2) Imagine a gene was discovered that was responsible for body color. The wild-type form allowsfor a tan body color and the mutant form causes a dark-brown body color. Following the standardDrosophila nomenclature, what would be the name of this gene: "tan" or "dark-brown"? Why/how doyou know?3) Following the same example from question 2 how would you write the diploid genotype of a tan fly?A dark-brown fly?4) Consider the crosses you did today. One investigates whether the genesare autosomal or sex-linked and the other one investigates whether twogenes are linked or unlinked. Clearly state the two possible outcomesof the two crosses that you set up today (what are the two possibilitiesof the monohybrid cross and what are the two possibilities of thedihybrid cross). Include the parental, F1, and F2 generations genotypesand phenotypes. (NOTE: you should have two possibilities for themonohybrid cross (one for autosomal + one for sex-linkage) and twopossibilities for the dihybrid cross (one for genetically linked genes +one for unlinked genes).
