... The expected and observed results of the experiment (P18.1b) Aim: The main objective of this experiment is to investigate dihybrid inheritance and understand the basic genetic and the process of division and also to compare expected and observed results between test tube A and B. Procedure * Two breading tubes are set: * Breading tube A- 6 males (black body) and 6 females (vestigal wings) * Breading tube B- 6males (vestigal) and 6 females (black body) * Both vestigal and black body flies are put in separate tubes to ensure they are not sexually linked. * After flies are bread they are put to sleep by substance called fly-nap. This will put them to sleep, allowing me to separate and count them. OBSERVED RESULTS TUBE A * MALE = BLACK BODIED, NORMAL WINGS (bbTT) * FEMALE = NORMAL BODY, VESTIGAL WINGS (BBtt) Parent's bbTT X BBtt F1 12 males: all normal body, normal wings 14females:
