Hi all i have been slowly getting the hang of budgie genetics and i am wondering what exactly the term split mean?? I see it on the forums all the time written as / but what does it mean?

hey their jack

well split also seen as / refers to a male or female bird having either a sex linked gene or a recessive gene hidden in their make up

 

 

example

a blue opaline cock bird / albino

so here you can see the bird is visually only a blue opaline but hidden in his make up is the fact that he is from albino breeding

it could mean either peront was albino either mum or dad

or it could just mean his own father was split albino and he was passed on that sex linked genetic

 

or as in recessive birds the same thing apply's but the difference is with a recessive bird the genetic thats / lets say greywing

then both birds would need to be split for the actual visual appearance of a greywing in a clutch

where as with a sex linked / bird such as albino only the male can be split and doesnt need to be with a bird of that linkage to produce a vishial ,.... but in this case all the chicks that are visual will only ever be female

how as with a rec / bird young that are visual in nest could turn our either cocks or hens

 

 

i hope that makes scene

 

here is the list of sexlinked birds the one where only the male can be / too and females can only ever be visual

 

opaline

albino or lutino

lacewing

cinnamon

 

a list of rec variertys

 

fallow

rececive pied

clear wing

grey wing

dilute

crested

dark eyed clear

 

 

you also can get birds split for blue

but never split to green

 

then theirs the dominate colours that are only able to be produced if you have that variety these birds are not split

they are dominant in breeding so half the clutch is usually that variety

these are

dom pieds

spangles

dutch pids also called clearflighted pieds

yf birds but yf a bird can be split yf

so im told but i still understand that differently :rip:

 

 

their is most probably things ive missed but thats the general

so for example i have two birds with chicks at the moment and the father is a normal sky blue and the mum a DF white spangle. Does this mean that the chicks will be Sky blue/Spangle? or am i completely off?

The chicks will be skyblue spangles not split for spangle as you cannot have a bird split for spangle. It is a dominant gene.

i did try explain not well mind you

also a df spangle with a normal will give you all spangle chicks

as its a double dose of the dominant gene

as with

df dom pied to normal

df yf to normal

its very complex but quiet easy to grasp

okay, if I had a visual opaline father and a normal mother, all the males would either be visual opaline or split opaline, and females visual opaline or not opaline at all, is that correct?

not quite,(males must have two genes of a sex linked gene to be visual (one from each parent)

 

in the pair you brought up the male offspring will only be split for Opaline as they can't get another Opaline gene from the mother

 

the female offspring part is correct.
