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.
