mustache is dominant to odyssey frazzywave
first i bred 2 specials -- mom Josalynn and dad Pslomydes -- and got a baby with mustache so one of them had mustache
then in this proof dad Pslomydes is proven to have odyssey frazzywave
mom cecelia shows double dreamy
dad pslomydes shows guitar
baby shows odyssey frazzywave proving dad pslomydes hides odyssey frazzywave as it dominant to double dreamy
with the proof that dad pslomydes hides odyssey frazzywave, going back to the first pairing, that means josalynn is the one who hides mustache as josalynn and pslomydes both show guitar.
which means mustache is dominant to odyssey frazzywave
