Flowers have phenotypes because all living organism has a definite shape and color. It is also seen in other living organism. It is only the expression outwardly of the genes in the DNA.
In pea plants, individuals that are Pp for the alleles that code for flower color will have purple flowers. What is the phenotype?
Aa AA aa If A dominant, two phenotypes.
In incomplete dominance, the phenotype of the heterozygous individual will be intermediate between the two homozygous phenotypes. For example, if one allele leads to red flowers and another allele leads to white flowers, a heterozygous individual will have pink flowers.
To achieve 100 purple flower phenotypes while also allowing for white flower phenotypes in the next generation, you can cross a homozygous purple flower plant (PP) with a heterozygous purple flower plant (Pp). This will yield 50% PP and 50% Pp offspring, all displaying the purple phenotype. To introduce white flowers in the next generation, you can then cross the heterozygous offspring (Pp) among themselves, producing a 25% chance of white flowers (pp) in the subsequent generation.
The intermediate phenotypes tend to be selected against, resulting in stabilizing selection that favors the extreme phenotypes. This can lead to a reduction in genetic variation within the population, as individuals with intermediate traits are less likely to survive and reproduce.

25% WW, 50% Ww, 25% ww are the genotypes, therefore 25% purple homogeneous, 50% purple heterogeneous, 25% white homogeneous are the phenotypes.
Parental Phenotypes are when the offspring of two parents look like one of the two parents. for example, if a green wrinkled pea is crossed with a heterozygous yellow round pea the offspring are 1/4 yellow round, 1/4 green wrinkled, 1/4 yellow wrinkled, and 1/4 green round. the yellow round and green wrinkled look like the parents so they have parental phenotypes, whereas the yellow wrinkled and the green round have combinations of the parental phenotypes thus they have recombinant phenotypes.
In incomplete dominance, the phenotype of the heterozygous individual will be intermediate between the two homozygous phenotypes. For example, if one allele leads to red flowers and another allele leads to white flowers, a heterozygous individual will have pink flowers.
The possible genotypes of the offspring are Bb (heterozygous blue) and bb (white). The possible phenotypes are blue and white flowers. Each offspring will inherit one allele from each parent, resulting in a 50% chance of being blue (Bb) and 50% chance of being white (bb).
The intermediate phenotypes tend to be selected against, resulting in stabilizing selection that favors the extreme phenotypes. This can lead to a reduction in genetic variation within the population, as individuals with intermediate traits are less likely to survive and reproduce.

No.
phenotypes
because no one in this world has the same gene.They may have similar gene,but not the same
The gene sequence of a DNA determines the variation of genetic expression in phenotypes.
