Abstract

This is a laboratory exercise designed to help students visualize the separation and randomization of alleles during gametogenesis by physically manipulating “chromosomes”. The chromosomes are represented by laminated paper strips each with an allele printed on it. After determining the potential gametes that a given genotype could produce, these are combined with those produced by their “spouse” to illustrate potential offspring. The exercise illustrates simple Mendelian inheritance, multiple alleles, and sex-linked transmission.
