Name Two Methods Used in Genetic Prenatal Diagnostic Testing in Humans

Question

Name two methods used in genetic prenatal diagnostic testing in humans.
A)chorionic villus sampling and cellular mitotic analysis
B)whole genome sequencing and PCR
C)amniocentesis and DSCR
D)amniocentesis and NIPGD
E)amniocentesis and fetal uterine physiology compatibility test

Accepted Answer

The two methods used in genetic prenatal diagnostic testing in humans are amniocentesis and Non-Invasive Prenatal Genetic Diagnosis (NIPGD). Amniocentesis involves the removal of a small amount of amniotic fluid containing fetal cells for genetic analysis. NIPGD, on the other hand, involves the analysis of free-floating fetal DNA in the mother's blood. It is less invasive compared to amniocentesis and has a lower risk of complications. Therefore, D is the best choice.
