What happens to alleles between the p generation and the f2 generation?

During the development of a gamete, the two alleles of the P generation separate.  Each gamete carries one allele from each parent which randomly pairs in the F1 generation. This mechanism repeats when F1 plants cross and yield F2 plants.  The outcome of the F2 generation would then have new combinations of alleles which can be different compared to the preceding generations.
