Answer: The best explanation is that the flower has a recessive traits for pink-flower coloration

Explanation:

In genetics, recessive traits usually find expression in the second filial generation. At this stage there is a higher possibility of having a homozygous recessive gene which will find expression.

In the first generation, it is obvious that the blue-flower coloration has a dominance over the pink-flower coloration. However, on crossing of the first generation, it results in 14 homozygous plants for pink-flower coloration.
