An Inexpensive Method to Simulate a Monohybrid Cross Using Wild-Type Zebrafish ("Danio rerio")

Monohybrid crosses are taught in biology labs across the country using peas and corn. Students studying monohybrid crosses using zebrafish ("Danio rerio") would encounter a new model organism, and those interested in human or veterinary medicine would have increased interest. To this end, our college has implemented a laboratory exercise at the introductory level using wild-type and non-pigmented zebrafish embryos to simulate a monohybrid cross. By using 1-phenyl-2-thiourea (PTU) to generate non-pigmented fish, the necessity of maintaining a separate albino line of fish is eliminated. Live embryos are preferable for generating student excitement; however, the option to use preserved embryos allows for re-use of fish over multiple years without relying on embryo production on a particular day.
