What colors will they produce?

[Strawberry74]

I have several sebastopol geese and am wondering what colors the following will likely make when paired up.

Gray saddleback gander with:
White goose
Gray saddleback goose
Gray goose
Blue splash goose
Buff goose

Buff/Lilac gander with:
White goose
Gray saddleback goose
Gray goose
Blue splash goose
Buff goose

Gray gander with:
White goose
Gray saddleback goose
Gray goose
Blue splash goose
Buff goose

Anyone have goose genetic experience to help give me an idea? Pic for fun!

Hi @Strawberry74

Grey SB / White - 50/50 Dilute Grey SB, Grey SB
Grey SB/Grey SB - Grey SB
Grey SB/ Grey - 50/50 Grey, Grey SB
Grey SB/ Blue Splash - 25/25/25/25 - Grey SB, Grey SB, Blue SB, Blue SB. There might be some dilution with these, as the spotting gene can throw some weird things in there just as an fyi.
Grey SB/ Buff - 50/50 - Grey (Split Buff/SB), Grey Saddleback

Lilac/White - 25/25/25/25 - Buff, Dilute (Grey), Dilute (Blue), Lilac
Lilac/Grey SB - 25/25/25/25 - Blue (Split SB, Buff), Buff, Grey (Split SB, Buff), Lilac.
Lilac/Grey - 25/25/25/25 - Blue (Split Buff), Grey (Split Buff), Lilac, Buff.
Lilac/Blue Splash - 25/25/12.5/12.5/12.5/12.5 - Blue, Lilac, Buff, Cream, Grey, Lavender.
Lilac/Buff - 50/50 - Lilac, Buff

Grey/White - 50/50 - Dilute Grey (Split SB), Grey.
Grey/Grey SB - 50/50 - Grey (Split SB) Males, Grey Females
Grey/Grey - 100% Grey
Grey/Blue Splash - 25/25/25/25 - Blue (Split SB), Grey (Split SB), Blue, Grey.
Grey/Buff - 50/50 - Grey (Split Buff) Males, Grey Females

Anything split will not show, but still carries it in their genetics.

Your Buff in on the right looks to be a SB so not sure if that messes with anything there

Also the back left lilac I think, might be sun-washed but I'd be interested to see their color if that is the buff/lilac you note.

Hope this helps. Also of note the Spotted Blue girl do you have an up close picture of her?

That's the only one where I'm a little apprehensive on genetics because sometimes they splash gene might just be an overly marked SB. Or an under marked SB etc.

If you need any help or have more detailed questions please let me know!

Holy moly, you are a wealth of genetic knowledge! Thank you for taking the time.

I will definitely get you better pictures. The way the sun is shining is not showing their true colors and four of the birds are not in that picture at all, one of them being my buff goose. The one that looks buff Saddleback on the right is actually a gray Saddleback Gander. He is my most gorgeous bird ever and was sold to me as a female based on the cross that was set up. He turned out to be a stunning Gander. The one that I called buff / lilac is kind of a question mark for me. I thought he was buff but then when mated with my white girl last year threw some blue colored babies. Someone I got some birds from this year in Pennsylvania mentioned that he looks to have some blue undertones and thought he might be carrying Lilac or something along those lines. I don't know how it all works so I am so appreciative of having found someone who can help direct me. Of course I realize not knowing full lineage definitely throws a curve ball. I'll try and get some better pics this evening and give some more background on who hatched from what possible pairings.

Yes - and knowing parentage is important in knowing how their babies will pop out.
And no problem it's just genetics

A big thing with crossing in white causes the dilutions, where you start seeing white around the beaks etc.

Some of my best birds are saddlebacks!

My goal this year is working on my greys, and moving to a white line personally.

If you ever need anything please don't hesitate to reach out!

@Pumperkinz I have been meaning to get back on this thread but been dealing with a family emergency. Finally finding some time.

These pictures are of Poppy, the buff/lilac gander in question. He was my first sebbie I successfully hatched! I tried to include several stages to show different feathers. One at a few months old, one after breeding season, one in all his curly glory. The picture next to the white goose is who he produced some blue colored babies with 2 seasons ago and he was my only gander then. There were 2 blues this recent spring but any one of 4 ganders are in that potential genetic pool. What are your thoughts on him? I make more posts for the others in question. Thanks!

Up next is Jack(pot), formerly Eleanor. Had a name change when HE revealed himself! He has the most beautiful and upright posture and a quiet disposition, definitely my biggest gander. I question if he fathered most of the babies this year even though all 4 ganders were a possibility. Four of the girls have his same large structure and upright stance. Two whites and two Blues or blue splash or whatever they are. This is the one that you questioned in the photo that might be a buff Saddleback but the light was making him look buff . But he's a Gray Saddleback.

So with Lilac he'd have some blue/grey trailing feathers and almost certainly have a brown "bean" on his tip of his beak btw. In your second picture he almost looks cream, which is really unique! It might be sun dilution too where the sun is basically diluting his color, but would make sense why he's producing blues.

This is my buff/lilac, normally they can get a black/brown bean and brown eyes. He has some darker brown feathering on his back as well. Can see my blue SB in the back left, and then the lavenders + greys are here.

My Grey SB boy.

Lavender Boy - Right
Grey Girl - Center
Buff/Lilac Boy - Left
Lavender Girl - Far Left
Blue SB - Left Center (clown face)


You can see the saddlebacks can throw dilution (white around the beak/patch under the chins.

Usually this is just incomplete dominance of the spotting gene (sp) and the Sd (sexlinked) gene so it can throw a lot of variables.

I know some people advertise all white birds that are color carriers btw. A full white bird is always going to be a color carrier as they have the traits to carry grey/blue/buff on their backside it just presents as pure white.



Your last grey guy would be a diluted grey SB. So he will throw a lot of variance in babies.

 

[Strawberry74]

Do you have a book? Where on Earth did you learn all this!?

So we're thinking my boy might actually be a cream? He does not have a brown bean but he does have brown eyes.

Your birds are very beautiful! How many do you have all together? And how long have you been raising sebbi's? Did you hatch them or buy them as goslings ? Your gray Saddleback Gander looks very similar to mine!

Do all your gray saddlebacks have blue eyes? The breeder I got my gray saddlebacks from was surprised they had blue eyes. All four of mine do.

Here are a couple of the girls that were hatched by a white Mama this year. I only let her sit on her eggs so I know they're all hers but it's a crap shoot who the dads are. Either gray, gray Saddleback or the cream boy.

Here are pictures of the blue girl I kept but the other blue girl looked identical. This is what I'd call Blue in my very limited knowledge so please advise. Her stance is very much like the gray Saddleback Gander which leads me to think he might have fathered most of the babies however not the full gray girl. Sounds like based on your explanation he could throw a lot of variance so he could be the dad.

I also had two white twin girls hatch this year out of the same bunch, all the same mom. They both definitely carry color because they have a few dark feathers on their back. Could the Saddleback Gander be there dad also?

Does his flight feathers have any darker color then the normal soft brown?

I raise the cream out because he's a softer brown but I don't see any dark dark feathers like the normal buffs.

I do not have a book, but maybe one day LOL.

I've been raising chickens for years, but this is my first year with sebbies! My original stock was goslings, and then I got some year old juvies in october.
