Frizzles

[jwyles]

Frizzling is dominant. It is impossible to carry the gene without expressing it. Sadly, these chicks do not have the frizzle gene.

@Pyxis ive read something like this multiple times over. This is incorrect?

I'm going to go ahead and restate my original
post that I deleted bc I feel it's relevant. While frizzle is a dominant gene, a correctly bred frizzle is bred to a smooth therefore the frizzle parent and the smooth parent both possess the smooth gene and can therefore produce smooth chicks. Every bit of research I've done has backed this up. I deleted my original post but I do believe I was correct. I will recant if I find research that states otherwise. The frizzle gene IS dominant but that doesn't mean frizzle parents cannot produce smooth chicks so these chicks could come from a frizzle mom or dad.

A frizzle parent that has one copy of the frizzle gene can produce smooth chicks, because this parent also has one copy of the smooth gene. But that means that the smooth chicks did NOT get a copy of the frizzle gene. So they can't produce frizzled offspring, because they don't have the frizzle gene.

Your original statement was:

Maybe one parent was frizzle so your chicks will carry the gene and that's why the told you that. I know when people breed for frizzles they breed a smooth to a frizzle to avoid what I understand to be lethal genetic mutations. Therefore some of the chicks will show frizzling and some show smooth but they all carry the frizzle gene. So if yours are from a frizzle parent they might could make frizzle babies.

I was not saying that a frizzled bird cannot produce smooth chicks, I was refuting your statement that these two smooth chicks could produce frizzled offspring. In my original post on this thread I even stated that one of the parents of these chicks was possibly a frizzle A bird can't carry the frizzle gene. If they have a copy of the frizzled gene, they're frizzled.

Have you read about how dominant and recessive genes work? A dominant gene means the bird only needs to get one copy, or allele, of the gene for it to express. Frizzling is dominant. A bird gets one copy, and it's frizzled. It can only be smooth if it has NO copies of the frizzle allele. And if it has no copies, obviously it has no copies to pass onto its offspring, so it can't produce frizzled offspring.

Here is a punnett square, maybe this visual aid will help. In this square, we'll look at breeding one frizzled chicken that has one copy of the frizzle allele, denoted by the letter 'F', and one copy of the smooth allele, denoted by 'f' to a smooth chicken.

So the frizzled chicken is Ff, and the smooth is ff. The F means the chicken is frizzled, since frizzling is a dominant gene.

As you can see, half the offspring are Ff, or frizzled. Half are ff, or smooth. The ff offspring do not have copies of the dominant frizzle allele, F, so if you bred them together, there would be no way at all for them to produce an Ff chick. So, you cannot get frizzled chicks from smooth parents.

Hopefully this clears up the confusion

Yes I misinterpreted your response to my original post completely. Sorry about that.
