To solve this problem, we need to understand the characteristics of Turner’s syndrome. Let's analyze each option:$\newline \bullet$Option 1: Has 45 chromosomes with XO.$\newline$ - Turner’s syndrome is a chromosomal disorder where a female is born with only one X chromosome.$\newline$ - This results in a total of 45 chromosomes instead of the usual 46.$\newline$ - Therefore, this option is correct.$\newline \bullet$Option 2: Has one additional X chromosome.$\newline$ - This describes Klinefelter syndrome, not Turner’s syndrome.$\newline$ - In Turner’s syndrome, there is a missing X chromosome, not an additional one.$\newline$ - Therefore, this option is incorrect.$\newline \bullet$Option 3: Exhibits male characters.$\newline$ - Turner’s syndrome affects females, and they do not exhibit male characteristics.$\newline$ - Therefore, this option is incorrect.$\newline \bullet$Option 4: Is able to produce children with a normal husband.$\newline$ - Most individuals with Turner’s syndrome are infertile due to underdeveloped ovaries.$\newline$ - Therefore, this option is incorrect.$\newline$Based on the analysis, the correct option is Option 1: Has 45 chromosomes with XO.
