This column is the new total, and is calculated by p2(1+s) + 2pq(1+s) + q2 Calculates the proportion of homozygous recessive individuals. Note that there is no selective advantage to this genotype. Calculates the proportion of the heterozygous individuals after selection. Calculates the proportion of the the homozygous dominant individuals after selection.
