Explanation: 

Detailed explanation-1: -Turner syndrome, a condition that affects only females, results when one of the X chromosomes (sex chromosomes) is missing or partially missing. Turner syndrome can cause a variety of medical and developmental problems, including short height, failure of the ovaries to develop and heart defects.

Detailed explanation-2: -Turner’s syndrome is a random genetic disorder that affects females. The main characteristics include short stature and infertility. Usually, a female has two X chromosomes. However, in females with Turner’s syndrome, one of these chromosomes is missing or abnormal.

Detailed explanation-3: -Turner syndrome results when one normal X chromosome is present in a female’s cells and the other sex chromosome is missing or structurally altered. The missing genetic material affects development before and after birth.

Detailed explanation-4: -XO syndrome typically occurs when a child receives an X chromosome from one parent, but no X or Y chromosome from the other. This condition is called monosomy X. The child is considered to be female because no Y chromosome is present.

Detailed explanation-5: -Mosaic Turner syndrome (TS) is a condition in which cells inside the same person have different chromosome packages. Mosaic TS can affect any cell in the body. Some cells have X chromosomes and some don’t. Every 3 out of every 10 girls with TS will have some form of Mosaic TS.
