[QUOTE="ArmyDoc, post: 624050, member: 6832"] Thanks for the pictures! Unfortunately, I will have to wait till I get home to view them - they have photosites blocked at work. oh well. What was the color of the MG parent for these crosses? Silver, or something darker? I was thinking, if the underlying color for MG is E+ (wild type redish-black), with a homozygous diluter gene to get the silver color, then crossing with a cow with no diluting gene would be expected to have a darker coat. For a red animal, the E+ would be dominant... so the ofspring would be heterozygous, but phenotype redish-black, one diluting gene, so a bit lighter - voila: chocolate. Still working on understanding with the back angus though. If they were heterozygous black and e or E+, then the offspring could be identical in color to the reds. If homozygous black, I would have expected the dominant black would have made them dark gray with on copy of the diluting gene... Do any of these crosses have offspring? Would be very interesting to know their colors. Cool stuff though, and thanks again for the pictures. By the way, do you have a web site? ArmyDoc [/QUOTE]
