Ah, making another genetics thread not related to colors! So the other day I happened across someone that said that Secretariat ran with a double suspension transverse gallop rather than a regular single suspension transverse gallop. They also claimed it was part of why he was such a great race horse, that it allowed him to continue the 'sprint' speed for longer than other horses.
Now, before this I had never heard of horses using a double suspension transverse and honestly I couldn't find much more information on the topic but now I'm very curious! I was watching various race footage of Secretariat and awkwardly trying to pause it on every frame to spot the differences, I swear I saw something but who knows. Does anyone know if this is true or not? Or happen to know of any good footage of secretariat's gallop in slow motion or something so it could be seen?
This is the standard single suspension transverse gallop:
This is the double suspension transverse gallop:
Does anyone know of any other horses that did this as well? Is there some different genetics behind it? From what I read there were a few different theories, but over all not a lot of mention of it regarding horses at all. Most of the articles focused around greyhounds, whippets and cheetahs. The brief parts about horses; I believe one suggested that a difference to the muscular skeletal system? Or a gene mutation relating to Myostatin, though I may have been confused.
That did lead me to another mess of things though, particularly about myostatin mutations.
Some interesting information about it regarding dogs I will quote below, however I don't know if it applies the same to horses.
SO! Can anyone perhaps shed some more light on either of these two topics?

That same page more information but it was only available via purchase. :c
