							Hai,Tul Waghmode,
This question is related to genetics.
The answer is 20g of tomato size for each gene(12.5% of the genes).
The small alphabets denotes recessive character 100g tomato (size),where as 160g tomato (size) represents dominant genes.

Let us consider 160g as 100% weight of tomato
and 100g as less weight by 37.5% compared with the dominant tomato size.

From the above explanation there is a difference of
37.5% or 60g difference between dominant and recessive genes.

So divide the 60g excess equally to 3 genes (AA/BB/CC) that is 20g for each gene.
Hope you understood the answer.
