Answer:
Correct Answer: C
Solution:
[c] The total number of progeny obtained through dihybrid cross of Mendel is 1280 in $ F_2 $ generation, 480 will be recombinant.
In a dihybrid cross, the ratio of pure is to recombinant is 10 : 6.
So, when total progeny is 1280, 800 is pure and rest recombinant.
The calculation is as:
