Last week my female amel motley that I bred to my male butter stripe gave me 16 good eggs. I know they will all be amel, het. caramel (butter). However, how will the stripe and motley genes interact? My understanding is that I will get some type of motley striped for sure, but will I get pure motleys and pure stripes? Or just some type of aberant mix? I cant wait til late July!!!

Thanks!!

Yes, they should. You should see about 1/2 Mots and about 1/2 Mot Stripes.

An F1 generation would be very interesting indeed in the future.

Actually won't they all be genotypically stripe motleys, because they will all have 1 copy motley from mom and 1 copy stripe from dad. However some will just look like plain old homozygous motleys and some will have a more striped look, but still mostly motley looking anyway.

None of the resulting offspring will be genotypically "pure" striped (two copies of striped gene) nor phenotypically will they look like "pure" stripes.
These results are because the stripe gene and motley gene are different alleles that are at the same loci, and therefor interact. While they are both recessive genes in relation to the wild type, they are basically co-dominant or incomplete or "shared" dominance in relation to each other with the motley gene tending to have slightly more influence in the phenotypical result or how they look when having one copy motley and one copy striped. Hope this makes sense and helps.

Thanks Guys. Thats what I was thinking, more abherant motley stripes with no pure mots or stripes really in the litter. The goal is obviously in breeding hold back females to dad who is the striped butter, and sibs to each other. I think motley striped butters would look nice!!
