Q. The total number of progeny obtained through dihybrid cross of Mendel is 1280 in $F_{2}$-generation. How many are recombinants?
A) 240
B) 360
C) 480
D) 720
Explanation
In Mendel’s dihybrid cross out of 16 progenies, 6 are recombinants so in case of 1280 progenies, the recombinants are =$\frac{1280 \times 6}{16} = 480\ progenies.$
