No dwarfies with diabetes so nothing valuable to add apart from:
although you could tell whether it is a spread or not, one assumes that as agouti is wild colour, there will be more of them in existence, so to be statistically valid, this would need to be taken into account.
though how one would identify the ratio of each colour I am not sure..
...mmm lovely research - I miss it in my recent job, I used to do a lot of research at one time too.
