Jack's father was an All$-$American in the $50M$ backstroke and qualified for the Olympic Team. Jack is a freshman in high school and does not think that he will need to train to become a member of the school's swim team. Jack keeps telling you that his father was a great swimmer, so he will also be a great swimmer. Based on your knowledge of gene$/$environment interaction, what is the most logical response?

Jack might have the genotype for swimming, but he will need to train to become a great swimmer.

He is correct; he will be a great swimming no matter what he does.

Jack has also inherited the genes for any athletic sport.

It is unlikely that Jack has the genotype for swimming.
