Yes Yaffle Honey is a combination of Yellow and Cinnamon but it is not direct and the outcome differs depending if the male or female is the yellow as yellow is sex linked. Male honeys, ppTo- and females ppToTo.
Mating a yellow male and a cinnamon female would give a litter of 50% Golden tort females (carrying cinnamon) and 50% golden males (carrying cinnamon) Mating one of the tortoishell females to a cinnamon male will then produce a litter of 12.5% golden males, 12.5% golden females, 12.5% cinnamon tort females, 12.5% golden tort females, 12.5% cinnamon males, 12.5% cinnamon females, 12.5% yellow males and at last 12.5% Honey males. A long genetic road and a difficult chance to come by!
Alternatively mating a yellow female to a cinnamon male gives 50% golden tort females (carrying cinnamon) and 50% yellow males (carrying cinnamon). Mating one of the golden tort females to one of the yellow males would then give approx 18% yellow females, 18%yellow males, 18% golden tort females, 18%golden males, 6% cinny tort females, 6%honey males, 6% honey females and 6%cinny males
Whew. Once you get there Honey to Honey is true breeding.
There are various nice combinations from honey which I wont go into unless you really need to know.
Honeys had a run of popularity about a year back and one went BIS at Bradford Champs that year. I confuse them with cinnamons on first glance
Yellows are renowned for being somewhat fiesty and firey in temperament so anything with a yellow genetic content may inherit this characteristic I guess.
Are you thinking of going honey then? Your cinny male to a honey female would produce honey males and cinny tort females but that is assuming there are no lurking genetic oddities around
