According to Chargaff's rule, pyrimidine and purine occur in equal ration (1:1) in the DNA of all cells. Adenine (A) and Thymine (T) occur in equal proportion while Guanine (G) and Cytosine (C) occurs in equal proportion in the DNA of an organism. This pattern is repetitive and found in both DNA strands.

Explanation:
A cross between genotype AA BB is crossed with a plant with genotype aa bb will produce
Parent genotype:AABB x aabb
Gametes: AB x ab
F1 generation - AaBb
Since an uppercase letter contributes 4 g to weight and each allele represented by a lowercase letter contributes 1 g to weight.
Thus, 4+1 + 4 + 1 = 10g
