If that is true, we will have to abandon the dominant/recessive model and more think of it as intermediate inheritance. From one aspect, blue will still be dominant because blue x white will have some blue colour but the will (never ever????) have 100% blue appearance. That could also explain the report of two white birds having blue offspring – the parent birds have been “almost white” intermediates.

Kevin,

I could well be wrong …never worked with snow geese – but with a couple of other species which have colour morphs.

I went with the literature like

http://www.ferris.edu/card/Animals/Herbivores/SnowGoose.pdf

http://www.allaboutbirds.org/guide/snow_goose/lifehistory

I just came across the genetic of the species while looking for some research about color-morphs.

Regards from UK
Gerhard
