Question

Quizplus · Accepted Answer

Karyotyping provides genetic information such as gender and chromosomal structure.The lecithin/sphingomyelin (L/S)ratio,not karyotyping,reveals lung maturity.Although karyotyping can detect genetic anomalies,the range of normal is nondescriptive,and not all such anomalies display obvious physical deformities.The term deformities is a nondescriptive word,and physical anomalies may be present that are not detected by genetic studies (e.g.,cardiac malformations).
