I'm curious about the answers but I'm eager to learn about this goldust morph. As stated previously, I'm not familiar with it so I don't know what it looks like nor do I know if it is a recessive gene. I based my answer on all the traits being recessive. Neither parent had the same recessive genes, no matchup, no morph. I just used the genetics wizard and input butter, goldust, striped as homozygous recessive traits and motley as hetorozygous recessive trait. Here's what I got for that breeding:
Homozygous butter, Homozygous striped,
x
Homozygous goldust, Het. motley,
50% Het. butter, Het. striped, Het. goldust,
50% Het. butter, Het. striped, Het. goldust, Het. motley,
These are all hets, no homozygous / morph hatchlings. All normals that are hets. That is what I responded but I see that several people are responding different. How is that possible? Is the goldust morph related to butter? I checked on SMR, no info. Same for Kathys site.
