Hi everyone,
I was thinking today since Spangle is a dominant mutation (vs. Normal). Do we consider a Spangle budgie "split" for Normal?. So if bred with a normal budgie, would they get any normals?
I was just looking at one of my my chicks today, his markings look normal. His mother is a spangle and his father is a normal so I was just wondering :eek:

Thanks in advance :)

If you bred a single factor spangle with a normal budgie, there would be 50% spangles and 50% normal. The 50% spangles are heterozygous, meaning that one gene is spangle and one gene is normal. So, I guess yes, it would be spangle split for normal.

It amounts to the same thing but the term "split" is never used for the normal mutation. Any single factor dominant mutation has one unseen normal gene
