Bourke Genetics

[peterrebecca]

Hi

Could someone steer us in the right direction to allow us to understand genetics covering Rosa, Cream & Pink Bourke's please?

Thank you,

Peter & Rebecca.

I think Rosa is sex-linked, Cream is autosomal recessive & Pink is Rosa Cream??

Tiaris is correct. I have a chart of the breeding results from various pairings from an article I wrote about 15 years ago. I will find it and put it up later on

OR you could email to me and I would put it in the newsletter.

Sorry, meant bluebutterfly.

I first bred these mutations back in the mid-80's and Firetail555s' chart is correct.

I would like to add one pedantic note. I regularly see birds advertised at sales as "Split Pink", they are not. Depending on parentage males can be split for rosa, cream or both and hens for cream. If someone trys to sell you birds "Split Pink" then they don't understand what they are breeding and you won't know what your buying.

Just one of my personal bug bears.
