Karyotyping provides genetic information,such as gender and chromosomal structure.Karyotyping is completed by photographing or using computer imaging to arrange chromosomes in pairs from largest to smallest.The karyotype can then be analyzed.Karyotyping does not determine lung maturity or if the baby is developing normally.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).
