Product Description
This assignment is designed to go with my interactive notebook, but it could be used as an activity or lab. After students have learned about alleles, chromosomes, and meiosis they receive the information sheet for this activity. On this sheet are the locations of the alleles on the bug's chromosomes and what those alleles code for (i.e. the first allele on the top codes for eye color, where red is dominant and blue recessive). On the same sheet are the phenotypes and genotypes of the parents. These traits are colored in on the activity sheet, and the genotypes colored in on the chromosomes (i.e. the male's phenotype is red and the genotype is heterozygous, so the chromosome gets colored red and blue). Once the phenotypes and genotypes are colored in students keep track of the alleles as they go through meiosis and recombine during fertilization. Students then use the information on the sheet to decode the offspring's phenotypes from the genotypes. I tell the students it's almost like a puzzle, trying to get the correct phenotypes at the end.
