a
(a): A human female with Turner’s syndrome has single sex chromosome $i.e., 44 + X0 (45)$. Such females are called sterile females with rudimentary ovaries. Other associated phenotypes of this condition are short stature, webbedneck, broad chest, lack of secondarysexual characteristics and sterility. Thus, any imbalance in the copies of the sex chromosomes may disrupt the genetic information necessary for normal sexual development.
