Part III-PGD? Suzanne and David decided to have children. They wanted to ensure that their children would not inherit Suzanne's disease, and are now considering whether to utilize a process known as pre-implantation genetic diagnosis (PGD). This process involves in vitro fertilization (IVF) and genetic testing of the resulting embryos for the APP mutation. Only embryos without the mutated APP gene would be implanted. The others would be discarded. Should Suzanne and David have PGD? Questions 1. What is in vitro fertilization? Does it carry risk? How is the procedure accomplished?

Genetic Recombination
Recombination is crucial to this process because it allows genes to be reassorted into diverse combinations. Genetic recombination is the process of combining genetic components from two different origins into a single unit. In prokaryotes, genetic recombination takes place by the unilateral transfer of deoxyribonucleic acid. It includes transduction, transformation, and conjugation. The genetic exchange occurring between homologous deoxyribonucleic acid sequences (DNA) from two different sources is termed general recombination. For this to happen, an identical sequence of the two recombining molecules is required. The process of genetic exchange which occurs in eukaryotes during sexual reproduction such as meiosis is an example of this type of genetic recombination.
Microbial Genetics
Genes are the functional units of heredity. They transfer characteristic information from parents to the offspring.

![Part III-PGD?
Suzanne and David decided to have children. They wanted to ensure that their children would not inherit
Suzanne's disease, and are now considering whether to utilize a process known as pre-implantation genetic
diagnosis (PGD). This process involves in vitro fertilization (IVF) and genetic testing of the resulting embryos
for the APP mutation. Only embryos without the mutated APP gene would be implanted. The others would
be discarded.
Should Suzanne and David have PGD?
Questions
1. What is in vitro fertilization? Does it carry risk? How is the procedure accomplished?
2. Who has access to IVF/PGD? What would obstacles to access be? Are these procedures typically covered
by insurance?
3. Do women egg donors undergoing IVF incur any risk? If yes, what might those risks be? What about the
risks for the sperm donor? Why do people decide to continue with IVF knowing about potential risks?
4. What are the arguments/ethical issues surrounding this couple's use of IVF/PGD to determine the
inheritance of this particular disease gene? If screening for disease genes is okay, is it also okay to
screen for the sex of the child? If not, how would you describe the differences between the two types of
screening? What about other traits, such as physical attributes and intelligence? Please explain.
