The Biology of Sex Chromosomes

Location: Signature
Address: 1501 Preble Avenue, Suite 200 Pittsburgh, PA 15233

About the Study

The science of male and female is rapidly changing. The idea of two sexes is somewhat simplistic and biologists now think there is a larger spectrum than just binary male and female. Individuals can be a compilation of Xs and Ys, such as XXY, XYY, or even XO. According to experts, around 1.7% to 4% of the population is born with intersex traits—individuals born with any of several sex characteristics including chromosome patterns, or reproductive or sexual anatomy that doesn’t fit the boxes of “female” or “male.”

Signature researchers are seeking participants to be involved in a study to explore the biology of sex chromosomes and how they determine gender. Participants in the study do not need to identify as intersex but must be over the age of 18 and never have been pregnant.
