Ward's® Case of the Red Eyed Female Lab Activity

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.

Ordering information: Activity contents include: 1 vial of Sarcophaga pupae (the host organism for Nasonia), 1 vial of Wild-type male Nasonia pupae, 1 vial of Scarlet-eyed female Nasonia pupae, a teacher's guide, and a student copymaster.

This item contains a coupon for live or perishable materials. You will need to provide a date that the live or perishable components will arrive.

Delivery information: The kit will ship separately from the live component. Kits do not contain perishable components and generally ship via UPS ground. Perishable components will ship via overnight or second day delivery.
