Peafowl 201: Further Genetics- Colors, Patterns, and More

[WestKnollAmy]

Now that is a very interesting discussion. I never thought about it before.

Subscribing. Super interesting!!! I'm trying to wrap my brain around the genetics discussed here and it is making my brain feel very pretzel-like. I have some questions but will try to get a better grasp prior to asking my silly questions. Awesome posts!!

If you are up reading in depth about it, there's a couple more old threads that discuss things at quite some length. I'm still trying to wade through them -- I had read some before, but found others tonight that I hadn't seen:

These are great! Thank you! Will keep reading. I understand the basics of genetics and even genetics of many chicken colors. Just trying to orient myself to peafowl genetics, particularly how white and pied are carried and passed down. This site is fantastic as are all the wonderful people who post & discuss these topics! Thx!!

You know, one of the things this brings to mind is the question, "how many white eye genes does it take to make silver pied?"

If I am recalling correctly, white eye is a bit different from some of the other genes we deal with, in that there is some kind of dominant or incomplete dominant effect. As I understand it, when a bird has even one copy of the WE gene, it will show some white eyes in the train or other markings (such as the silvering), so it doesn't stay hidden like many of our other traits do when there's only a single copy. (The other gene that comes to mind is black shoulder -- some of our black shoulder splits sometimes show funny shoulder markings or coloring, even when it's a split rather than 2 copies of the gene.)

I've been wondering for awhile whether having one copy of WE (or perhaps one copy of a mutated WE, if that's correct for SP), may be enough to cause silvering, but perhaps not as extensive a silvering as happens if the bird has two copies?

Spalding ancestors ! A half green wing coming from green blood.




Surely a Silver pied!

The genetic origin of this bird proves that what says Peas Garden is probably true!

As I said..... he is a Silver Pied fathered by a Pied male with no silvering (but probably carrying 1 White eye gene) and a mother who is Silver Pied. I have another pair just like this and they also produce Silver Pieds. This tells me that having 1 parent with silvering is enough to give silvered offspring.

The first link of Garden Peas :

With the sexlinked colours it would seem "easier?" (Maybe not the right word) for a mutation to become apparent. Since the male only has to have one mutated gene, it would occur more frequently than let's say a pairing of midnight mutant carriers. This might explain why cameo has occurred as a mutation more than once (sorry, history of mutations as listed on a breeders site, as well as photos of a wild cameo hen in India - originally linked by minxfox). The non sexlinked ones have mostly been found in captive flocks, where inbreeding likely occurs in higher %s

Augeredin :
Bingo! You are exactly right. It is actually highly likely that other mutations exist that are not sex linked but they never were bred in a closed group to get split offspring bred to each other or the parent.

Just the opposite! .... only one gene and the female has the sexlinked color !

They use to say that white color is lake of fixation of color . In fact white peacock are genetically .... Blue .... Cameo or Blue BS.
White is also a " degeneration " of the quality of the feathers .... size of eyes ... etc . ( .... not always ! ).

Dany12,

Please explain what makes this a Reverse Pied over being a Silver Pied. No silvering? No white eyes?

Or would this also be what is referred to as a Loud Pied?

Trying to learn here, since these are the colours I am interested in. Have not heard the term Reverse Pied before.

And my 4 week old Silver/Reverse/Loud Pied chick displayed for me this morning when I went to play with him/her...Very very cute.

Reverse Pied is the US version of a Pied. They're missing the White Eyed gene to make them Silver Pied.
