A Punnett square can be used to detect Down syndrome.

Question

Quizplus · Accepted Answer

A Punnett square is a tool used in genetics to predict the probability of offspring inheriting certain traits from their parents. Down syndrome, however, is not a single gene disorder and is not caused by a simple inheritance pattern that can be predicted by a Punnett square. It is a chromosomal disorder caused by an extra (partial or full) copy of chromosome 21. Detection of Down syndrome involves specialized genetic testing, not a Punnett square analysis.
