I updated this to create a free download of the activity from my Teachers Pay Teachers store. Please check it out and leave feedback!

This is a nice introduction activity for middle school or high school when you begin the discussion of heredity.   Name: _____________________________                       Genes Activity Procedure: Determine your phenotype (outward trait) and then the genotype (alleles present for trait) for each trait and record in the given column.  If you are unsure if you are homozygous (AA) or heterozygous (Aa) for a trait, consider yourself heterozygous. Transfer your genotypes to the chromosomes by writing one allele in each box on the corresponding chromosome. Initial your chromosomes. Cut out the chromosomes and fold them o
