Explanation:
The RNA world hypothesis stipulates that RNA used to store genetic information before the evolution of DNA. RNA, however, is very unstable and it is believed it is the reason for the evolution of DNA which is a more stable form of storing genetic information of cells.
The RNA world hypothesis is supported by the fact that RNA is multifaceted and can also catalyse reactions –like protein enzymes, makes up ribosomes, and can self replicate.

Phenotype is the Visible expression of a Character
Also, with the help of a punet's square we will come to know to the Phenotypic Ratio is 3:1 where the purple flowers are dominant to white flowers where as if we take a Genotypic ration it doesn't show the Visible expression of a character, it only shows the genitical constituion of a character! If we take "percents", then it could be the Genotype "Percents" or Phenotype "Percents"
