Data Table 1 contains a series of genotypes and phenotypes for a variety of hypothetical genetic traits. The genotype and phenotype for "Parent 1" are provided in Data Table 1. For each of the traits in Data Table 1, determine your phenotype and possible genotype(s).
Note: If you have a dominant phenotype, you may have either a recessive allele and a dominant allele, such as “Aa,” or two dominant alleles, such as “AA.” If your phenotype is recessive, your genotype is always homozygous recessive such as “aa.”
Use the mirror to determine if you have a dimpled chin.
Record either "Dimpled Chin" or "No Dimples" under "Phenotype & Genotype(s) from Parent 2" in the "Dimpled Chin" row.
If you have a dimpled chin, record "Dd" and "DD" under "Phenotype & Genotype(s) from Parent 2" in the "Dimpled Chin" row to represent the 2 possible genotypes for your observed dominant phenotype.
If you do not have a dimpled chin, record "dd" under "Phenotype & Genotype(s) from Parent 2" in the "Dimpled Chin" row to represent the 1 possible genotype for your observed recessive phenotype.
Repeat steps 1 - 4 for the remaining 9 traits in Data Table 1.
