Chromosome inheritance in reproduction Steps:

• Gametes P and Q fuse during fertilization to form diploid zygote R.
• Cell R undergoes meiosis, involving two divisions, to produce four haploid gametes S, T, U, and V.
• Without the diagram, specific chromosome numbers cannot be determined.
• Standard biology assumes P and Q are haploid (n), R is diploid (2n), and S–V are haploid (n), but diagram details are needed for verification.

Not enough information to confirm any option, including B.

Why the others are wrong:

• A, C, D: Cannot evaluate without diagram showing exact counts.

Final answer: Not enough information.
