and 25% normal

then
50% normal split to recessive pied
50% recessive pied

So how would I put those together! ?!! O_o

(oh, and I used two different punnett squares to calculate the dominant and recessive's seperately...)

Come on everyone out there help us here!

I think it's added as follow:

25% + 50% + 25% = 100%
50% + 50% = 100%

thus as % out of 200% total sample gives:...

12.5% DF dom pied;
25% SF dom pied;
12.5% normal;
25% normal/recess pied;
25% recess pied...

Do correct me if I'm wrong!

PS-these figures are "statistically speaking" now with such %-ges... a large number of babies have to be produced before such typical %-ges are generated...so first few hatches (viewed / calculated in isolation) may distort the picture!

Here's a link to a website that calculates the genetic outcomes:
https://www.gencalc.com/gen/eng_genc.php?sp=0Budg

...how accuratey it is I'm not sure, but I think there's a problem with the "Yellow-face (YF)" answers?!

Good luck then!

your correct if you put 1 parent as a yellow face it tells you you'll get 100% yellow face when that is 100% Wrong :giggle: You do not get all yellow faces if one parent is yellow face and the other isn't.

it also shows they can be split to yellow face and many times I've been told a budgie can not be split to yellow face

so when I use it for a yellow face I just ignore the yellow face part all together I know I'll get some yellow faces I just basically do it for the main mutations and splits when known

Oh, sorry! When I put Dominant/Recessive I did NOT do a split. I did it as a Dominant Recessive Pied Female and a Dominant split to Recessive Pied Male.
Thanks for clearing up that link too, I didn't understand the shorthand, lol.
Does anyone know how you'd set this up in a Punnett square? I'd like to be able to do it myself instead of having to use an online calculator.
And I do know that the %'s are just that, possibilities. It's like humans with the 50% girl/boy thing, even if you have 5 kids they could all end up boys. ;P

your welcome :)
the percentages are out of 100 babies born to the pair If i recall correctly

not sure if this will help with your squares or not

https://www.****************/gen_dompied.html

then one for recessive pied
https://www.****************/gen_recpied.html

if you go here and click on details of any of the mutations it gives you the squares
https://www.****************/colorsguide.html

Maybe playing around with what they show you , and try to do it your self before scrolling down to see the out come may help

I've seen those links before, I actually just looked at the squares on that today. I understand 100% how to do a Punnett square with just one trait (like dominant pied)
I just don't understand how to combine the percentage outcomes for the different squares. :|
Because if you take two traits and take the percentages it adds up to 200% or more depending on how many traits you add together. I also don't know what ones to put together! Gah! (say like to figure out what % of babies will be visually dominant and recessive)

That's how you work it out, do each mutation separately then combine the result. Use the first set as a base so 50% of each group will also be recessive pied, making:
12.5% double factor dominant pied
12.5% double factor dominant pied & recessive pied combination
25% single factor dominant pied
25% single factor dominant pied recessive pied combination
12.5% normal
12.5% recessive pied
To add the splits half of each type will be split for recessive pied (except of course the ones that are already recessive pied). The total should always add up to 100%

Genetic calculators can be used but I never bother with them because it is easier to just work it out.

Ooook, I think I get it now, hopefully.
I like to use the Punnett's Squares too because technology can malfunction, and I'd rather rely on my own brain, lol.
