Thus, the major idea that scholars like Ernst (2000, p. 187), Greenspan (2004, pp. 212 – 213), Ladiges et al. (2009, pp. 129 – 130 ), and Peters (2010) agree on is that Drosophila flies are invaluable samples for genetics tests of any complexity and purpose. Discussing the genetic peculiarities of the flies themselves, scholars like Ernst (2000, p. 189) and Greenspan (2004, p. 219) single out the short life cycles of Drosophila flies and the drastic changes in their morphological, or physical characteristics that can be observed in generation 2 (F2) is the parental generation (P) flies crossed represented different mutant species of Drosophila and the generation 1 (F1) species were rather similar in their characteristics.

Peters (2010) singles out eye color, body color, and cross veins as the major physical traits changed in the process of crossing various mutant species of Drosophila flies. Interestingly, this author points out that the major eye colors for Drosophila flies include brown, sepia, cinnabar, white, and vermillion, while bodies can be black, yellow, and ebony types. As for cross-veins, Peters (2010) singles out Drosophila flies that have cross veins and those that do not have them.
