what do splits mean?

[ConureLady]

When looking at conure mutations to purchase, I keep seeing "split" "double split" and "triple split"
What do these terms mean?

ConureLady this site explains it:MUTATION GREENCHEEKED CONURES I'm horrible at genetics so feel free to correct me but I think basically split is when they are carrying a mutation that isn't visible, so they have the potential to pass that genetic makeup along to their offspring.

Bpd is right. Split is just "bird talk" for heterozygous. Heterozygous means carrying a recessive trait. So, for example, a person can be heterozygous for albino. They are visually normal, but carry the gene for albinism. If they have a baby with another heterozygous (het) person, they have a one in four chance of having an albino baby. They also have a 1 in 2 chance of having a het baby (visually normal, carries the gene), and a 1 in 4 chance of having a homozygous normal baby (2 copies of the normal gene and no copies of the albino gene.)

In green cheek conures, if the birds are split for cinnamon, opaline (aka yellowside) or cinnamon-opaline (aka pineapple), then these birds *should* be males. Females cannot be split for those colors. Both colors are sex-linked. In humans, if a gene is sex-linked, then it means that the mother can pass that gene/mutation off to her male children, and the kids will be visual for that gene. The girls will also get that gene, but they will not be visual unless their father is also carrying that gene. In parrots, it's the complete opposite. If males carry that gene, all females that get that gene will be visuals and males split unless the hen is also a visual of that same mutation.

If the birds are split for turquoise, the birds could be either male or female. Turquoise is a par-blue (aka partially blue) mutation and is recessive, meaning either sex can be split for the gene, and you need two copies of that mutation to be visual.


Split means that the bird is split for at least one mutation.

Double split means the bird is split for two mutations

Triple split means split for three mutations.


A bird can't visually be a mutation and also split for it. If they carry that mutation, they are either visual or split. That is, a bird can't be cinnamon split for pineapple (cinnamon-opaline). If he's not a visual pineapple, then he's cinnamon split yellowside (opaline) - but he can throw pineapple offspring!


Genetics is pretty confusing when you first get into it, but once you understand the basics, it gets a bit simpler!

Basics such as recessive, sex-linked, dominant, co-dominant, etc.

Hi Do you know if there is a chart that shows dominant, recessive color genes? This genetic stuff is foreign to me. But trying to learn

It's an old thread - it has 10 years

Lol, I hear about "double" and "triple" spilts for the first time (I mean - I knew about its existence but I didn't know you call it so)
