Students describe the differences between incomplete dominance and codominant alleles, and between multiple alleles and polygenic inheritance. They describe how internal and external environments affect gene expression. They then interpret testcrosses and pedigrees charts.
This PowerPoint jumps right into the details of unusual traits and how they are coded.  The epistasis patterns in Labradors are used as a main example, and many instances of polygenic inheritance malfunctions are explained. All of this should grab your students' attention!
Students explore the mode of inheritance of chromosomes. Given a scenario, students use the Human Genome sheet to determine inherited chromosomes. They illustrate the difference between genotype and phenotype. Students develop a model using chromosomes.
Upon dissecting a young tree branch and inspecting the cambium layer, apical buds, and other physical features, green thumbs also grasp the meanings of the genetic terms genotype and phenotype. Not only are genetics and plant physiology covered in this tremendous resource, it also adheres to the Common Core requirements for literacy in science.
In this genetics worksheet, learners answer 42 questions about meiosis and sexual life cycles, Mendel's Laws of Inheritance, chromosomes and protein synthesis.
In this animal behavior instructional activity, students complete a 50 multiple choice question review quiz on how animals respond to certain stimuli.
Twelfth graders investigate the inheritance of traits through several hands-on activities that illustrate the transmission of genetic characteristics. Students study advanced topics including multiple alleles, polygenic traits, pleiotropy and epistasis.
Students explore genetics through various hands-on activities. In this biology lesson, students predict the probability of offspring genotypes and phenotypes using the Punnett Square. They explain the causes of genetic abnormalities.
Students study genetic traits using popsicle sticks as chromosomes. In this biology lesson, students explain how traits are inherited from parents. They differentiate dominant and recessive genes.
In this biology worksheet, 9th graders determine whether it is possible for two alleles to produce four genotypes. Then they state how many alleles there are for blood type. Students also determine which blood type is inherited by incomplete dominance.
Students examine polygenic traits, how they work and how parents determine the trait of a child.  in this polygenic traits lesson plan students divide into groups and complete a lab.
