What Technique Can Be Used to Detect Genetic Defects in Early

Question

What technique can be used to detect genetic defects in early stage embryos,prior to implantation?
A) genetic screening
B) chorionic villus sampling
C) PGD
D) amniocentesis
E) micromanipulation

Accepted Answer

Preimplantation genetic diagnosis (PGD) is a technique commonly used to detect genetic defects in early stage embryos prior to implantation. PGD involves removing one or two cells from the embryo and testing these cells for genetic abnormalities before transferring the embryo to the uterus. PGD is useful for couples who know that they carry certain genetic mutations and want to avoid passing them on to their children.
