Genetics affects many aspects of our lives. Identify three ways genetics affects your life or the life of a family member or friend. The effects can be regularly encountered or can be one time only or occasional.

Define the terms allele, chromosome, and gene, and explain how they relate to one another. Develop an analogy between these terms and the process of using a street map to locate a new apartment to live in next year (i.e., consider which term is analogous to a street, which to a type of building, and which to an apartment floor plan).

Define the terms genotype and phenotype, and relate them to one another.
