Hi Yohana C., He discovered no such thing! Purple flower is a phenotype, not a genotype -- you would need to specify that the one parent was a true-breeding (i.e. homozygous) purple pea. The white allele is recessive, so one knows that that parent is homozygous for white.
Under the above-specified conditions, you would then find 100% purple-flowered (phenotype!) offspring. And they would all be heterozygous, with a dominant allele for purple, and a recessive one for white.
-- As you probably already have found out?---
