Did I do these pedigree charts correctly?

  1. I had to make 3 pedigree charts on earlobes, Tongue rolling, and ptc testing.

    I'm not sure if I did them right, can someone please let me know?

    Heres my work:


    Also it says to define the genotypes and phenotypes for each chart. How would I do that ?

    Thank you so much
