Recessive Dominance Index
Coming from breeding Amaretto I focused in the first weeks on the number of traits at the cats.
But soon I realised that the number of traits is only half of the story, if not less.
After time of reading about dominant and recessive I now think the difficulty is to breed recessive traits and I started to think about a way to score how recessive a trait and the sum of all traits of a cat is. So I started my spread sheet and begun to calculate :-)
My idea on rating the traits is: Fur 30% / Eyes(colour) 30% / Shade; Tail; Ears; Whiskers and Whiskers Shape 8% each (half shown and half hidden trait, so fur is 15 + 15)
Mathematics (Eyes as an example): I use the dominance list from Saga. I divide the %-number by the number of different eyes, lets say 75, this means 15/75=0.2 This way one step in direction of recessive counts 0.2, the most recessive eye will always be 15 and a cat with all the most recessive traits in the list will be 100 (like 100% recessive).
Now my questions: Does it make sense to do such an „index“ ? If so, is the above mentioned %-allocation ok or should it be different ? I am aware that the „index“ of a cat can change with every change of the list, so with every new eye, fur etc, but these changes will not be dramaticly.
Looking forward to your opinions (sorry for my English, I am not native English)
