give an example

OBJECTIVE

Students will design a new superhero using their understanding of genotypes, punnett squares and probability.

STEP ONE-

Login to

STEP TWO-

Choose a male and a female superhero

Click on character bios and write a list of their physical traits and superhero abilities. Please choose a minimum of 6 traits for each character. Remember that traits are physical characteristics and also super hero abilities. The traits can be different for each superhero, but do note any traits that they have in common. Since we are working in pairs have one partner collect information on one hero and have the other partner collect on the other hero. This will lead to the greatest variation which is a truer picture of how genes get combined.

|  |Male |Female |

|Name |  |  |

|Trait 1 |  |  |

|Trait 2 |  |  |

|Trait 3 |  |  |

|Trait 4 |  |  |

|Trait 5 |  |  |

|Trait 6 |  |  |

STEP THREE-

Using the table below you and by flipping coins you will create a chart of your superhero’s actual combination of alleles, or genotype as well as the phenotype. You must assume that a superhero trait is dominant.

Example- The incredible Hulk is super strong

Strength is dominant

Use a capital S for strength

To determine if the hulk is homozygous or heterozygous for this trait you need to flip two coins at the same time

.

[pic][pic] =SS

If you get two heads up or two heads down then he is homozygous.

[pic] =Ss

If you get a heads up and a heads down he is heterozygous.

PLEASE COMPLETE THE FOLLOWING DATA TABLE – LOOK AT HOW I DID THE HULK IF YOU ARE CONFUSED

So let’s pretend I flipped the coins for Hulk and I get two tails. I would fill in his genotype as homozygous

.

**TWO OF THE SAME COINS = TWO OF THE SAME ALLELES**

Remember- You choose the letters you want to represent the alleles. Like if your hero has x-ray vision, you might use XX if they are homozygous or Xx if they are heterozygous.

|Male character |Genotype |Phenotype |

|Example /Hulk |SS |Strong |

|Trait 1 |  |  |

|Trait 2 |  |  |

|Trait 3 |  |  |

|Trait 4 |  |  |

|Trait 5 |  |  |

|Trait 6 |  |  |

|Female character |Genotype |Phenotype |

|Example /Wonder Woman |Ff |Ability to Fly |

|Trait 1 |  |  |

|Trait 2 |  |  |

|Trait 3 |  |  |

|Trait 4 |  |  |

|Trait 5 |  |  |

|Trait 6 |  |  |

STEP 4

PUNNET SQUARES-

Now its time for the hero’s to have kids.

To do this you are going to have to create a punnett square for every single trait that you have listed for your hero’s. If your hero’s have traits that overlap you only need to do one punnett square. If one hero has a trait that the other does not then you should assume that the hero that does not have the trait has two recessive alleles.

|TRAIT ___________ |  |  |

|  |  |  |

|  |  |  |

Prob. of getting trait ____:____ actually received trait Y or N

To determine if they get the trait flip a coin once if the Probability is 50:50. Heads up = trait. Heads down = no trait. If Probability is 75:25 flip the coin twice. 2 Heads up or 2 heads down = trait. Heads up and Heads down = no trait.

To determine homozygous or heterozygous use two coins at the same time again like you did earlier. You only need to do this if they have the trait. Otherwise they will be HO recessive

Flip a coin to see if your offspring is male or female. Then use the data from above and fill out the following table.

|OFFSPRING |Genotype |Phenotype |

|Trait 1 |  |  |

|Trait 2 |  |  |

|Trait 3 |  |  |

|Trait 4 |  |  |

|Trait 5 |  |  |

|Trait 6 |  |  |

|Trait 7 |  |  |

|Trait 8 |  |  |

|Trait 9 |  |  |

|Trait 10 |  |  |

|SEX |XX or XY |Female or Male |

STEP 5

ON A SEPARATE PIECE OF PAPER

Now comes the fun part. You need to create a visual representation of your superhero that displays the traits received from the table above. Please be as neat as possible. The best option would be to DRAW the hero yourself. You may also try to use Marvels superhero generator. You can find the link on my blog. Keep in mind they may not have all of the characteristics you need, which is why a hand drawn picture is preferred. Please use an entire sheet of computer paper.
