Thanks for the links!
I'd been unde...Hi Darren,<br />Thanks for the links!<br />I'd been under the impression that both species were 2n=20 but will have to see if I can figure out where I'd gotten that notion. Triploidy would certainly better fit the fertility behavior of the F1.<br />Thanks again, TomTomhttps://www.blogger.com/profile/05251272906203857137noreply@blogger.comtag:blogger.com,1999:blog-8292730528124689534.post-75566685409172010082014-04-18T18:07:09.602-07:002014-04-18T18:07:09.602-07:00Viola striata is tetraploid : http://www.amjbot.or...Viola striata is tetraploid : http://www.amjbot.org/content/98/12/1978.full<br />Viola walteri is diploid : http://www.io-net.com/violet/violet3/walteri(e).htmDarren Abbey, PhDhttps://www.blogger.com/profile/08452703848133489576noreply@blogger.comtag:blogger.com,1999:blog-8292730528124689534.post-77882993909605171082014-04-17T14:35:11.672-07:002014-04-17T14:35:11.672-07:00That sounds like the F1 is triploid.

In this model, there would be very few viable F2s and they would likely be aneuploid.<br /><br />I tried looking up the chromosome counts of Viola striata and V. walteri, but I didn't find anything conclusive.Darren Abbey, PhDhttps://www.blogger.com/profile/08452703848133489576noreply@blogger.com
