Equation

Equation

1. A making equal; equal division; equality; equilibrium. Again the golden day resumed its right, And ruled in just equation with the night. (Rowe)

2. (Science: mathematics) An expression of the condition of equality between two algebraic quantities or sets of quantities, the sign = being placed between them; as, a binomial equation; a quadratic equation; an algebraic equation; a transcendental equation; an exponential equation; a logarithmic equation; a differential equation, etc.

3. (Science: astronomy) a quantity to be applied in computing the mean place or other element of a celestial body; that is, any one of the several quantities to be added to, or taken from, its position as calculated on the hypothesis of a mean uniform motion, in order to find its true position as resulting from its actual and unequal motion.

4. Equation box, or Equational box, a system of differential gearing used in spinning machines for regulating the twist of the yarn. It resembles gearing used in equation clocks for showing apparent time.

5. (Science: astronomy) equation of the center, the difference between the place of a planet as supposed to move uniformly in a circle, and its place as moving in an ellipse.

Origin: L. Aequatio an equalizing: cf. F. Equation equation. See Equate.

mutation-selection balance

I'm having problems figuring out the logic behind two formulas related to the Hardy-Weinberg equation. Here are two relevant excerpts from my textbook, Medical Gentics by Jorde, Carey and Bamshad: Consider, for example, a dominant disease that results in death before ...

Re: FLU/time to FLU/mg/min

... the reference compound was prepared for the standard curve in basically the same volume - that is 50 ml. So, then I can understand that to the equation i am putting the right things M = mol/ V (in L). Grams = moles X MWt

FLU/time to FLU/mg/min

... on y-axis. Then I would say my my slope = RFU / uM And then if if I put each RFU values that I want to convert them into Concentration using this equation uM = RFU / slope Is it correct. Also, I am not quite sure how to convert uM values into mmole?

Re: Re:

This is turning out to be an interesting thread (I love mathematics). So, it seems as if F1 somehow defies the Hardy Weinberg equation by having genotype frequencies that one would not expect from the allele frequencies. This effect is evened back out when the F1 interbreed to produce ...

Re:

... is approximately 0.35 and the square root of 0.32 is approximately 0.57 Not only are these values different, they do not add up to 1. With another equation, it can be shown that the values 0.4 and 0.6 are indeed correct. Remember, the P generation dominant allele frequencies are 0.6 and 0.2. (0.6 ...
