Answer:
The F2 generation can be explained because the alleles for flower colour and pollen shape are linked.
Explanation:
<em>When two alleles are linked on the same chromosome, there is a high tendency for the alleles to be inherited together. Consequently, the frequency of the alleles recombining in subsequent generations is low.</em>
This is what Bateson and Punnet observed. There exist a linkage between P and L alleles and also p and l alleles, thereby increasing their frequencies  of occurring together and decreasing the frequency of their recombination.
Thus, the F2 generation observed by Bateson and Punnet is due to linkage of alleles.
