Yup, that is what I'm trying to get to. How does the letters relate to recessive, dominate and co-dominate genes.

Guys, I'm over 50 years old and like I said, my last formal lesson in genetics was in the 70's. I can put together the odds for double recessives and many combos of BP genes, but can't translate it to big and little letters.
