These are a set of 10 genetics review cards that include GENOTYPE, PHENOTYPE, HOMOZYGOUS DOMINANT, HOMOZYGOUS RECESSIVE, AND HETEROZYGOUS as the main vocab words. They are formatted for Avery business cards product number 8871 but you can print on card stock and cut out just as easily. I feed the paper in once, flip it, then feed it again. I use them for students that may be struggling and need to work during a study hall or after school. They can take the pack with them, self check, then bring them back to me!
