The Autosomal Dominant mutation
The Autosomal Incomplete Dominant mutation
When you only want to know the outcome just scroll down!
A Dominant mutation , is dominant against the wildcolour, which means that a dominant mutation paired to a wildcolour (or another mutation) can give directly some dominant mutation youngsters, the other normall coloured are not split as in this mutation no splits exist . It's the colour or not!
This mutation can arise without inbreeding, it's pure luck, it occure the same as all other types of mutations, but here is the single factor visible, in the other mutations they are split. Therefore this mutation is also the easiest for saving the mutation, to do without inbreeding. because 50% of the young will be the colour.
The differences of Autosomal Dominant mutation and the Incomplete Dominant mutation, are both Autosomal Dominant mutations but from the Autosomal Dominant mutation is no visual difference between a single factor ( = SF) and a double factor (= DF), but from the Autosomal Incomplete Dominant mutation there is a difference between SF and DF birds. The SF have 1 time the colour in it, DF is having 2 times the colour in it, a DF is therefore more coloured.
A few examples of these mutations are in lories:
Autosomal Dominant mutation ; the greygreen mutation (also called wrong olive) here a double factor looks the same as a single factor. (slaty, or sometimes pied,... are also Auto. Dominant mutation but are not in lories yet).
Incomplete Dominant mutation ; pied( some breeders would call it a Autosomal recessive mutation, as there is sometimes no or almost no difference between a SF and a normal) , misty (or jade and true olive as they call it in Australia), dark, aqua (probably named wrong, as aqua is normally an Autosomal recessive mutation)... also violet, spangle, edged, euwing,... are incomplete dominant mutations but doesn't exist yet in lories.
Here some examples of pairing up a Autosomal Dominant mutation or the Incomplete Dominant mutation.
The pairing inherits the same but remember that a SF look the same in a Autosomal Dominant mutation as the DF and the Incomplete Dominant mutation the SF less coloured then a DF.
Also here I try to explain the outcome with the punnett square.
As it's also a Autosomal mutation (mutation on the gene located on an Autosome chromosome), so not on the Sex chromosome, it doesn't matter if the male or female is the mutation.
As the SF has only 1 (single) mutation gene I also write normal for the other gene.
The double factor (DF) = 2 x SF
And yes the genetics will say it's wrong, but I wright it like I would understand..
SF Misty X SF Misty = ( SF normal X SF normal)
So you get
25% Misty Misty = DF Misty
50% Misty normal = SF Misty
25% normal = normal, pure wildcolour
I'm not going to write every outcome with the punnett square but below you can see all the possible outcomes when you breed with the autosomal dominant mutation.
normal x SF gives:
• 50% normal = pure wildcolour
• 50% SF
SF x SF gives:
• 25% normal = pure wildcolour
• 50% SF
• 25% DF
SF x DF gives:
• 50% SF
• 50% DF
DF x DF gives:
• 100% DF
DF x normal gives:
• 100% SF
