I haven’t heard anyone seriously bring up Lamarkian theory of inheritance of acquired characteristics in a while.
(were you serious? I am not always quick to pick up a joke).
Your children would acquire genes based on those of their mother and their father. Some of those genes would express as dominant and recessive, some with some interaction… and of course there would be some mutations (some good, some not good, and most not of any interest at all). Your life choices and experiences can affect the ways those genes would express. Epigenetics is still not an old science, and we continue to learn how it all works. Of course, your life choices and experiences can affect a lot, even without genetics. For example, if you have more of the kind of muscle fiber that responds to anaerobic training, and someone else has more of the fiber that responds to aerobic training each of you has a greater capacity to excel in those areas (though you each also start with undifferentiated muscle tissue that you can train to one area). So nature and nurture are always intertwined.
btw…. evolution is rather slow…. and requires a population rather than an individual.
