I believe that the most logical explanation for this is that the right primary bronchus is wider than the left one (and the right lung is larger than the left lung), therefore the right lung receives slightly more carcinogenic cigarette smoke with each puff. In lung cancer. the cancer cells usually arise from the epithelium lining of large bronchus.

Answer:
Red (1/4), Pink (1/2), white (1/4)
Explanation:
This question involves a single gene coding for flower colour in the snapdragon plants. The gene exhibits incomplete dominance, because the allele for red color (R) is incompletely dominant over the allele for white color (W), hence an intermediate phenotype is produced as pink color (RW).
The pink colored snapdragon plant is produced in the F1 generation. When these F1 offsprings are crossed i.e. RW (pink) × RW (pink), gametes with R and W alleles are produced by each F1 parent.
Using these gametes in a punnet square (see attached image), four possible offsprings with genotypes; RR, RW, RW and WW will be produced in the F2 generation.
RR offsprings (1/4)- Red flowered
RW offsprings (2/4 or 1/2)- Pink flowered
WW offsprings (1/4)- White flowered
