Hello dear Fabio,
We agree with you in many topics, we love your natural way of confronting the unknown¡¡¡
We are like you ,experts only by experiences,we have had more failures than success¡¡¡
but that is what give us some little knowledge.
First ,about breast variations we have our own theories, and they are explained in the recent articles we published in Juan facebook page.these are really controversials.
About what you say on the mask pigments,we are totally agreed with you.
and now we know more about the blue headeds, it seams they are a new variation of the melanin dilution gene,you will see new photos about them, perhaps it is producing fheomelanins instead of eumelanines,but that topic is for another day.
About the cuban seagreens , they are not obtained fron pastels (melanine dilution gene) .
We say our first seagreen (also all from other countries)came out from a crossing over between the melanine dilution gene (pastel gene) and the lipocroms wild gene (a sex linked gene that acts on other gene which is autosomic),then from this first mutated we can obtain seagreens.
Remember we have seagreens with and without the pastel gene involved,we also have seagreens together with double factor dilution gene.
We say that the melanin dilution gene(known as pastel gene or yellow gene) is the grand creator of new variations of the gouldian finch.
Why seagreens apear in any country around the world?its creator is a common gene,the melanine dilution gene¡¡¡¡
Creation day one:
any pastel green male(melanin dilution gene) mated to any green female (ofcourse after so many and many genetic recombinations),
Dm Wl x Wm Wl x
----------------- X -----------------
Wm Wl x y
Dm= melanins dilution gene.
Wm= melanins wild gene.
Wl= lipocroms wild gene.
so when this male is forming his gametes (sperm) a recombination took place and formed new genetic secuences ,
so the gene which produce some proteines controling some other melanics proteins is tranfered to the lipocroms proccess¡¡¡
it could be represented this way:
Dm Wl x
----------------
Wm Wl x
Giving as a result¡¡¡:
Wm Wl x
-----------------
Wm Dl x
Dl= lipocroms dilution gene.
here the bird is normal melanized but abnormal lipocromized¡¡¡
So we agree about not mixing with blues¡¡¡
In the blue gouldians the lipocromic autosomic secuence is now diluted in its full expression, no intermediated colours could be seen¡¡¡
we have mentioned this epistasic relationship in the article about the lipocrom dilution gene.
so a seagreen in his first lipocromic dilution stage could be represented this way ,
Dl x (bl -o)
--------- ---------
Wl x (bloo)
bl= body lipocroms (this is resuming the entire body but we know there are specific areas as the neck))
that way we can see different tonalities of seagreens, but with the blue gene it would be the final stage, only blue¡¡¡
like this :
Dl x (bl--)
--------- -------
Wl x (bl--)
is the same than a normal blue, like this :
Wl x (bl--)
--------- -------
Wl x (bl--)
About lovebirds we fully agreed with you, we are just expecting the dark factor in gouldians¡¡¡¡
how many new combinations could be obtained ,eh??¡¡
About the ino factor ,agreed, ino and breast,
independent but linked in a epistasic way¡¡¡
is shoking to some people knowing an ino can be of two differents ways, one genetically and other fenotipically¡¡¡
when they are comming fom purple breasted they are genetically represented this way:
Ino x Pb
--------- ------
Ino x Pb
but vissually they are white breasted¡¡¡¡
for us Pb= purple breasted but in two shorted processes,they are:breast feomelanization and breast eumelanization.
About the seagreen plus pastel green bird with the green neck,the funny thing is that he is white breasted and should be yellow necked?¡
because no white breasted green pastel exist¡¡¡
wishing you the best
Juan
