1) Ullrich-Turner syndrome
2) gonadal dysgenesis
3) 45,X
4) All of the above

Answer 1

Turner syndrome is known by several names including Ullrich-Turner syndrome, gonadal dysgenesis, and 45,X; thus, the correct answer is 'All of the above'. It is a condition where a female is born with only one X chromosome, leading to developmental and reproductive issues.

Step-by-step explanation:

Turner syndrome (TS) is also known as 1) Ullrich-Turner syndrome, 2) gonadal dysgenesis, and 3) 45,X. So, the correct answer to the question is 4) All of the above.

Turner syndrome occurs when a female is born with only one copy of the X chromosome, a condition known as monosomy. Unlike individuals with the typical XX or XY chromosome pairs, those with Turner syndrome have an XO genotype, which leads to various developmental, hearing, and cardiac impairments, as well as short stature and sterility due to undeveloped sexual organs. This chromosomal anomaly affects only females, as the presence of a Y chromosome would make the individual male.
