Abstract
In a series of realistic examples, university students displayed support for interference with natural processes to prevent the births of defective children. The majority felt that an organism became a person before birth, yet that it was not murder to end such a life under specific circumstances. Women, older respondents, and students not currently enrolled in genetics classes showed more willingness to interfere more drastically in selected situations than men, younger respondents, and genetics students. However, the majority of the sample consistently opposed taking chances on producing children with genetic or birth defects.
