Scientific method for genetic studies

I have attached the full question, but in summary, it asks that I use scientific method to explain which genes are recessive and which are dominant.

Title: Heredity Lab
Instructions: Write a 1- page lab report using the scientific method to answer the following questions:
• State which genes are dominant (the genes that get expressed over the other genes) and which genes are recessive (the genes that will not be expressed when the dominant gene is present).
P = gene for purple flower
p= gene for white flower
P = trait for purple flower. It is the dominant gene.

p = trait for white flower. It is the recessive gene.

Pp - heterozygous for purple flower

pp - white flower

Gregor Mendel's studies laid the foundation for modern genetics. In a series of elegant experiments, Mendel was able to deduce the most fundamental laws of single-gene and multiple-gene inheritance without having the scientific data on chromosomes, their structure, or meiotic segregation. In this lab, you will incorporate these 2 pieces of the puzzle to interpret the experimental results that were obtained by Gregor Mendel in 1865.

Part 1: Using the lab animation, fill in the following data table to help you generate your hypothesis, outcomes, and analysis: https://class.aiuniv.edu/_layouts/MUSEViewer/Asset.aspx?MID=MU18806&aid=AT99992

How do you know which genes are which?

P = trait for purple flower. It is the dominant gene.

p = trait for white flower. It is the recessive gene.

Pp - heterozygous for purple flower

pp - white flower

Pp= purple flower self-pollinate itself
Pp X Pp

Punnett Square
½ P ½ p
P p
½ P ¼ PP ½ Pp
½ p ½ Pp ¼ pp

What is the ratio that is most likely to be observed across all traits?

Offsprings:
Genotypic ratio:

¼ PP
1/2Pp
¼ pp
ratio: 1: 2: 1
Phenotypic ratio: 3 purple: 1 white

Solution Summary

Mendel's pea plant experiment laid the foundation for genetic inheritance. By crossing pure breed pea plants, he had uncovered that the unit of inheritance is passed on to the next generation from each parents. The pair of alleles from each parents is passed on equally to the offsprings. He had formed the law of segregation. He had also stated that dominant alleles can be expressed with the exclusion of the other recessive alleles. The notion dominant over recessive comes into existing with Mendel's pea plant experiment. He had also uncovered the law of independent assortment when two genes can assort independently to the offsprings.
