Explanation:

1. Analyze the karyotype: Count autosomes (pairs 1-22) and sex chromosomes.
2. Autosomes: Pairs 1-21 are complete; pair 22 has one chromosome.
3. Sex chromosomes: Only one X chromosome is present.
4. Match to conditions: Turner's Syndrome is defined by a single X chromosome (45,X karyotype), with missing or partial second sex chromosome and no autosomal trisomy, which matches this karyotype.

Turner's Syndrome
