Answer:
Correct Answer: C
Solution:
The total number of progeny obtained through dihybrid cross of Mendel is 1280 in $ F_2 $ generation, 480 will be parental.
In a dihybrid cross, the ratio of pure to recombinant is 9 : 7.
So, when total progeny is 1280, 800 is pure and the rest are recombinant.
The calculation is as:
