Stripes in Festival Fanfare

I added this rose last year and have really come to like it as a garden rose. I notice that there is no listed offspring of this rose other than sports. It set several OP hips and I was able to get several seeds from it.

Deos anyone know if the seeds from this rose germinate?

Since this is a sport of a non-striped rose, is the striping a genetic or a viral thing(I thought that it had been mentioned that striping may be the result of a virus). If its a genetic thing, could this striping be passed on to offspring?
