Answer 2

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.
