That certainly does show that its recessive to Burmilla Chocolate Silver Shaded.
For Explaination
Primrose bred a Burmilla - Chocolate Silver Shaded to a Starter and got a Toyger - Blue, Pedigree #1, which hides either Burmilla - Chocolate Silver Shaded or something more recessive.
Since the pairing had previously given a Burmilla - Chocolate Silver Shaded shown in pedigree #2 we know Thyme passed something more recessive because Fearchar passed his hidden fur both times which has to be the Toyger - Blue.
That brings the range right down on that fur, if Primrose is able to pull the suspected Burmilla - Lilac Shaded back out or if we can see a pedigree showing Thyme or her mother hide it we can nail the other end down as well
Thanks Song and Primrose
