Ok... so... let's say your A/B only optimizes the colour and location of a single CTA button, and conversion rate is your fitness. 2 previous generations have top/blue and bottom/red. How does the next one look?
Each generation has like 10~20 candidate websites. The better the conversion rate, the more likely it is to get chosen as a parent.
With your example, let's say two parents with top/blue and bottom/red are chosen, then their offspring will either be top/red or bottom/blue because we make sure the same website isn't tested twice.
More generally each feature of the offspring will be randomly picked from the features of the two parents.
So two parents A/A/B and B/C/B can give the offspring A/C/B or B/A/B. There is also some random mutations that are possible with a low likelihood.
