Preimplantation Genetic Testing Involves

Preimplantation genetic testing involves:

A) testing a newborn infant for a genetic disorder immediately after birth.
B) testing a single cell of an early embryo for a genetic disorder before the embryo is considered for implantation into the mother's uterus.
C) testing multiple sperm from a man who is heterozygous for a serious genetic disorder and then using only sperm that have normal alleles for in vitro fertilizations.
D) removing cells from a fetus, testing them for a genetic disorder, and then allowing abnormal fetuses to be aborted.
E) testing primary oocytes (eggs) for genetic disorders before using them for in vitro fertilizations.
