Same bird, but sides of head are totally different. Whats the explanation

 

this is very common in the different pied mutations

Yes This is perfectly normal for a pied.

 

This is Ringo with one blue and one white patch.

 

Pie her dad has one blue patch and one half blue / half white (it only shows as a half patch)

The pied mutation comes about, because certain areas of the body have no pigment (or crystalline structure in the case of birds), thus the side where the cheek patch is white, is a side that has been pied and the side with a blue cheek patch is an unpied side. :offtopic:

Thank You all very much. So the idea is sort of like a halfsider....pied/non pied? I am trying to get this genetics stuff, really I am!! It's sinking in a wee bit at a time, so thanks again for being so patient with the *New kid*.....(Laughing out loud)

haha, now halfsiders are something completely different once again. Halfsiders can be two things: a tetragametic chimera or some else that is wrong with the pigment. Tetragametic chimeras are when twins are initially formed, then one is reabsorbed by the other when they are only a few cells big and thus the animal has two different sets of DNA

A Pied bird is a common type of mutation that just lacks pigment in certain areas, at random, whereas, as Sailorwolf says, halfsiders are birds with two separate DNA’s fused, quite rare. Pieds when mated together can reproduce their mutation, but I don’t think halfsiders can.
