Sabrina - You are asking good questions for someone who is getting interested in hybridizing.
To show you more about parentage, I sometimes do a hybridizing pedigree chart for some of my seedlings. This particular chart is for 4 seedlings from the same cross. Dragonfly Dawn x Dragonfly Dawn seeds. The original seller/hybridizer crossed DD with itself and then was selling those seeds. If memory serves me correctly, I don't think anyone bid on those seeds except me. But I had a gut feeling about them and I was more than right. I have learned to go with my inner voice on seed purchases and what to cross with what in my daylily beds.
Here is a pedigree chart of those 4 seedlings showing their family tree (enlarge the photo to see the entire chart):
As you can see, some of the bloom characteristics came from generations previous to the parents of these seedlings. It is quite fascinating to say the least. This is one of the big reason I am such a daylily addict. I never get bored of daylilies and hybridizing.
