8) After reading the following paragraph, answer the question(s) below.
Brittany's family includes several individuals with a genetic disorder that affects primarily males. Her husband Tony has no history of the disease to pass on to their children. They've decided that their best chance to have a healthy family is to have only daughters. Through a new type of assisted reproductive technology, it's possible to separate sperm that will produce sons from those that will produce daughters. Brittany's eggs will be fertilized by in vitro fertilization (IVF) with sperm that can produce only daughters. The developing female embryos can be implanted into her uterus to complete development normally.
