Investigate sex-linked traits and patterns of inheritance in Nasonia vitripennis, a parasitic wasp that does not sting or bite.
- Introduce your students to Nasonia, an excellent organism for studying genetics
- Results can be obtained in less than 2 weeks with just one cross
- Nasonia has many different genetic varieties available
In a series of predictive exercises, including crossing Nasonia with different eye colors, students will decide what to look for in the F1 generation in order to determine whether a gene is dominant, recessive, or sex-linked.
When the F1 generation emerges, students will be able to note that there are red-eyed males and dark-eyed females, suggesting that eye color is indeed a sex-linked trait.
