# The minimum weight of tomato obtained from a plant is 20g. The maximum weight of tomato obtained is 120g. What will be the weight of tomato obtained by crossing plant with genotype AAbb x aabb.

Asked by dr_pradip27121972 22nd April 2020, 3:04 PM

Minimum weight of tomato = 20 g = aabb

Maximum weight of tomato = 120 g = AABB

Parents – AAbb and aabb

Gametes – Ab and ab

Offspring - Aabb

AA = BB = 60, A = 30, B = 30

aa = bb = 10, a = 5, b = 5

Therefore, calculating the contribution for every gene, we get-

Aabb = 30 + 5 + 5 + 5 = 45 g

So, the weight of the progeny tomato = 45 g
