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.
Pupils explore genetics. They discuss how chromosomes and/or genes are regulated during the life of an organism. In a lab setting, students compare and contrast the genomic regulation of prokaryotic and eukaryotic cells using manipulatives. They complete a fertilization lab and discuss the synthesis of DNA.
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.
