Tom I agree with your sibling concept.

Subject: [iris] HYB: another terminology question
While we're at it, I'm interested in how people understand the term "sibling". I've seen it sometimes apparently restricted to two irises that came from the same pod of seed, or at least the product of the cross of two plants made by the same hybridizer in the same year. It seems to me that since the two parents are clones, any irises with the same parentage are siblings, even if the crosses that produced them were made many years or miles apart by different people. My own brother and sisters, for example, are no less my brother and sisters for having been gestated separately at different times. ;) Tom Waters Telperion Oasis ~ www.telp.com/irises Cuyamungue, New Mexico, USA (zone 6) ----------------------------------------From: "Tom Waters" <irises@telp.com>Sent: Friday, February 22, 2013 7:22 AMTo: iris@hort.netSubject: re: [iris] HYB: trying to learn some genetics terminology Yes, as Chuck has said F2 refers only to the result of crossing F1 individuals from the same initial cross. I don't believe there is any special terminology for the cross of two seedlings of related but not identical parentage.Tom Waters Telperion Oasis ~ www.telp.com/irises Cuyamungue, New Mexico, USA (zone 6) ----------------------------------------From: "Linda Mann" Sent: Thursday, February 21, 2013 7:16 PMTo: iris@hort.netSubject: [iris] HYB: trying to learn some genetics terminology F1 & subsequent generations.Online definition says F2 is > The progeny of self-pollinated F1 generation plantsBut I've also heard/read F2 used this way:> The F2 (second filial) generation consists of the offspring from allowing the F1 individuals to interbreed - the grandchildren of the parental generation.So what do I call the offspring of two related F1 seedlings that are not siblings, but are part of my non-line breeding program? i.e., crosses between half sibs, cousins, etc.I was assuming that any 2nd generation away from the parental one was an F2, but looks like that's not the way F2 is normally used.Linda Mann--------------------------------------------------------------------- To sign-off this list, send email to majordomo@hort.net with themessage text UNSUBSCRIBE IRIS--------------------------------------------------------------------- To sign-off this list, send email to majordomo@hort.net with themessage text UNSUBSCRIBE IRIS--------------------------------------------------------------------- To sign-off this list, send email to majordomo@hort.net with themessage text UNSUBSCRIBE IRIS
