The ultimate act of intimacy serves to unite the male and female [[gamete]]s, the [[sperm]] and [[egg]], respectively. These gametes carry just one half of the [[gene]]tic material ([[chromosome]]s) from each parent, and when they combine the new [[embryo]] contains a full set of chromosomes, as well as its [[soul]]. The process of the gametes combining is called [[fertilization]], and takes place inside the woman's body, in the [[Fallopian tubes]] or [[uterus]]. The embryo then attaches itself to the uterine lining, and is nourished by the woman's body while it develops. This development takes roughly nine months.
