Answer:
it is quantitative variation it is dependent upon no. of capital genes the weight is control by two types Gene then for minimum it is recessive means aabb no capital later in it's weight is 20 gm and for maximum amount then all later are capital means AABB is 120 difference between them 120-20 =100 and total Gene are 4 then 100/4= 25gm means per capital gene contain 25 gm then AAbb×aabb then all offspring are Aabb in this offspring capital later is only one then it's weight is 25+20 means 45 gm hope you understand my solution

If all the 4 allele have similar role in the weight of the plant then the actual weight of the tomato which is obtained by crossing the plants with the given genotype will be equal to 45 gram.
Explanation:
- From the given example it is evident that each of the recessive allele have five gram to the fruit. Whereas the dominant allele provides or contributes 30 gram of weight to the fruit. The fruit which is formed by buy the crossing of the given combination will be Aabb.
- As a result of this there will be 1 dominant allele and three recessive allele. Hence the the weight will be equal to 30+ (3x5) = 45grams.
