He's beautiful!

He is a boy, yes? I am looking at the blue cere. How old is he now? Will you get cinnamon babies out of him? So beautiful!

Girl! The mom wasn't cinnamon but the dad was split for cinnamon! So from birth I knew she'd be a girl!

About 2 months old I think. I'll get 100% split for cinnamon male babies from her (if her partner isn't cinnamon or split for cinnamon)

@Zoohtasim , can you explain the genetics of that? You give very easy-to-understand explanations!

I think I already have in my mutations thread! There's a post about cinnamon mutations in there! But for a quick description -

The cinnamon mutation is a sex linked (carried only in the x chromosome) recessive (meaning all the x chromosomes of the bird have to be carrying the cinnamon gene for it to be expressed phenotypically) mutation. That means female budgies are either cinnamon or not cinnamon (as they have only one x chromosome) and cannot be carriers. Males however, can be cinnamon, not cinnamon or carriers. So, daruchini's granma, Alikkhi Pakhi, is a cinnamon female. She had chicks with a normal (not carrier) male. So, ALL of her male children were split for cinnamon. And one of those males (carrier) had chicks with a NORMAL female (not cinnamon). Now, 50% of the male children would've been carrier and 50% normal. 50% of the females would be normal and 50% of the females would be CINNAMON (getting one x chromosome from dad carrying the cinnamon gene is enough for her to express the mutation) So it's clear that if I got any cinnamon from this clutch, it'll be female. And daruchini is cinnamon! So ofc she's female! And if I'd breed her, the male chicks would be split for cinnamon (just like in the case of alikkhi pakhi and that normal male having chicks)

I have a better description in the mutations thread! This is just practical application of genetics which is really important in my opinion. I was wondering how to get a cinnamon male and I thought maybe I could pair up one of my females with a male and see (maybe she would be a carrier is what I thought) then 2 seconds later I remembered that she CAN'T be a carrier I know so much abt this gene in pen and paper but irl? It's easy to forget

Would you perhaps get a cinnamon male if you cross her with a split male?

Now, 50% of the male children would've been carrier and 50% normal. 50% of the females would be normal and 50% of the females would be CINNAMON

50% chance per bird, not for the entire batch of eggs. You will probably get 50 50 split with a very large amount of offspring but you won’t necessarily with a smaller amount, so better to think of it as the chance per bird

Would you perhaps get a cinnamon male if you cross her with a split male?

I I have done it correctly! You would get either cinnamon or split males and cinnamon or none females. I have attached a punnet square, CI is cinnamon and ci is non-cinnamon. I don’t know what symbol is for it normally

 

[AntiqueB]

Ooh! When will you try that???

Yes! But all the females and split males I have are related Maybe I can breed 2 more generations of of them to really separate out their genes and breed them to get a cinnamon male. OR I could buy one. But for the past 5 years, I LITERALLY CAN'T FIND ANY CINNAMON MALES they either look like they are gonna die or I just cant find them. Dhur
