[Gmod-help] Re: [Gmod-schema] Unique constraint in natural diversity module

[Bob MacCallum]

Wasn't it just that if you are measuring two phenotypes, say leaf size and
fruit weight, then you'd use two nd_experiments (each linked to the same
stock) because you need two nd_protocols to describe the two assays?

We have no objections to relaxing the constraint though - I'm sure there are
situations where 1 to many is needed.
