Dimorphic and Dilute

[Berd Man]

So I’ve been playing with these color calculators off and on this season. I like it, but I keep getting hung up because I don’t know the definitions as well as I should yet and the photos on the calculators are not great to compare to real birds…forgive me for asking repeated questions about this topic if it’s annoyed anyone…

so anyways … I bred and embden gander to a group of buff females and embden females. Obviously the embden x embden are white birds (or mostly white anyways these are hatchery quality so there’s a grey feather here and there).

The Embden x Buff gets a little more interesting. The calculator says male offspring are “dilute” and females are “dimorphic”. Does this mean males are buff and females mostly white or spotted? I have some photos below to give an idea what the birds look like. I put arrows going to different looking goslings.
I understand buff is dilution of grey. But what is dimorphic? Just differences between male/female?

This article explains it with snow geese.

To quote: The lesser snow goose is dimorphic, which means it comes in two different colors phases, a white phase and a blue phase.

Dimorphic. when connected to sex is 2 different colors attached to sex of bird. when bred together all boys will be x color all girls y color or pattern. Like Mallard ducks but you can only see the color difference with them during breeding season.

Sex linked is a bit different. Its when the color can only be thrown by the boy to the girls. For instance breeding a buff boy to a brown girl all girls are buff all boys are brown. But now thous brown boys will carry the buff color and can throw it to both boys and girls when bred back to buff.

Chocolate in ducks is a sex linked color.

Whites are never white genetically. They are both dimorphic and Pied. this hides there color so you only see white. Not all white ganders are dimorphic and pied. some are just dimorphic.

Embden hides allot of Blue genetics.

Just guessing blue one is a lilac dilute. Red looks buff or buff pied. Green looks ether blue dilute or Silver. will be interesting to see them feathered out.


dictionary

PS when you pick your choices on the calculator on your white boy on the 3rd choice down pick blue

Okay I see now that the dilute blue comes into play now when the calculator for the embden is done right. This makes sense with what I’m seeing. I have several goslings that are buff, more are white or white with grey. Very few are that light dilute lavender color. Thank you again!

I was helping my friend Don figure out where his blues were coming from. He wrote a top breeder and then that's were we figured out the blue gene. To get white Africans some have bred into the white Chinese that's were my white gene came from. His flock was bred into the Embden which carry the blue gene. The blue gene can bring in lots of cool colors. allot of your buffs will have white feathers that's the pied

I saw a photo of one of your white dewlap Africans and it was really beautiful. There’s an Australian fella, Michael Peele, that has made white dewlap Tolouse.

I am growing out some Dewlap Buff Tolouse this spring and want to see if I can get some of these spectacular colors with an embden in the line. I would have to then figure out the inheritance of the dewlap features though.

Speaking of African geese, if a buff male breeds a normal female does he throw buff to the female offspring? I saw three buff goslings mixed in with some of my other African cross geese and I sexed them today and all three were female.

Nvm you spelled it out right here haha

pure buff male (who dose not carry brown) to Brown girl. all girls buff all boys brown. Brown boys will carry buff when there bred to buff they throw 75% brown boys and girls 25% buff boys and girls thous buff boys can be split.
