Can someone please make a Pea color chart............

[deerman]

Blue split white X Blue split white yes = white ,blues, and blues split white

with other colors you will not be able to tell the blues from the blue split.(untill you breed them) The blue split white will have white flight feathers

Ok, that makes sense.

I'm trying to make some sense of the sex linked colors... if males are the color (say, bred to blue for ease here), then female offspring will.... display it or be carriers? If I am understanding the way sex linked is supposed to work, they'd only be carriers and ALL the kids would look blue (and you'd only tell by breeding later). If the female is purple, then 50% of each gender would be blue and 50% of males would display purple and 50% of females would be carriers but look blue... Does that sound right? I think I am slowly figuring this out now.

And with splits to sex linked.... unless it was split to a sex linked color, then you'd have.... (let's say blue split opal x purple male) All females blue split opal and purple... and all males blue split opal... sound right? And say blue split opal x purple female... females blue split purple and opal and males purple.... split... opal? Or would males just be purple? I thought someone said only blue can be split colors.... but genetically they can't just drop other color genes....

I know I'm a pain in the butt... but bear with me! I'm looking at what I'm working out for 2 sex linked to be bred together... I've got purple female and peach male on my chart. So I know the males will be purple males... but the females I'm looking at 2 X chromosomes and both of them have sex linked colors on them. Does this mean they'd look blue and carry both? I think it does, but I want to make sure I 'get it'.... and I think I finally am lol

Sex Link Birds> Cameo, Purple and Peach.

I will use Purple for this> Breed a Purple Male to a Blue Hen> ALL the of the males will be Split to Purple and ALL the Hens will be Purple.

Blue male Split to Purple bred to a Purple Hen> 1/2 males Purple and 1/2 males Blue Split to Purple, 1/2 the hens will be Purple and 1/2 will be Blue.

Blue male bred to a Purple hen> ALL birds will be Blue and ONLY the males will be SPLIT to Purple.

This will be the case in all the sex linked birds.

Ok now you've completely lost me again. I was under the impression that 'sex linked' meant that the coding was carried on the X chromosomes... which would genetically mean that a purple male bred to a blue hen would be unable to produce a male offspring that displays or carries the purple... because the male contributes the Y chromosome ONLY, and therefore would not xfer the X chromosome with the coding for purple. Does sex linked in birds not work the same way as sex linked in other creatures?

So, the UPA says: "If a cameo male is bred to a blue female, the male offspring will be cameo and the female offspring will be blue. It is also exemplary that blue females cannot carry the cameo gene while males can." Is the cameo an exception? Brad Legg says: "Cameo Cock to India Blue hen produces India Blue cocks split Cameo and Cameo hens." So there's a whole wash of information that's contradicting itself @.@ No wonder people get confused.

I think I will just have to abandon the idea since I must be one of those knuckleheads Chickenzoo is talking about. It makes sense for a few minutes until someone says something.

That was a mistake on the UPA site, Brad has it right. Also Sonja's Violeta is a sex linked color as well just like the others.

That is a misprint, The males will be Blue and the hens will be Cameo.


OK, sense you want to talk Chromosome here we go and you thought you were lost before.

In the Avian biology sex chromosomes are the letters Z and W . The male is Z and the hen is W. The male would have two Z chromosomes ZZ and the female will have one Z and one W. The W only carries genetic information that makes up the female bird. The Z Chromosomes carry this sex linked recessive gene that makes the bird express the color. The gene for color must be on both chromosomes to be expressed in a male, and on the one chromosome for the hen to express the color.



This is why I don't care much for split birds, that is split to all different colors. You would have to keep GREAT records of the splits or you would never get what you wanted. I have found it less expensive in the long run to buy the colors, patterns etc, that I was looking for.

Oh well why didn't you just say so! This actually makes a lot more sense in these terms. It's basically the opposite of our gender chromosomes! Pretend males have two XX and females have XY instead of the other way, and call them different letters... that's all that's been done in terms of sex linked. Interesting!

So it IS safe to say that there is no 'split to' a sex linked color for females. Split to (sex linked color) will ALWAYS be male because the females only need 1. That puts me back on track!

I'm sure I'll be back in a few hours when I get to the last part of the chart which cover sex linked splits being bred to non-sex linked splits... but you've been a HUGE help!

EDIT: Ok! Second to last piece of information I need for this!
Can colors mutations carry colors?

I have a section of the chart where sex linked birds are crossed with colors and split colors... A purple male bred to a white female produces (by punnett square)... Males which have 1 Z with purple and 1 z with white... which if I have learned anything at all should mean a blue male carrying purple and white. HOWEVER. The chart also shows the females with a 'purple' Z but she should have white carried too... shouldn't she? But since it takes only 1 Z for females to display purple, she would have to LOOK purple and CARRY white (unless the white disappears).

I also have a section with blue splits... so if a non-sex-linked color gene carries regardless of gender chromosomes then could sex linked colors be carrying other colors?

Very simply put: Purple male x White female = Males are Blue split purple/white and females are purple split white?
Purple female x white male = Males are Blue split purple/white and females are Blue?

Purple male x Blue split white female = Males are Blue split White/Purple and females are.... purple split white again? Or is there a chance they are pure purple like a purplexblue pairing would produce?
Purple female x Blue split white male = 25% Males are blue split purple, 25% males are blue split purple/white.... 25% females are blue 25% females are blue split white?

And if you have excel and want to see what this beast is looking like so far...

EDITED

Updated the file to work on at home. All that's left are the blue split sex link and some of the regular sex link squares

Hope the rest is right.

Don't get too excited... it's just colors so far and I'm missing a lot of the sex linked stuff because I've just started in on that part today. If I can stomach it, I will try to do a patterns chart as well afterward.
