Oh yeah explain to me split to pied like Im a two year old and then slow it down a bit more
split to pied means that they have only one pied gene...
when a bird is visual pied, it has 2 pied genes, one came from the mother, one from the father....
when a bird is split pied, it received a pied gene from one of the parents, but a normal gene from the other...
the normal gene is 'stronger' or 'more dominant' and so masks the pied colour from the single pied gene, the outcome is a normal looking bird, with tiny patches of white or yellow showing through in random spots(because the pied gene can not be completely hidden by the normal)...
if you breed 2 split pieds together you produce 25% visual pied birds
because the split pied have one pied (p) gene and one normal

gene...
pn + pn when the baby is conceived it receives a half genetic code from each parent, so the baby can receive either a p gene or a n gene from each parent...
possible outcomes are pp, pn, np, and nn
so therefore 25%normal 25%pied and because pn and np result in the same thing 50% split to pied!
