TRIAL ONE:

Original parents:                                                                                                                                                                                female: wild type, male: sepia (SE)
I made a punnett square and expected that one quarter of the second round of offspring would have sepia eyes.
Phenotype             Number
Female: +            49
Male: +              48
F2:
 Phenotype                     Number     
Female: +                                35    
Male: +                                     44    
Female: SE                              17    
Male: SE                                   12      
 
My trial went as expected, the sepia eyes were clearly a recessive trait and gender didn’t seem to significantly impact the results.
TRIAL TWO:
I crossed four different types of traits in this trial, and I wasn’t quite sure what to expect. I thought that in the F1 maybe 1 quarter of the offspring would show recessive traits and in the F2, the offspring would be split into extremely small ratios.
Original parents:
Female: sepia, black bodied (SE, BL), male: bar eyed, cross veinless (B,CV)
F1:

            Phenotype                   Number     

Female: B                                  484       
Male: +                                    479        
 Total                                    963

 
F2:

 
          Phenotype                   Number       
Female: +                                  147         
Male: +                                    102         
Female: SE                                  48         
Male: SE                                    26         
Female: B                                  148         
Male: B                                     34         
Female: SE;B                                50         
Male: SE;B                                  13        
Male: CV                                    47    
Male: SE;CV                                 12         
Male: B;CV                                 104      
Male: SE;B;CV                               34         
Female: BL                                  41         
Male: BL                                    39         
Female: SE;BL                               16        
Male: SE;BL                                  7         
Female: B;BL                                46         
Male: B;BL                                  12         
Female: SE;B;BL                             17         
Male: SE;B;BL                                5         
Male: CV;BL                                 14    
Male: SE;CV;BL                               9    
Male: B;CV;BL                               31      
Male: SE;B;CV;BL                            11        
 Total                                   1013

This trial did not run as expected, as in the first round of offspring all of the females had barred eyes, and in the second there was an equal number of non barred eyes to barred for females, while males rarely had barred eyes. Additionally females never received the cross veinless trait, while many males did. In the F2 the ratios where somewhat what I expected, however I was shocked to see how dominant the bar eyed trait was in females.
