Question

Quizplus · Accepted Answer

The presence of three X chromosomes and a total of 47 chromosomes indicates that the woman has Triple X Syndrome (also known as 47,XXX). This condition typically results in a normal female phenotype, with no significant physical or developmental abnormalities. However, in some cases, individuals with Triple X syndrome may experience developmental delays or learning difficulties. Facial hair, enlarged genital structures, excessive emotional instability, and sterility are not typical features of Triple X syndrome.
