Karyotype Analysis - Explaining Genetic Disorders

There is this fictious bug that has a duplication disorder, causing it to have 2 heads, banding on the wings, and additional body segments.

How can a duplication of a chromosome of the first pair produce a double head and, at the same time, affect the wing pigmentation and body segmentation?

I don't understand why :( Please help.

Also:

What kind of information would be required if karyotype analysis were to be used to detect the genetic disorders of real organisms?
