Mutations.

http://biologypop.com/dna-mutation-info/

Have you ever wondered how the differences in our genes com about? The answer to that question is Mutations. Mutations are when your genes are copying the DNA before cell divisions certain mistakes or typo's are made. This is very common in people. Because of Mutations we have 60 different things our parents didn't have. Some versions of Mutations are when the cell adds another base which is called an Insertion Mutation, deletes a base which is called a Deletion Mutation, or substitutes a base for another which is called a Substitution Mutation, or it shifts the DNA over one which is called a Frame shift mutation. Mutations could be good or bad depending on where they are found. But most of the time they are neither  good or bad just different. The only kind of Mutation that will or could be bad it a Mutation in the cells that make and control the proteins your body produces. Sometimes these Mutations can be passed down to children. Sometimes Mutations have no or little effects on you or the way you look. Other times they can have big affects. Most ways that mutations happen are natural but sometimes they happen because the thing has been genetically modified. You can see many genetically modified things in foods.

I constructed an explanation of Mutations when I came up with ways my superhero that I created got mutations that turned her into the superhero that she was. I also explained it when I made my came up with reasons why her DNA was changed and how. I finally explained it by adding what type of mutation she got.

Non-Mendelian Genetics.

Have you ever wondered why animals and plants can be multiple colors if Mendel thought that they could only be one? Or why some animals have two different colored eyes? This is called Incomplete dominance or Co-dominance. Incomplete Dominance is a blending of two different Dominant traits that make a third trait that is a blend of the two traits. The third trait is the trait that will show up. Co-dominance is when the two original traits ore combined to make a multi colored or spotted trait/phenotype. This is called non-Mendelian genetics because Gregor Mendel thought that their could only be a recessive and a dominant trait and that their could not be two of a certain trait. The puppy (above left) and the flower (above right) are two examples of this. They are both an example of co-dominance.

I explained Non-Mendelian Genetics through my notes in class because I made sure that everything that I wrote I understood. Also so that I wrote down everything that I felt explained Non-Mendelian Genetics so that I could fully explain and understand Non-Mendelian Genetics.

Guessing genetics

Have you ever wanted a certain breed of dog or pet? Have you ever wondered how they got that dog to be that certain breed? The answer is cross breeding. Many pet shop owners do this. Where they take two dogs of two different breeds and cross breed them. But how do they know what results they're going to get and if they are the results they want? They use the punnett square. The punnett square was invented by Reginald Punnett. The Punnett square is used to organize the chances of your pet getting to be the breed you want it to be. But once you get your punnett square how do you know what the breed will be?

You would know because 75-100% of dominant will mean it will probably get the dominant trait and 75-100% recessive will mean it will probably get the recessive trait. If it is 25-50%  dominant or recessive they will probably try to breed the animal with a different one of that animal. Usually that will happen to all of the traits and they will decide if they need to breed it with a different type depending on what percent is the trait they want. They do this till they get the breed they want. This method can be used to determine and guess any living things traits.

I made a model of the data that I collected throughout my experiments when I made a drawing of what my superhero's traits would look like. She would have super strength, can climb, can fly, and has super speed. I drew all four of these traits. It also helped me see more of what my superhero would be able to do and pulled together everything that I had collected over the course of finding out my superheros traits using punnett squares.
