crossing black pekin hen with lavender frizzle roo

[itay]

Hi All,
my friend got eggs last year. some black pekins and lavender frizzle pekins.
I tried to get black frizzle by crossing black pekin hen with lavender frizzle roo.
yesterday , the first chick hatched and surprise - he got lavender ...

can someone will explain what went wrong ?

regards

The blacks were split for lavender. It's double recessive, so when bred with another color, it's there you just don't see it, but when bred with another lavender, you could get lavenders or more splits.

What a cute, sweet little baby, by the way!!

The black hen was split to lavender. When bred to a visual lavender, the results would be:

50% black split to lavender
50% visual lavender

The blacks split to lavender will look just like blacks that are not split, because lavender is a recessive gene and will remain hidden until bred to another split to lavender or a visual lavender. One gene is inherited from each parent, and a chick has to inherit two lavender genes (one from each parent) to be visual lavender. If it inherits only one lavender gene and one non-lavender gene, the chick will be split to lavender.

thanks a lot !
can you please explain what about the frizzle gen ? how it inherited ?

Frizzling does not show at hatch, but once the wing feathers begin growing in it will be obvious if present. It is an incompletely dominant gene.

Saying "double recessive" is inaccurate/redundant. For any recessive gene to express, two copies must be present.

My bad. That's how it was explained to me. So, back to the frizzle thing...can you explain "incomplete dominance"? Thanks!

Having one copy of the gene causes an intermediate affect between having zero copies and 2 copies. There is a strong dose effect. 1 copy frizzles the feathers; two copies excessively curls them, making them overly brittle. Blue is another incompletley dominant gene: 1 copy dilutes black feathers to blue; a second copy further dilutes them to splash.

Ok, I get it. Thank you! So, one more question on the frizzle thing (sorry OP, don't mean to hijack)...what about when you get a smooth feathered chick, I've heard people say they "carry the frizzle gene"...true or false? Like when I put my Ameraucana roo over frizzled pullets, if I get a smooth chick...???

False. Either they're frizzled or they're not - there's no such thing as a bird that is "split to frizzling".

I thought so. Thanks!
