Protoavis - thanks for your comments. The other thing that is not clear is if Tall Boy was breeding like a diploid or tetraploid. From what I understand, it have been fertile when crossed with both and so there is the complexity of not only the genetic diversity but also potentially from polyploidy.
Joe - feel free to contact me on the embryo rescue stuff. People have been extremely helpful to me in helping me get started many years ago when I first started with this and more recently when I dusted things off and started again recently. I would be glad to share what I know. I will post separately on the unreduced gametes.
