All these numbers, figures, percentages etc are a nightmare to understand, blacky, especially if you're not a numbers person, like me.
I still can't my head around how a three quarter greyhound/collie isn't a two thirds greyhound 1 third collie!!
In a maths equation I get it, but if you put a pure greyhound to a pure collie x greyhound 1st cross, surely the resulting pups will be two thirds greyhound?!!
