Create your own karyotypes with clay in a kinesthetic genome activity. This tactile experience was created for visually impaired pupils, but can be used for all hands-on learners who are beginning to study chromosomes. The preparation directions are intended for teachers of the visually impaired, so adjust as needed for your classes. A reading activity is referenced and so is ddiscussion, but no reading is included, and the discussion information is quite limited.
Students explore chromosome karyotyping. For this chromosome karyotyping lesson plan, students use a chromosome kit to explore chromosome syndromes and disorders. They also produce a large model of a cell with chromosome to simulate cell division, the stages of cell division and the structures of the chromosomes.
Students comprehend that karyotyping is a process in which chromosomes are cut from an enlarged picture and arranged in decreasing order of size. The cells to be viewed are first chemically treated to increase the number of dividing white blood cells and then treated with colchicines to stop mitotic division during anaphase. Lastly, the cells are burst open, stained and fixed. The slide is examined for well spread chromosomes, photographed, and karyotyped.
Students study karyotyping, which is a process in which chromosomes are cut out from an enlarged picture and arranged in decreasing order of size. They use a template to arrange and glue chromosomes to data sheet, indicate sample code, chromosome abnormality and sex of sample.
Students use a karyotype to determine characteristics of the "baby" created in the lab activity. In this karyotyping lesson plan, students analyze the traits and characteristics that can be determined from a karyotype such as the sex of the baby and particular traits identified by letters on the karyotype. Students answer general questions about genetic diseases, traits on chromosomes and sex linked traits.
After teaching about the process of meiosis, use this presentation to inform your biology buffs of problems that can possibly occur. Gene mutation is mentioned as a review, and then different forms of chromosome mutation are explored: nondisjunction, deletion, inversion, duplication, and translocation. The use of a karyotype for identifying these problems is explained. It would be ideal to follow this presentation with a karyotype activity.
An explanatory introduction to genes opens the worksheet for young geneticists. Then, through diagrams and reading passages, mitosis is explained. This is just a general explanation, as the phases of mitosis are not mentioned. Pupils answer a few fill-in-the-blank questions and then use large objects and their arms to model mitosis. They repeat these activities for meiosis and for the fertilization process. Finally, they read about karyotypes and chromosomal abnormalities. The handout is informative, but the lab activities are not engaging.
What you will find in this collection of slides is a comprehensive introduction to genetics. It is technically three separate slide shows: the first on general genetics concepts, the second on rules of inheritance, and the third on genetic disorders. Geared toward high school biology, this may provide material for several lectures in your genetics unit.
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.
