Dark lavender vs lite lavender

[Henk69]

Hello,

Is it known which one of the two (dark and lite lavender) is dominant when you cross these 2 colors?
And if the dark variant is dominant, does it also have a darkening effect if you cross with pearlgrey/wildtype or other colors?
Thanks in advance...

Your guess would be as good as mine. When I read about genetics it makes my brain hurt.
If I do understand what its talking about I usually break it down to where others and I can understand it better.

The Lavender color is dominant over Lite Lavender, but both can show up in the hatches, depending on if the Lavender is carrying the recessive lite blue gene (plus other colors may show up depending what both birds are carrying in their backgrounds). Lite lavenders carry tan and blue genes,so again depending on what the Lavender is carrying as far as hidden recessive genes, other colors may show up too.

Anything bred to Pearl Grey, even Lavender which is recessive to Pearl Grey will usually hatch out all Pearl Grey keets, (unless the Pearl Grey is carrying hidden recessive genes of other colors and pearling pattern). Pearl Grey is the almighty dominant color and degree of pearling, kinda like like a big black sharpie marker covering everything else up

OK, thanks.

Here is the problem, in Europe.

We have the following diluted colors:
lavender
lite lavender
buff (dundotte)
white (with pearls!)

No mention of chocolate in the standard, but I think it is in play too. Do I confuse it with your Tan gene?

My theory:
buff = dark lavender + chocolate
white = lite lavender + chocolate
So I used my trump card already and can not explain the difference between dark and lite.
If Tan is a separate gene then it should have it's own color.

Over here Chocolate is one of many varieties/colors of Guinea Fowl that have/show the tan gene (but in our Chocolates the tan gene is not diluted). And as I mentioned previously some colors carry both the tan and the blue genes. Most of our tan gened birds don't produce blue gene keets unless they are carrying a blue hidden recessive and bred with another bird that also has it or carries it hidden.

I'm horrible with understanding Guinea Fowl genetics (even worse with trying to explain what little I do understand), and it's really confusing especially when not all parts of the world have the same colors. We have a lot of colors over here, but our Standard of Perfection only recognizes 3 colors (which is ridiculous!). Have you checked out this color chart ?
