The genetics of marshmallow monsters

An example of one of the randomly determined marshmallow creatures.

The seventh grade science team finished the heredity and genetics unit last month by having the children determine characteristics and traits for an imaginary marshmallow critter. The students tossed coins to determine varying genotype and phenotype for several characteristics, including number of body parts, number of eyes, color and number of spikes as well as curly and/or straight tails. All the species were to have four legs of either orange or blue and most were able to stand. The kids really enjoyed their edible critters and their comments and understanding relating to varying traits within a given species was off the charts!
