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