Population Genetics: Genetic Drift, Natural Selection, and Mutation
Students discover genetics as it relates to the population. In this biology lesson, students examine mitosis and mutations. They discuss the shift in genetics due to natural selection and genetic drift.
Students use a mathematical simulation of genetic drift to answer questions about the factors that influence this evolutionary process. They run a series of simulations varying allele frequency and population size and then analyze their data and propose a model to explain their results. A second set of simulations is performed with natural selection added to the simulation.
Speciation and Genetic Drift Worksheet
Fifteen terms pertaining to speciation, extinction, and gene flow are to be matched to their definitions. This simple, easy-to-read worksheet can be used as a pop quiz for your biology learners when studying natural selection principles and genetic drift.
Evolution of Populations
In this evolution worksheet, students look at the role genes play in the transferring of traits to generations. Students review gene pools, natural selection, and genetic drift. This worksheet has 5 fill in the blank and 15 multiple choice questions.
Inheritance of Genetic Disorders
Learners explore inheritance patterns of diseases. For this genetic lesson, students explain how recessive genes may cause human disorders. They identify and research five genetic disorders and present their findings to the class.
Evolution of Populations
In this evolution worksheet, students review the genetic aspect of evolution such as gene pools, specific traits, and genetic mutations. This worksheet has 15 multiple choice and 5 fill in the blank questions.
Mechanisms of Evolution
What does appearance have to do with survival in nature? Allow your future biologists a chance to learn about natural selection through games, flashcards, discussions, and an interesting writing prompt about squirrel colors in the Grand Canyon. Also included are several ways to differentiate, possible extensions, and school-home connections.
AP: Chapter 23: The Evolution of Populations
How and why do populations change over time? AP biology aces explore this question by completing this assignment. They write the answers to 21 questions regarding population genetics, stability, genetic drift, polymorphism, and selection.
Natural Selection - The Mechanism of Evolution
A sufficient slide show on natural selection is available to use with your biology class. It introduces viewers to foundations of this mechanism of evolutionary change. Notes are provided to support your lecture on genetic variation and the three types of selection: directional, stabilizing, and disruptive. Helpful graphs and photos enhance understanding of the concept of natural selection.
Island Biogeography and Evolution
Students use this activity as a logic problem that is based on real organisms and real data. The problem is to develop phylogenies for seven related populations of lizards living on the Canary Islands. Three phylogenetic charts are constructed, each using different forms of data, geography, geology, morphology, and molecular genetics.
Students study genetics by role playing. In this genetics lesson plan students play the role of a doctor and interpret genetic test results.
The Expression of Genetic Information
Students examine genetic information that is within a cell. In this genetics lesson students view videos on DNA and genes then explain a cells function.
Island Biogeography and Evolution: Solving a Phylogenetic Puzzle With Molecular Genetics
Students engage in solving a logic problem based on real organisms and real data. They develop phylogenies for seven related populations of lizards living on the Canary Islands.
Evolution and Theory
Students discuss Darwin's theory of evolution. In this biology lesson, students investigate what influenced Darwin's thinking as it relates to Evolution. They discuss pros and cons of Natural Selection.
Natural Selection Foldable
Students examine and identify examples of species that developed as a result of immigration, genetic drift, and adaptive radiation. They conduct Internet research and define key vocabulary terms, and use their species example on their Natural Selection Foldable.
Digital Analysis of Variation in Rodent Jaw Length
Learners study digital images to acquire data and evaluate the jaw of a rodent. For this science lesson students perform statistical analysis.
Evolution of Populations
In this evolution worksheet, students review the ideas expressed by Darwin, gene pools, genetic variation, single-gene and polygenic traits, and natural selection. This worksheet has 9 fill in the blank, 5 multiple choice, and 3 matching questions.
Students view a video that reviews Mendelian genetics. They discuss the Hardy-Weinberg Law and use Popsicle sticks to simulate genetic variations and ratios in offspring.
Hardy-Weinberg Equilibrium According to Hoyle: OR, Population Genetics or Platypapyrus foursuitii
Students use this exercise to help achieve a working knowledge of the Hardy-Weinberg Equilibrium without recourse to algebra. After participating in this activity, students gain a feeling for the significance of the Hardy-Weinberg Equilibrium without using algebra.
Students explain the basics of evolution by natural selection. They calculate allele frequencies as they relate to inheritance. They explain the Hardy-Weinberg Law and how evolution takes place when this law is not in place.
