Another daughter of Lucky Blanton was purchased after Mimi died, and her foals were, by contrast, a little bit disappointing. 

Partial explanation for that difference may be found in a couple of articles about the significance of mitochondrial DNA (The Heart of the matter, Parts 1 & 2) over at the Premier Pub site. -But!- I recently discovered that those assumptions are not entirely correct - the little bit of mitochondrial DNA contained in spermatazoa enters entirely into the egg, suggesting quite a different story than we are commonly told. (Sound familiar?) There is photographic evidence and some illuminating discussion offered by the clever people at Murdoch U - check it out! We can say empirically that the mare represents, on average, the greater part of the equation, but...

It would therefore seem likely that remarkably prepotent sires produce spermatazoa which mostly have larger midpieces than less prepotent sires - but, I digress.

The table with Mimi's Foals" is incomplete, but even so, helps to show the relationships between the various animals now on the place
 
 
 
 

below - Mimi with Paisana - I think this would have been in 1970.

Fact is that Mimi's daughter Libra was shown quite successfully Open per se, not just AQHA events. To judge from Equistat, a person would think that never happened.
