Don't feel silly, it didn't make sense to me either until I was told about Helen. I was told they used to call her the Frankenstein breeder.
Genetics is a topic I get lost very easily on, just to reply to your question i had a breeder in pm making sure I was wording it correctly, the breeding 101 group up confirming and or correcting what I thought and the glider nursery up to verify my memory was correct
I've tried to wrap my head around it and learn it but it just loses me so quickly mostly because of the lingo they use is like a foreign language to me
I get the basics of it but thats about it.
That glider nursery site has some great genetic information on it if you wander around on that site and look at all the categories, the breeding 101 group can actually teach you all that stuff if your interested in it. I try then by about the 6th comment my eyes glaze over with all the back n forth they do when they are sorting lines out lol.

Shelly Sterk runs it the glider nursery is also Shelly's site, the group is strictly about breeding and genetics, Nancy Ford, Shelly are probably two of the most knowledgeable people when it comes to genetics kinship and coi stuff..
