Drosophila melanogaster is a fly, distributed worldwide with the exception of extremes ofaltitude or latitude. Its claim to fame is that, for the last 100 years or so, it has been a favouriteorganism for biological research, initially in the field of genetics.The shape of the wings can vary. The wild type have normal shaped wings.Some flies have crumpled shaped or vestigial wings.

Drosophila flies
1. What shape wing is the dominant trait? Explain your choice
.2. Given that the F2 generation was the result of crossing heterozygotes, what are thepossible genotypes of a fly with wild type wings?
3. How might we determine if this trait is sex-linked?
4 .What improvements could be made to the waythe practical work was carried out? What 4 safety steps are taken in the experiment?ConclusionWrite a conclusion to your experiment.
