Sizzle Genetics - Can Someone Confirm :D

[FlyingGarlic]

I want to understand how to go about breeding a Sizzle Chicken. It is my understanding that the Sizzle has the characteristics of both the Silkie and the Frizzle chicken. I have tried to do some research online, including posts on this forum, and have not really found what I was looking for.

One website/post said:

· Frizzle x Smooth gives you 50% frizzle and 50% smooth This suggests incomplete dominance.

· Silkie x Smooth gives you 100% smooth This outcome suggests that it is a recessive trait.

Are they the same genes for smooth? Or is it just one allele? ​

So, if it is two separate genes then I have randomly assigned:

· The F allele for Frizzled feathers Frizzle chicken Ff, Non Frizzle ff, and Frazzle FF

· The f allele for non-frizzled feathers

And…

· The s allele for Silkie “feathering” Silkie ss, Smooth but, carries Silkie trait Ss, Smooth SS

· The S allele for smooth feathers

If the above alleles are correct and you wanted to breed a Sizzle and only had a Frizzle Rooster and Silkie hens:


Frizzle Rooster: FfSS

Silkie Hens: ffss


The phenotype (what you see) would be:

50% Frizzle and 50% Smooth



After running a dihybrid cross in an online calculator, the Frizzle and smooth would carry the gene for Silkie.


So if you were to breed the best Frizzle offspring from this pairing to a Smooth coated sibling then you would get:

Frizzle Rooster: FfSs

Silkie Hen: ffss


This would result in the following outcome:


· FfSs 25% of any chick being Frizzle carrying Silkie

· Ffss 25% chance of any chick being born Sizzle

· Ffss 25% chance of any chick being born smooth

· ffss 25% chance of any chick being born Silkie


For those of you who have experience breeding Sizzles, would this be correct?

Thank you,

I don't have experience, but genetically that is correct. I assume when you say 'Sizzle' you are talking about a bird expressing both Frizzle and Silkie feathering and NOT a 'Sizzle breed' which is a project breed that is basically a silkie body type bird with frizzled feathers.

Yes! I mean that the bird will display the characteristics of both ...

Thank you so much!
