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.

By the end of this section, you will be able to:Explain the relationship between genotypes and phenotypes in dominant and recessive gene systemsDevelop a Punnett square to calculate the expected proportions of genotypes and phenotypes in a monohybrid crossExplain the purpose and methods of a test crossIdentify non-Mendelian inheritance patterns such as incomplete dominance, codominance, recessive lethals, multiple alleles, and sex linkage

In this problem-based learning module, students will investigate the importance of genetic diversity will be explored by examining several case studies revealing consequences that can occur in individuals within a limited gene pool and how a variety of genes can lead to the survival of a species. Students will be able to create and interpret information from pedigree charts.

A video that makes the unspoken assumptions that we use in pedigree analysis explicit through a skit of two students solving a challenging pedigree question over videoconference. The students discuss certain pedigree assumptions which are often not mentioned in other pedigree teaching materials, even though they can be important to solving complex problems. The students recognize that not all assumptions are always applicable and sometimes we need to reconsider which assumptions to use.Includes two videos: a version without subtitles and a version with subtitles
