Are you sure of that ????

No matings of India Blue and White will EVER produce Pied.
http://www.hopkinslivestock.com/genetics.htm

India Blue X India White ( split Pied ) will produce india Blue Pied !

IB Pied X White = 50% IB Pied; 50% White .... some of those White are White split Pied !

I'm wrong ?
To be White you need 2 genes White ... but is there birds with 2 genes White and 1 gene Pied ?
The question is ....does the White split Pied exist ?


A friend of mine get spalding Pied with this cross:
Pure green peahen X IB White cristatus coming from IB Pied.

My understanding is that, Yes....the white can be pied underneath. The white genes will just hide the pied, because white is not really a color or a pattern, it can hide both under white. So you can have a purple BS bird that is all white. Maybe I am wrong, but that is how it was explained to me.

I can't understand how it could be possible for white to be split pied, if a white bird came out from any pied breeding that means he took one white gene from each parent, so i don't see how its possible.

If white is a "Pattern" it would not be possible. However, from what I have read it doesn't really behave like a pattern, so it may be a trait apart from color or pattern and if it is, then it could mask the pied pattern. BS is also a pattern correct? And BS can be masked by white correct? This would lead me to believe that the pattern genes and the white genes occupy different places on the DNA strand. If this is the case then I would assume white could also hide the pied pattern. If this is correct the offspring from 2 pieds could take 1 white gene from each parent and also take pied genes from them, but the 2 white genes would hide everything else. The mating that @Dany12 referenced where a pure green hen X IB white out of pieds produces pieds can only be explained this way, and I have heard many times that whites out of pieds can produce pied offspring, which makes me think the pied is there, just hidden. Anyone else have opinions on this???

In the example I give the father (cristatus White split Pied) would have gave one gene white and one gene Pied to the young Spalding Pied.
Because to make a Pied bird both genes must be present !

The White and Pied mutations are alleles -- different versions of the same gene. Peafowl have two copies of each autosome (chromosomes besides Z and W, the sex chromosomes in birds). As such, each bird can have a total of two copies of this gene, in either of its three known versions -- Normal, White or Pied. A White pea will have two copies of the White mutation, and as such will have no copies of either Normal or Pied. A Dark Pied pea will have two copies of the Pied mutation, and as such can have no copies of either Normal or White. A Pied pea will have one copy each of White and Pied, and as such can have no copies of Normal.

Thus:

1) White peas can't be split to Pied.
2) Dark Pied peas can't be split to White.

The problem (as I've often said) arises from inconsistencies in terminology. Some people refer to any bird with some areas of depigmentation as "pied." Thus a pea which is split to White, or split to Pied, may be called "Pied" by some people. But what is correctly called "Pied" in peafowl is the phenotype resulting from the genotype of having one copy of White and one copy of Pied -- which are alleles.

So, where does BS fit into this? Normal would be barred wing? or normal would be No White? I thought of normal as barred wing: a pattern, others being BS, Pied, Silver Pied, are you saying white is a pattern, or that white and pied are separate from barred wing and BS?

BS genes are part of a different part of the genetic code and have nothing to do with white or pied. pied and white birds can be barred wing or black shoulder. Of course on a white bird you would not know what flavor it was as it is completely masked. Rosas reference to normal is related to a lack of pied or white markers.

White IS a PATTERN not a color.
