A couple has been counseled for genetic anomalies. They ask you, "What is karyotyping?" Your best response is
a. "Karyotyping will reveal if the baby's lungs are mature."
b. "Karyotyping will reveal if your baby will develop normally."
c. "Karyotyping will provide information about the gender of the baby and the
number and structure of the chromosomes."
d. "Karyotyping will detect any physical deformities the baby has."
C
Feedback
A The L/S ratio, not karyotyping, reveals lung maturity.
B Although karyotyping can detect genetic anomalies, the range of normal is
nondescriptive.
C 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.
D 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).
