Mendel observed that all the offspring had purple flowers, showing that purple is dominant over white in pea plants. He discovered the principle of dominance and the concept of alleles.
Make a Punnet Square:White HETEROZYGOUS---WwRed HOMOZYGOUS--ww (this one is recessive because the white characteristic dominated in the heterozygous type)So:W ww Ww www Ww wwThese four are the potential types of the offspring, they will either be HETEROZYGOUS WHITE or HOMOZYGOUS RED, no homozygous white

Mendel did his experiments by using pea plants with various traits like the color of the flower, the shape of the seeds, the height of the plants etc and studied how those traits behave when crossed. For example, what happens when a short plant with red color flowers was crossed with a tall plant with purple colored flower etc.
He got purple flowers, because purple is dominant over white, and a plant with the combination of purple and white will be purple. P being the purple gene, p being the white, Pp will be purple, just like PP. Only pp will be white.
The plant you are referring to is likely lavender. Lavender is cultivated for its fragrant purple flowers and can be used to extract oil, which is commonly used for flavoring in cooking and baking. The oil has a floral and slightly sweet flavor that enhances both savory and sweet dishes.
purple is dominant over white in Mendel's pea plant experiment, meaning that the offspring inherited at least one purple allele from the purple parent. This resulted in all the offspring showing the purple trait.
All the offspring were purple because Mendel was dealing with simple genetic dominance. The purple true breeding parent was homozygous dominant and the true breeding white parent was homozygous recessive. When those two are crossed they create only heterozygous offspring (look up a punnett) and since this is simple dominance those heterozygous will show the phenotype of the dominant allele which is purple.
Mendel crossed true-breeding pea plants with contrasting traits in his first generation experiments. Specifically, he crossed a true-breeding purple-flowered plant with a true-breeding white-flowered plant.
PP X ww or Pw X ww Because all Purple flower plants are dominant and express the color purple. This can be seen in a homozygous cross, or a heterozygous cross, ( shown above ) White plants, to breed true, must be in homozygous condition.
The results suggest that the allele for purple flowers is dominant (P) and the allele for white flowers is recessive (p). The Punnett square for the cross would show a 3:1 ratio of purple to white flowered offspring, as predicted by Mendel's laws of inheritance. This indicates that the purple flower trait is dominant and the white flower trait is recessive.
They are fine; expected ratios might not be seen simply due to chance.
100% percent of the plants expressed the dominate trait ........................................................................................ what do u get when u mix purple with purple you get 100% purple :) simple peace of cake !
It can happen when both parents are a heterozygous

White flowered peas are wrinkled whereas Purple coloured flower peas are round and small in shape. white flowered peas have more sugar contents whereas purple flowered seeds have less sugar content and also the brown spots are present on the seeds whereas in former brown spots are absent. white lowered seeds are large in size in comparison to purple flowered seeds.
