Mostroseta

The difficulty is not to become back piumaggio serico but the combination of h/h & mo/mo (reuniting 2 recessive genes) in the same chicks at the same time !
Here the percentage of that particular recombination is only 6,25 %
(+ must be counted with several other factors that may not combine in Id/Id, fm+/fm+ cr+/cr+, mb+/mb+, et+/et+, p+/p+, r+/r+ ... just to mention a few).

Out-crossing a Moroseta is almost sure to become a MOSTROSETA as Pepe always rightly calls them ;-)
BUT when one can succeed after 6 our 7 generations the ugliness will result in total fairness
