{\mathrm{F}_2}

-generation. How many are recombinants?

View answer and explanation

Correct option: C

480

Option C (480) is correct because in a dihybrid cross, the recombinant phenotypes occur in 6/16 of the progeny. Therefore, with a total of 1280 progeny, the number of recombinants is (6/16) * 1280 = 480.
