"Preimplantation Genetic Diagnosis, also known as genetic testing,is a procedure performed on embryos to determine the possibility of the baby developing inherited genetic disorders and diseases."
There are multiple areas at which one could study about preimplantation genetic diagnosis. The National Centre for Biotechnology Information being one of them.

Embryo biopsy is the process of removing a cell from an embryo, usually at three days of development. Preimplantation genetic diagnosis (PGD) is the act of performing genetic testing on the cell that has been removed from the embryo before that embryo is transferred to the uterus. In other words, embryo biopsy is necessary in order to perform PGD. Shannon DeWall, MS, CGC Genetic Counselor and Program Coordinator Genesis Genetics Institute
PGD stands for Preimplantation Genetic Diagnosis. It is a reproductive technology used in conjunction with in vitro fertilization (IVF) to screen embryos for specific genetic conditions before implantation in the uterus. This process helps couples at risk of passing on genetic disorders to have healthier children.
"procedures that are performed on embryos prior to implantation, sometimes even on oocytes prior to fertilization. PGD is considered another way to prenatal diagnosis. When used to screen for a specific genetic disease, 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"
Genetic counseling is important in SMA, since prenatal and preimplantation genetic diagnoses offer the parents the possibility to prevent the disease.
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.

Pre-implantation genetic diagnosis (PGD) is a technique which involves the genetic testing of embryos created through IVF for deleterious, heritable genetic conditions which are known to be present in the family of those seeking treatment and from which the embryos are known to be at risk.
PGD for Gender Selection also referred to as PGS or Preimplantation Gender Selection is a technique that enables couples with a particular inherited condition in their family to avoid passing it on to their children. It is also used with the purpose of gender selection for couples who have had more children of the same sex to want to have a family balance and choose the gender of the baby. Sex selection is legal in most of the world, yet it has limitations. Preimplantation genetic diagnosis (PGD) screening is allowed in most countries to determine a genetic condition that the embryo might inherit. Yet specifically PGS (Gender Selection) is not allowed with the specific purpose of determining the sex of the child - in countries including China, India, UK, Australia, Korea, Canada, Belgium, Spain, France, Germany, Hong Kong and Italy. However, it is allowed in select countries such as former soviet countries and in Latin American countries.
Genetic counseling can influence the gene pool by providing individuals and families with information about genetic disorders and inheritance patterns, which may inform their reproductive choices. By assessing the risk of passing on genetic conditions, couples may opt for prenatal testing, preimplantation genetic diagnosis, or even choose not to have children. This can lead to a reduction in the prevalence of certain genetic disorders within the population over time. Additionally, genetic counseling promotes awareness of genetic diversity and the importance of carrier screening, potentially impacting mate selection and genetic mixing in future generations.
Morquio syndrome, a genetic disorder, is inherited in an autosomal recessive manner, meaning a child must receive two mutated copies of the gene (one from each parent) to be affected. To reduce the risk of transferring the condition, prospective parents can undergo genetic counseling and testing, especially if there is a family history of the syndrome. If both parents are carriers, they may consider options such as in vitro fertilization with preimplantation genetic diagnosis to select embryos without the disorder.
