Abstract
Our introductory biology students use the parasitoid wasp, Nasonia vitripennis, to investigate independent assortment, epistasis, linkage and crossing over in eye color of F1 and F2 offspring. The advantages of Nasonia vitripennis over other commercially available model organisms are: 1) these insects can be sexed in the pupal stage; 2) development can be arrested by refrigeration (induced diapause); 3) induced diapause can also be useful if you wish to maintain your own stock; 4) recessive alleles are easily “visible” in these haplodiploid insects through the haploid male and 5) the life cycle is approximately 14 days.
