ss

What this part means

the assigned value 1.

Its job in the formula

s is part of the quantity the equation computes from the expression on the right.

Where the article explains it

Set s = 1 , the theoretical maximum in which every affected embryo is detected and never implanted: for q = 0.01 , this gives qn+1q_{n+1} = qnq_n/(1+qnq_n) ≈\approx 0.009901 , a reduction of under one-tenth of one percent of the allele’s frequency in a single generation, even at total, universal, perfectly effective screening.
