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.

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.
The main difference to remember is that natural selection is a nonrandom process while genetic drift is a random process.
1-2% the same difference between female humans and female chimpanzes
because there not the same and there different factors
Scientists think it is valuable to link genetic codes with medical histories for diagnosis and management of genetic disorders.
"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.

"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.

because u suck give me an answer and stop what you are doing

mutation means change in genetic structure..where as crossover means interchanging the genetic structure of two or more chromosomes..
