Question

Name the genetic disorder in a human female having 44 + XO karyotype. Mention the diagnostic features of the disorder. Explain the cause of such chromosomal disorder.

Answer 1

Turner’s syndrome is a genetic condition caused by the presence of a single X chromosome (monosomy XO). Affected individuals are females who exhibit immaturity of reproductive organs, resulting in sterility. They typically have underdeveloped ovaries, a webbed neck, a broad chest, and breasts that are not fully developed. Additionally, individuals with Turner’s syndrome often have below-average intelligence and may show short stature along with shortened fourth metacarpal and metatarsal bones.
