Consider a locus with two alleles, A1 and A2. Mutation happens at this locus, but in a way such that A1 mutates to A2 with probability u and A2 mutates to A1 with probability v. If u = v (and neither of them = 0), the equilibrium frequency of the A1 is expected to be [Hint: set u and v to specific numbers that are equal to see what happens]:

The equilibrium frequency of the A1 (p = v/(u+v)) is expected to be equal to the equilibrium frequency of the A2 (q = 1 - p)

Explanation:

Available data:

The equilibrium frequency of the A1 is expected to be p = v/(u+v)

The equilibrium frequency of the A2 is expected to be q=1-p=1 - (v/(u+v))

For example, if V = U = 0.005, then

The equilibrium frequency of A1 = The equilibrium frequency of A2. The rate of mutation is equal for both alleles.

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.
