Umm PG, It's not Just Your Water....

So I have meant to post this for awhile, but you know how I said I didn't know what side sprigs were and didn't have them? Well I did know after I looked at the pics Claire posted so I took another look- my fav rooster from this year has them. They are just a swelling on each side at the back of his comb. I'll post pics when I finally get time, but how serious do you think this is?  I love his colour, he's huge with bright yellow shanks, but a bit aggressive. So he scores 3/5 points for my criteria. Opinions?

Clearly genetic, clearly more than one gene controlling.
A 1926 study (abstract at http://jhered.oxfordjournals.org/conten … 81.extract ) suggests that it is a result of two loci, with dominant alleles at both, so it should be easy to select against. . . if the author is correct. Haven't seen anything more recent than that, though.

Not necessarily. Breed him with ones you like the look of, and select the offspring that don't show the trait you dislike.
It's a tough call, with a limited genepool. Remember that the genes you "see" (and that you care about) are a tiny % of the genes that the individual carries, and while you want some genes to be homozygous (to produce that true-breeding phenotype), at many other loci you want diversity in the population, which means heterozygosity in the individuals. If you lose diversity at all loci, you'll eventually lose the breed.

Definately want to see pictures Susan. Compared to the sidesprigs on my other EOs the babies from your pair have very few side sprigs. I would not toss Sparkle on account of this finding by any means!

I am keeping and planning to breed some EOs with side sprigs. As ipf says, they are a very visual, but in the grand sceem of things small, trait. I will be trying to select against them as I go along. Lots of more important traits to worry about first though.

Oh and we should definitely add side sprigs to the list of topics for our Genetics Group! Or I suppose I can just read the article...

I totally want to know about side sprigs...and the difference between regular singles and the cluster in the clavell.
