Determining Offspring - (1/3 - 1/6)

Summary: 

     The Punnett Square is used to determine what phenotypes and genotypes an offspring will receive from their parents. This square is made up of a 2 x 2 grid with the genotypes at the top and left of the grid. To use the Punnett Square select a trait to begin with. Then put one parents genotype for that trait above the Punnett Square and the other parents genotype to the left of the square. Make sure each letter in their genotype aligns with a square. Then, to fill the square, simply take one letter that is aligned with that square and put it inside it. Then take another letter that is aligned with it and put that in the square. Do this for each square in the Punnett Square and now you have a table full of genotypes that will determine the probability of the offspring getting that trait.

SP6 - Constructing Explanations: 

     I constructed an explanation of what the offspring of my superhero, Invisib-blend and Black Widow would look like. To do this, I used a sheet prior to this activity that determined Invisi-blend and Black Widow's genotypes for each trait. Using that sheet, I filled in 10 Punnett Squares to determine what traits the offspring will receive from each parent. I found out that the offspring of Black Widow and Invisi-blend will have a tail, 360 vision, claws, no scales, red hair, stronger immunity, but will not be fast or blend in. The child is also a tactician. The last two things that I determined were the superhero status and the gender. I found out with the Punnett square that the offspring will be a male villain.


XCC - Structure and Function:

     One structure and function system I found was with a simple DNA strand. The structure of DNA supports its function by staying compact. If a single DNA strand were to be stretched to its maximum size, it would stretch to 9 meters, or about 10 feet. However, that is not the case, as DNA is shortened down into an extremely compact size smaller than a cell. Since the DNA structure is extremely small, it could work to its maximum efficiency since it isn't bigger than the cell it is. That same cell can easily retrieve it for instructions on what to do, when and how to replicate, etc. This is how DNA's structure supports its function.
