I guess you're referring to MY silly signature at the bottom of my posts. It wasn't meant to be offensive at all, I just thought it made sense for life in general.
Anyway, you would more likely get more "broken" bands from a pairing that had more incomplete banding than you otherwise would. But aberrancies like those are impossible to predict, and you can have offspring that are incomplete, and totally "normal" looking, and any combination thereof.....on the same token, you could also mate two complete banded siblings together from that same clutch, and have no broken ones, some broken ones, and/or any combination of the two as well.
But the "theoretical" odds percentage-wise would(should) be greater with two broken-banded pairings.
