"He" has a penis with two holes in the end. When he urinates, the urine comes out of both holes. "He" is 14 and has not started puberty yet.
Answers:
Most males have one X chromosome and one Y chromosome; that's an XY genotype. Normal females have two X chromosomes; XX genotype. Some babies are born with only one X chromosome; that's an XO genotype. XO's are all female; this disorder is known as Turner's Syndrome. These women are often of short stature, have short wide necks, wide chests, short chubby arms and lack normal sexual development {absent breasts, no menstruation, little or no pubic hair, and are sterile}. This syndrome is present in 1 of every 2,500 live female births. A male without a Y chromosome? No way! Yes, some males are born with an extra Y chromosome { XYY genotype; there are usually no problems with these men }. Others are born with an extra X chromosome { XXY genotype, known as Klinefelter's Syndrome; these males are usually sterile, have some breast development, and wide hips }.
