Help show cell division by manipulating large models. These models are designed to be printed on cardstock and/or laminated, and then to have magnetic tape or magnets attached to the back to allow them to stick to a whiteboard (or they may be printed on magnetic sheets). The models can be used on the whiteboard to walk through the steps of mitosis or meiosis.
The chromosomes are marked with capital and lower case letters to represent dominant and recessive alleles. These can be used to help students understand genotypes and setting up Punnett squares (a visual of what the letters really mean!).
There is a black&white set as well as a set with a small amount of coloring. There are 6 different chromosomes (labeled A/a, B/b, E/e, R/r, T/t, and X/Y).
