Deciphering the Language of Sex

Description: In this Howard Hughes Medical Institute program, Dr. David Page, professor of biology at the Massachusetts Institute of Technology, addresses the age-old question of why sex exists, and shows how sexual reproduction can have advantages over reproduction by cloning. Even from a purely biological perspective, gender is a complex subject. Dr. David Page reviews the biological basis for sex, emphasizing the role of the sex chromosomes—the X and the Y—in mammals.
