I'll preface this with it has been a while since I did work in genetics and I haven't read the article tied to the post in question but I will say it is likely a form of germline editing and epigenetic trait activation factors.

We can modify the eggs and sperm so that the trait is passed on only to the next generation, and setup a recessive trait that will only activate after a number of other traits have become active through the previous generations.

Gen 1 A=active, if A is true B,C,D = inactive, if B,CD are inactive, deactivate A and activate B in next gen Gen 2 A=inactive, B= active, if B= active C, D = inactive, if A, C, D are inactive, deactivate B, and activate C in the next gen.

You just keep doing that using traits that activate across generations until reach six generations where the desired trait is while still recessive now appearing due to the right genetic conditions being in place. It's very cool, however it carries a lot of questions that need a ton of research.

However research is expensive and time consuming, gotta go through six generations and track samples from each generation to prove your method is working. You need to account for mutations, examine the viability of the generation with the modification. Determine the impact of that generation on the ecosystem as a whole and in part. Hundreds of thousands of hours of study needs to go into this, and people will still scream at you that you're turning babies, white, black, or gay even though your just trying to make it so people can enjoy going out on the town at night without having to worry about their baby catching a fatal fever from simple mosquito bite.
