Of course, fruit Students in Molly Renner's biology classes at City High School in Tucson, AZ created treehouses to document their fruit fly genetics experiments. Students will then apply their knowledge of monohybrid squares to complete two dihybrid squares. Then if you breed such a female with a white eyed male, some of the female offspring will receive an X chromosome from the mother containing the white mutation, as well as the white mutant allele on the X chromosome from the father. In fruit flies, the gene coordinates the body plan of the larva, which is manifested most clearly in the unusual shape of its cuticle when the gene is disrupted. Scientists use transgenic organisms, which contain DNA that scientists inserted in the organisms' genomes, to research many biological processes. Hemizygosity is also observed when one copy of a gene is deleted, or in the heterogametic sex when a gene is located on a sex chromosome.
