What is the best explanation of PGD?

Answer 1

PGD is the abbreviated form for Preimplantation Genetic Diagnosis. This refers to procedures that are performed on embryos prior to implantation, sometimes even oocytes (female gametocytes or germ cells used in reproductions) prior to fertilizations. PGD is considered another way to prenatal diagnosis. Its main advantage is that it avoids selective pregnancy termination as the method makes it highly likely that the baby will be free of the disease under consideration. PGD thus is an adjunct to assisted reproductive technology, and requires in vitro fertilization (IVF) to obtain oocytes or embryos for evaluation.

Hope this helps with your work.

Answer 2

Preimplantation Genetic Diagnosis (PGD) is a technique used during in vitro fertilization to test embryos for genetic disorders before implantation. This helps identify embryos free of genetic diseases or chromosomal abnormalities for transfer, reducing the risk of passing on genetic conditions to offspring. It is particularly helpful for individuals with known genetic conditions or those at risk of passing on genetic disorders.
