Answer:
A
Explanation:
The correct answer would be that <u>de novo incidences of DiGeorge syndrome occur as a result of errors during maternal or paternal meiosis, creating a new variant.</u>
<em>Since the syndrome has high penetrance, it is highly unlikely that any of the parents would be misidentified or that one of the parents has the variant without symptoms. It is also highly improbable that both parents would be carriers because if they do, they will definitely show some symptoms.</em>
Hence, the most likely explanation is that the variant emerges as a result of errors during maternal or paternal meiosis leading to the formation of a gamete with the variant.
