Chapter 26, Problem 2QSDC
Summary Introduction
To review:
Whether the genes for early development or the genes for cell differentiation will be identified first, in case of identifying the genes that are required for the early development of chicken.
Introduction:
Drosophila belongs to the family Drosophilidae and is a type of fly. Its common name is vinegar fly or common fruit fly. The Drosophila melanogaster is a species that has extensive use in physiology, life history evolution, genetics, and microbial pathogenesis.

D. lab
As a volunteer in a genetics lab, Professor Uhura tasked you with testing the biparental mitochondria inheritance hypothesis in Drosophila for a metabolic phenotype that they are studying. Because you just got started in the lab, the professor tells you are not allowed to use any high-end high-tech resources to perform your experiments and to collect data. The only resources you have access to are the various stocks of Drosophila available in the incubators, the resources to feed the flies and to transfer the flies from vial to vial to perform crosses, and tools to measure the metabolic phenotype of interest.
Describe an experimental approach using crosses you could follow that could potentially provide you with data to support the biparental mtDNA inheritance hypothesis?

- Gunter Korge examined several proteins that are secreted from the salivary glands of Drosophila melanogaster during larval development . One protein, called protein fraction 4, was encoded by a gene found by deletion mapping to be located on the X chromosome at position 3C. Korge observed that, about 5 hours before the first synthesis of protein fraction 4, an expanded and puffed-out region formed on the X chromosome at position 3C. This chromosome puff disappeared before the end of the third larval instar stage, when the synthesis of protein fraction 4 ceased. He observed that there was no puff at position 3C in a special strain of flies that lacked secretion of protein fraction 4. Explain these results. What is the chromosome puff at region 3, and why does its appearance and disappearance roughly coincide with the secretion of protein fraction 4?arrow_forwardExplain how loss-of-function mutations in the following categories of genes would affect the morphologies of Drosophila larvae: A. Gap genes B. Pair-rule genes C. Segment-polarity genesarrow_forwardSeveral Drosophila species with unspotted wings are descended from a spotted ancestor.
