Punnett squares represent the mixing of genes from two parents to their offspring. A Punnett square looks like a square cut down the center vertically and horizontally. 
    I made a punnet square, also. For example, Lets call the upper left box 1, upper right box 2, lower left box 3 and lower right box 4. Above box number one, there is one gene of a parent. Each parent has a pair of two genes. Dominant genes look like this: TT or Tt. A recessive parent has only tt. So, lets say above box 1 is T and the above box 2 is a t. This parent is heterozygous dominant. To the left of the upper 1 is a t. Below that is another t. This parent is homozygous recessive. The box will show that box 1 is Tt, box 2 is tt, box 3 is Tt, and box 4 is tt. 

    One thing I struggled most was memorizing the order of Mitosis. I kept practicing and practicing, but I just couldn't remember the order! I had my dad help me, and we tried some solutions, but I didn't think they would work. On my own, I took the first letter of each stage and created a word, and that word was 'PMAT', for prophase, metaphase, anaphase, and telophase. There wasn't many questions on the test about order, but it helped to know the order for future reference. 
    The second thing was the vocabulary. The words were so confusing. I caught on to the spelling using a site called 'Quizlet'. It's a special website where you can create your own list of spelling words and then practice spelling them. My choice of learning them is using the 'Speller' option. It reads the word, gives the definition next to it, but it doesn't show the exact word. You have to type the word. If you get it wrong, it will show you your mistake and let you try again. I always continue working on the list so many times until I get 100% accuracy. It makes me happy to know that I tried so hard to learn my vocabulary, even when it gets very advanced.
