My vote would be on yes, genetics would come into play here. Snakes will react differently to different husbandry styles. What is right for one snake might not be right for another snake of the same size, species or even clutch. While one snake would be perfectly content with its conditions, the other snake might end up being in a foul mood because the conditions don't meet its specific requirements.
Some BPs might never go to that 92 degree spot and would much prefer an 86 degree spot. While another snake would spend all its time on that 92 degree basking spot. Every animal is different and has its own quirks
