Monohybrid and dihybrid investigations
Monohybrid:
First the counting of the purple and yellow kernels of two different corns would take place.
This is monohybrid inheritance as it is a hybrid created by crossing two individuals with one
set of opposite qualities. After that the ratio of the purple to yellow kernels would take place
using the numbers counted previously.
Key :
S= smooth – this is dominant
s= wrinkly – this is recessive
P= purple- this is dominant
p = yellow- this is recessive
Results for corn one and two:
purple yellow ratio
Corn 1 398 145 3:1
Corn 2 259 271 1:1
M4 Results:
Chi squared calculation of corn 1:
Observed:
Purple: 398 yellow: 145 ratios: 3:1
Expected: 398+ 145 = 543 3+1 = 4 543/4 = 135. 75
