Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.

By the end of this section, you will be able to do the following:

Explain the relationship between genotypes and phenotypes in dominant and recessive gene systems
Develop a Punnett square to calculate the expected proportions of genotypes and phenotypes in a monohybrid cross
Explain the purpose and methods of a test cross
Identify non-Mendelian inheritance patterns such as incomplete dominance, codominance, recessive lethals, multiple alleles, and sex linkage

By the end of this section, you will be able to do the following:

Explain Mendel’s law of segregation and independent assortment in terms of genetics and the events of meiosis
Use the forked-line method and the probability rules to calculate the probability of genotypes and phenotypes from multiple gene crosses
Explain the effect of linkage and recombination on gamete genotypes
Explain the phenotypic outcomes of epistatic effects between genes

By the end of this section, you will be able to do the following:

Describe the scientific reasons for the success of Mendel’s experimental work
Describe the expected outcomes of monohybrid crosses involving dominant and recessive alleles
Apply the sum and product rules to calculate probabilities

Since the discovery of the structure of the DNA double helix in 1953 by Watson and Crick, the information on detailed molecular structures of DNA and RNA, namely, the foundation of genetic material, has expanded rapidly. This discovery is the beginning of the "Big Bang" of molecular biology and biotechnology. In this seminar, students discuss, from a historical perspective and current developments, the importance of pursuing the detailed structural basis of genetic materials.

General Biology is intended to leave the student with an integrated view of the living world including the nature of sciences, evolution of biological organization, composition and organization of living substances, metabolism, control, reproduction, heredity and ecological relationships. This class meets the A.A. degree lab science requirement in the State of Washington.Login: guest_oclPassword: ocl

This course describes biological changes that happen on a very large scale, across entire populations of organisms and over the course of millions of years, in the form of evolution and ecology. Upon successful completion of this course, students will be able to: Use their understanding of Mendelian genetics and patterns of inheritance to predict genotypes and phenotypes of offspring or work backwards to identify the genotypes and phenotypes of a parental generation; Distinguish between inheritance patterns that involve autosomal vs. sex-linked traits and identify the respective consequences of each type of inheritance; Identify what distinguishes DarwinĺÎĺĺÎĺs theory of evolution from other arguments that attempt to explain diversity across species and/or many generations; Identify which of many types of natural selection is acting on a particular population/species; Identify which of many types of sexual selection is acting on a particular population/species; Identify the factors that alter the frequencies of alleles in populations over time and describe the effects of these factors on populations; Recognize, read, and create phylogenies and cladograms, using them to explain evolutionary relationships; Determine the ecological interactions affecting a particular community and identify the effects of specific relationships (e.g. symbiosis, competition) on species within that community; Distinguish between world biomes in terms of their climate, nutrient cycles, energy flow, and inhabitants; Use their knowledge of nutrient cycles and energy flow to estimate the effect that changes in physical or biological factors would have on a particular ecosystem.
