Hi there.
Whe i was in high school we did genetic experiments, we cross polinated red beans with white ones and the results were 100% predictable the next generations all the beans were red, the next after that was 75% red 25% white.
Also, i took the high heel example because i have a bit of a high heel fetish, and when i asked some girls i knew if they had problems wearing high heels, those who wore them regularily said no, and often stated that their mothers didn't either, while the ones that didn't said that they tried but couldn't and i asked if their moms did and they didn't
Not scientific but, such experiments would take decades to run to term with little chance of getting to the end, since everybody has a life of their own and have "more important" things to do.
