Featured in PASCO’s College Biology Instructor Guide
College Instructor edition with 26 experiments covering introductory and general biology topics.
Use the common fruit fly, Drosophila melanogaster, to create and statistically analyze genetic crosses.
This lab allows students to use the common fruit fly, Drosophila melanogaster, to perform genetic (monohybrid, dihybrid, and sex-linked) crosses. This lab provides an excellent opportunity to work with and manipulate live organisms in a laboratory setting. During this investigation, students explore:
Students gain experience conducting the following procedures:
Culture vial label or labeling tape
Index cards - 2
Instant Drosophila culturing medium - 1 to 2 g
Mutant flies (autosomal monohybrid F1 cross) - 1 vial per class
Mutant flies (autosomal recessive dihybrid F1 cross) - 1 vial per class
Mutant flies (sex-linked F1 cross) - 1 vial per class
Small, thin, camel hair paint brush
Wild type flies - 3 vials per class
This experiment may require software and an interface for data collection.
