Question
1. You breed two rose species together one has large red flowers and has thorns, the other has small yellow flowers and is thornless. the F1s all have small red flowers and thorns. You cross these F1s with a large yellow flowered thornless tester the resulting offspring were:
109 large red thorns 91 large red thornless 92 large yellow thorns
111 large yellow thornless 110 small red thorns
89 small red thornless
88 small yellow thorns 109 small yellow thornless

Answer:
Chi-square vale = 7.94
Total phenotypes=8
Degrees of freedom= Total phenotypes-1= 8-1 =7
