Unlike most population genetics labs, which involve simulations with beans or beads, this lab provides an opportunity to study a population of living organisms. Using Bar and wild-type Drosophila, students compare allele and genotype frequencies to Hardy-Weinberg expectations. Because the Bar mutation in Drosophila is sex-linked and incompletely dominant, students can determine the exact genotype of a fly from its phenotype. These data are evaluated to determine which (if any) of the five Hardy-Weinberg assumptions have been violated. This real-data approach allows students to appreciate the value of this null model and helps the instructor to discover and correct students' misunderstandings of the model.
This course is an introduction to the fundamental principles of psychology. It begins with a short overview of the discipline's development and principal methodologies. The subsequent units are arranged around broad areas of research, including emotion, development, memory, and psychopathology. Upon successful completion of this course, students will be able to: Identify the steps of the scientific method and explain how this method applies to psychological research methodology and statistical analyses; Demonstrate an understanding of the general history of the field; Explain the nature versus nurture argument and the current status of thinking regarding gene-environment interaction; Identify the basic components and mechanisms of the major biological systems often studied in psychology; Demonstrate an understanding of the basic findings within a variety of areas of psychology, including sensation and perception, memory and learning, development, social psychology, and psychopathology.
