Chapter 7, Problem 13TQ
Summary Introduction
Preimplantation genetic diagnosis (PGD) is used to detect genetic abnormalities. In this technique, one or more cells from the developing embryo (in the petri dish) are removed. This technique is usually performed after three days of fertilization. The cells that are removed from the embryo are evaluated for various genetic disorders. One or more embryos that are free from genetic disorders are implanted into the uterus of the mother. This technique is used to prevent genetic disorders in the offspring. The parents are having genetic diseases or carrying recessive alleles can use PGD.
