Secular Pro-Life and a coalition of national pro-life groups have embarked on a unique project to highlight the humanity of the child in the womb and educate the public about prenatal development.
Baby Chris is just one cell big today—about 4/1000ths of an inch long—but will grow very quickly over the next nine months. Genetic traits from eye color to double-jointedness are already determined. Chromosomal sex (typically XX for females and XY for males) is also established at fertilization; however, the expression of Chris’s sexual traits may also be influenced by other genes and by exposure to hormones later in pregnancy.

Note that although Baby Chris has been alive for less than a day, he or she is considered two weeks old under the “LMP” (last menstrual period) method of pregnancy dating. The LMP system has some usefulness in a clinical context, where the exact date of conception can be hard to pinpoint, but for this project will we use the more accurate approach of measuring weeks from fertilization.
