Can someone me with punnett squares? biology

imagine that you are crossing two plants that are heterozygous for flower color and seed shape. the dominant and recessive alleles for these traits are:
purple flowers: p
white flowers: p
round seeds: r
wrinkled seeds: r

genotype of parent plant 1: pprr
genotype of parent plant 2: pprr

how will the alleles for these traits assort into the gametes that each parent might produce?

parent plant 1: pprr

gamete 1: pr
gamete 2: pr
gamete 3: pr
gamete 4: pr

parent plant 2: pprr

gamete 1: pr
gamete 2: pr
gamete 3: pr
gamete 4: pr

are these answers above correct? how would i fill out this punnett square? (i attached an image)
