I wonder how much gene expression differs in clones of particular species raised in similar environments, I would expect the amount of difference between genetically identical individuals to differ by species, but I have no idea by how much, and how would humans rate on this measure.

They are approximately as varied as six foals from the same sire and dam would be normally.
In much the same way as you can spot similarities in two people who are even quite distantly related, you can often tell which animals are related just by looking. My neighbour had a pony that she got when she was quite little and who died something like ten years ago. All her daughters and grand-daughters look just like her.
The DNA is the code but the animal still goes through the growth process which involves a certain amount of randomness.
They all have the face stripe, but it varies in size. Look at the hind socks. Some have two, some have only one. That's more of a variation than the stripe width.
