So the mom goes on the top and the dad goes on the side.  Lowercase letters are recessive and uppercase letters are dominant, so you only need one capital letter (dominant allele) to see that trait, but you need two lowercase letters (recessive alleles) to see the recessive trait.  It's actually really simple (I learned it in the 7th grade!). That's all for this exciting post, I promise the next one will be more complicated/exciting!
