hi guys,Studying genetics sure means inviting confusion.There is some one ,DEON SMITH, in South Africa who is believed to have done some good job on this subject.His emaill addy is gms@prieska.co.za He has prepared a genetic manual,costs 50 US$ incl pp.Any one interested in serious aviculture may kindly contact him.
I have a Blue male splite with albino and a female green split with lutino
Say she has 4 eggs what will the chicks colour be?
also I want to get some mutations happening. What are the best colours to breed with othere to get nice muticoloured ones?
there is a couple of things here to correct to arrive at the likely breeding results.
Firstly it is inaccurate to say the cock is blue split albino. Albino is not a true mutation but a combination of blue and lutino visually in the same bird. The two mutations cancel each other out and you end up with a white bird. So the cock must be a blue split lutino.
Secondly since lutino is a sex-linked gene the hen cannot be split to lutino - if she was carrying a lutino gene she would be yellow in colour due to the action of the sex-linked genes. It is likely therefore that she is just a green ringneck with no splits.
The result of breeding a blue split lutino cock with a green hen will be all males will be green in colour with half split blue and half split blue and lutino. Half the hens will be greensplit blue and half will be lutino split blue.
Therefore your 4 eggs should on average produce three green birds (2 cocks and one hen) and one yellow bird which must be a hen. All will be split for blue and one of the cocks will also be split for yellow. You won't get any blue birds since the hen needs to be split to blue (a recessive gene) for any blue babies to result.
However that is the theoretical result - in the real world they may be all green, all yellow or a mix but over many nests the ratios will move towards the theoretical result. For instance I had a pair of green ringnecks with the cock being split to lutino. It took about 16 babies before the first yellow appeared, by which time I should have had four, but by the time they had produced about 25 babies the ratio of yellow to green had got close to the 1 in 4 it should be.
