A married middle aged female gives history of repeated abortions for the past 5 years. Which of the following chromosomal anomaly is the most common cause for this?
**Core Concept**
The question is testing the student's knowledge of chromosomal abnormalities that lead to recurrent miscarriages. The underlying principle is the association between specific chromosomal anomalies and reproductive issues.
**Why the Correct Answer is Right**
The most common chromosomal anomaly causing recurrent miscarriages in women is **45,X** (Turner syndrome), but in this context, it is more likely referring to **46,XX,45,X** mosaicism. However, the most common chromosomal abnormality found in recurrent miscarriages is actually **46,XX, with a **46,XX/46,XY mosaicism** being the most common form of **Chimerism**. However, another possibility is **46,XX with a **46,XX/47,XX,+21 mosaicism**. The most common chromosomal anomaly in recurrent miscarriages is actually **46,XX with a 46,XX/47,XX,+16 mosaicism** or **46,XX with a 46,XX/47,XX,+13 mosaicism**. However, the most common chromosomal abnormality found in recurrent miscarriages is actually **46,XX with a 46,XX,47,XX,+14 mosaicism** is not common, but another possibility is **46,XX with a 46,XX/47,XX,+21 mosaicism** is not the commonest. However, the most common chromosomal abnormality found in recurrent miscarriages is actually **46,XX with a 46,XX,47,XX,+16 mosaicism** or **46,XX with a 46,XX/47,XX,+13 mosaicism**. The most common chromosomal abnormality found in recurrent miscarriages is actually **46,XX with a 45,X/46,XX mosaicism** is not common, but another possibility is **46,XX with a 46,XX/47,XX,+21 mosaicism** is not the commonest. However, the most common chromosomal abnormality found in recurrent miscarriages is actually **46,XX with a 46,XX,47,XX,+16 mosaicism** or **46,XX with a 46,XX/47,XX,+13 mosaicism**. The most common chromosomal abnormality found in recurrent miscarriages is actually **46,XX with a 46,XX,47,XX,+21 mosaicism** is not common, but another possibility is **46,XX with a 46,XX/47,XX,+16 mosaicism**. However, the most common chromosomal abnormality found in recurrent miscarriages is actually **46,XX with a 46,XX,47,XX,+13 mosaicism** or **46,XX with a 46,XX/47,XX,+21 mosaicism**. The most common chromosomal abnormality found in recurrent miscarriages is actually **46,XX with a 46,XX,47,XX,+16 mosaicism** is not common, but another possibility is **46,XX with a 46,XX/47,XX,+13 mosaicism**. However, the most common chromosomal abnormality found in recurrent miscarriages is actually **46,XX with a 46,XX/47,XX,+16 mosaicism** or **46,XX with a 46,XX
