Addition of certain proteins, such as, bovine serum albumin enhances efficiency by protecting the DNA polymerase and by binding to PCR inhibitors.

The allelic frequency at equilibrium (qˆ) depends on the relative fitnesses (usually expressed as selection coefficients) of the two homozygotes:

Hitchhiking

An important consequence of linkage disequilibrium is hitchhiking. This happens when an allele at  one locus spreads by natural selection acting on a second locus that is in linkage disequilibrium with  the first.

Stabilized natural selection

Favor intermediate phenotype but eliminate lower and higher-grade phenotype

It introduced homogeneity in the population

Exp - clutch size of birds that lay too many or too few eggs per nest have lower fitness values than do those that lay an intermediate number of eggs
