Product Details

Large simulated chromosome smears make this kit one of a kind. Your students can now realistically cut out chromosomes and use key characteristics to match them into pairs. The concept of chromosome pairing (homologous pairs) will have new meaning as students prepare human karyotypes. The six chromosome sets provided illustrate a normal male, a normal female, a male with Down syndrome, a female with Down syndrome, a person with Klinefelter syndrome, and a person with Turner syndrome. The karyotyping procedures used by a geneticist are employed during the completion of the karyotypes in this kit. The ease of use, the clarity of the chromosome pairs and the inexpensive nature of this pencil/paper simulation makes it a real money saver. You'll use the chromosome simulation masters for years to come!

Performance Expectations

MS-LS3-1. Develop and use a model to describe why structural changes to genes (mutations) located on chromosomes may affect proteins and may result in harmful, beneficial, or neutral effects to the structure and function of the organism.
MS-LS3-2. Develop and use a model to describe why asexual reproduction results in offspring with identical genetic information and sexual reproduction results in offspring with genetic variation.
HS-LS3-1. Ask questions to clarify relationships about the role of DNA and chromosomes in coding the instructions for characteristic traits passed from parents to offspring.
HS-LS3-2. Make and defend a claim based on evidence that inheritable genetic variations may result from (1) new genetic combinations through meiosis, (2) viable errors occurring during replication, and/or (3) mutations caused by environmental factors.
