Biology and Society The incidence of births of children with Down syndrome increases markedly after maternal age of 35. Do you think that mothers over the age of 35 should seek fetal testing? Strongly Disagree © 2018 Pearson Education, Inc. A B C D E Strongly Agree

Biology and Society Genetic tests are now available to screen women with a high genetic risk of developing breast cancer. Some women in this situation have opted for a radical mastectomy before the appearance of a tumor. As a doctor, if your patient tests positive for a breast cancer gene, would you consider advising her to have a mastectomy to remove both breasts before a tumor appears? Strongly Disagree © 2018 Pearson Education, Inc. A B C D E Strongly Agree

Biology and Society One of the first human cell lines to survive indefinitely was that derived from a cancer patient who died in 1951. The He. La line, named for Henrietta Lacks, continues today in laboratories throughout the world and is even available for high school classrooms for studying karyotyping. In 1951, people didn’t fully realize the potential applications of unique cells or DNA. Do you think that a patient should retain all rights to their cells or DNA during medical procedures? Strongly Disagree © 2018 Pearson Education, Inc. A B C D E Strongly Agree
