Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.

This exercise is intended to help students understand the role of transcription factors and enhancers in differentiation in general and with sex determination specifically. Students will put events in order for male and female sex determination. Note that students do not need to know anything about sex determination to complete the exercise (but they learn it as they play), but they should have been exposed to the concepts of enhancers and transcription factors.
It should be noted that the cards saying "It's a boy" and "It's a girl" were selected to emphasize that this pathway is relevant for anatomical sex determination as opposed to gender.
From something as small and complex as a chromosome to something as seemingly simple as the weather, sex determination systems vary significantly across the animal kingdom. Biologist and teacher Aaron Reedy shows us the amazing differences between species when it comes to determination of gender.
