a properly laced bird must be homozygous for 3 separate mutations. the Pattern geme (Pg), the Columbian gene (Co) and the Melanizing gene (Ml). the diagram below shows what birds that are homozygous for columbian exhibit, when the other genes are heterozygous (only carry 1 copy of the gene needed) for either or both of the other mutations.
if you look at the diagram below, the top right image shows the wider lacing, indicating that these birds are heterozygous for the pattern gene, while the lower right image are birds homozygous for all 3 genes required for proper lacing...

Based on what you see in the hen above, would you say that she is heterozygous for the pattern gene?
If so, then I believe that I have one hen with the correct pattern (bottom right picture) one with a pattern similar to the bottom left picture, and the rooster is heterozygous for the pattern gene (top right picture). I have 3 more silver chicks growing out and I don't know what they'll be. How will this affect my breeding? Which are dominant?
Is there a website or book that explains this?
