c. a sterile female
d. a healthy female of slightly above-average height



Answer :

A patient has 47 chromosomes, including three X chromosomes will have the expected phenotype as d. a healthy female of slightly above-average height.

Triple X syndrome is marked by the presence of an extra chromosome in each female cell (47: 2A + XXX). The most common cause of this kind of error is the non-disjunction of sperm or ovum during meiosis. The affected female is often taller than average and has two more bar bodies in each cell.

The most prevalent physical characteristic is being taller than the average person. The majority of girls with triple X syndrome are capable of getting pregnant and have normal sexual development. When compared to their siblings, certain girls and women with triple X syndrome may have slightly lower IQ than those in the normal range. Others could struggle with behavioral issues and intellectual limitations.
