Genetics 1 Classroom Science Experiment Kit

Users become familiar with some human genetic traits and characteristics. They will be able to understand the differences they have inherited from parents. Kit contains PTC paper, wooden splints, red markers, white markers, and an instruction manual.

Genetics I includes three hands on activities. First students make genetics personal as they identify six of their own genetic traits, including the ability to taste the bitterness of PTC. Second, they model homologous chromosomes to demonstrate how reproduction results in the inheritance of genetic variation. Third, students use Punnett Squares in examples from humans, plants, and animals to apply concepts of statistics and probability in predicting the distribution and variation of expressed traits. Students use a randomized selection process and model the observed occurrence of allele frequency to compare to statistically predicted outcomes of crosses. Covers phenotypes, genotypes, monohybrid and dihybrid crosses, test crosses, dominance, incomplete dominance, codominance, and recessives. Includes worksheets, data sheets, and complete answer keys. Allow 45 minutes class time. Designed for 24 students working in groups of four.

• Hands-on genetics exploration: Three interactive activities help students identify personal traits, model chromosomes, and explore inheritance patterns.
• Apply probability and statistics: Students use Punnett squares and randomized simulations to compare predicted and observed allele frequencies across multiple organisms.
• Complete introductory genetics kit: Covers core concepts such as genotype vs. phenotype, dominance patterns, and mono‑ and dihybrid crosses; includes worksheets and answer keys for 24 students working in groups of four in a 45‑minute class period.
