it’s not uncommon to see the children of people with great talent in some area to show such talent as well. in the world of music, for example, the children of talented people such as frank sinatra, John Lennon, Woody guthrie and nat King cole also show musical talent. can you think of examples of children ‘taking after’ their parents in other fields, such as sports? do you think this reflects genetics, or environmental influences, or a combination of both?

Assume that there is a gene which affects athletic ability. What sort of environmental factors do you think might interact with it to affect athletic performance? What would enhance it? What might impair it?
