## Principle or equation?

For the mathematics the title should rather be Hardy-Weinberg equation. Perhaps it is useful two have both articles? "Principle" for genetics, "equation" for mathematics. --Peter Schmitt 14:30, 13 August 2010 (UTC)

I have seen it referred to as "principle", "equilibrium", "law" and possibly even "rule" or "formula" but probably never as "equation". What would you intend to cover in the "equation" article if we were to go for disambiguation? Aren't the mathematical aspects (to be) covered by Binomial formula and related articles? --Daniel Mietchen 16:09, 13 August 2010 (UTC)
A search will show you that "equation" is quite common, too. Mathematically it is a probabilistic model frotm that an equation and an equilibrium can be deduced. While the mathematics is indeed very simple (binomial theorem), it is worth discussing the model. (It can be used both in probability theory and applications.) For genetics it is a "principle" and the -- as the current text shows -- is described quite differently as it would be for mathematics. --Peter Schmitt 18:24, 13 August 2010 (UTC)
I would think the model still fits in here, and I would thus try to draft both aspects in one article. If this does not work out, we can still split later on. We can put redirects any way you wish, or even move it to "equation" if you have a strong opinion about it. My point would be that geneticists don't search for it under "equation", but as long as they end up on the article about the genetic aspects if they search for "principle" and the others I mentioned above, the title does not matter that much. --Daniel Mietchen 19:54, 13 August 2010 (UTC)
