     Have you heard of punnett squares?  Well, if you haven't, you will soon.  Punnet squares are used a lot when studying genetics, genotypes, phenotypes, etc.  They are used to determine the possible outcomes for specific genes.  For example, you could use a punnett square to see what the possibility of your child having blue eyes is.  Let's learn how they work.
     To start off, you would need to find out what genotype you and your spouse have.  Then, you would put your guys' genotypes at the top and one on the left hand side.  After that, you would list the 4 possible outcomes.  It sounds confusing, but think of it as a multiplication table, but with only 4 outcomes.  That's all the time I have for today.
