Danny_57, 22/08/2011 11.27: Not exactelly, look : eWh/eWh s+/s+ Co/Co mo/mo X eb/eb s+/- Co/Co mo/mo = eWh/eb s+/s+*s+/- Co/Co mo/mo Not the same genotypes but all the same phenotypes. The 2 theoretical examples concerned the "pure" ground-colorations (in this case they where based on (s+) gold) but all chickens have a ground-color (one of the possibillities on the E-locus).
