Answer: There are 9 different genotypes.
There are 4 different phenotypes.
3 offsprings out of 16 are green and rough
Explanation: The break down of the nine different genotypes are as follows:
Genotypes=>occurrence=>phenotypes
AABB ==> 1 => Green and smooth
AABb ==> 2 => Green and smooth AaBB ==> 2 => Green and smooth
AABb ==> 4 => Green and smooth
AAbb ==> 1 => Green and rough
Aabb ==> 2=> Green and rough
aaBB ==> 1 => yellow and smooth
aaBb ==> 2 => yellow and smooth
aabb ==>1 => yellow and rough
AAbb =1, Aabb =2 (a total of 3) are green and rough
