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

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"One key to good fish breeding is providing fish with the right food. That means getting the right-sized food. As fish larvae grow, so does the optimum size of their food. That’s a problem for certain species bred in fisheries. Fish raised on live feed face a gap in their feed size as larvae: at a certain stage, the plankton they eat become too small for maximum growth. This “food size gap” can affect the quality and value of fish raised for consumption. But researchers from Japan appear to have one solution: “supersizing” plankton with beams of heavy ions. Researchers from the RIKEN Nishina Center for Accelerator-Based Science generated high-powered beams of carbon and argon ions in the hopes of producing size-boosting mutations in rotifers, a phylum of plankton commonly fed to fish larvae. The tremendous amounts of energy carried by these beams, a couple hundred thousand times the amount a human might receive during a routine CT scan, was enough to alter the DNA in rotifer cells..."
