I found the exercise on the internet and attached is the representation of the fly's trisomy.
Correct answer:
<span>"Nondisjunction occurred in the male parent at the meiosis I division to produce an (n+1) sperm that fused with a normal (n) egg."
It is during meiosis I that the homologous chromosomes are divided into two new cells. In this case, if a trisomy is present, it means that during this segregation part during meiosis I, two homologous chromosomes were not separated (n</span>ondisjunction)<span> creating a gamete cell that had two copies of a chromosome (and another without any copy of that chromosome).
This error on meiosis I might have occurred in the male parent. As we can see from the schematic representation of the trisomy, there is two chromosomes with a wild allele (+). These alleles were only present in the male parent, as the female parent was homozygous for all genes, no wild allele (+).</span>

It is Chromosomal Inversion.
An inversion<span> is a </span>chromosome<span> rearrangement in which a segment of a </span>chromosome<span> is reversed end to end. An </span>inversion<span> occurs when a single-</span>chromosome<span> undergoes breakage and rearrangement within itself. </span>
The answer to the question of what relationship is classified as host-parasite. A parasitic relationship is one in which one organism, the parasite, lives off of another organism, the host, harming it and possibly causing death. A few examples of parasites are tapeworms, fleas, and barnacles. The parasite lives on or in the body of the host.
