In pea plants, individuals that are Pp for the alleles that code for flower color will have purple flowers. What is the phenotype?

The blending of the phenotype of the parents in the offspring is known as incomplete. colors of flowers can show incomplete dominance if a red flower is crossed with a white flower and their offspring are pink.
A phenotype is the physical trait or feature of an organism that is the effect of a particular genotype. Flower color of snapdragons is one example of a phenotype, and the color is determined by which alleles comprise the genotype. Plants that are homozygous for the flower color alleles are either white or red. Heterozygous snapdragons are pink.
When two alleles are co-dominant to each other, it is called complementary factor. For example gene A & B are responsible to contribute red flower color. When present individually in dominant condition, only white flowers are produced. When both these genes combine, the result brings red flowers. Thus when such individuals with white color are crossed, all F1 plants produce red flowers but in F2 generation, the plants segregate in the phenotypic ratio of 9:7. That is 9 plants with red flowers and 7 plants with white flowers.
It is called CODOMINANCE if the alleles each express when the phenotype is heterozygous. Let's look at the following situation. There are snapdragon flowers that are homozygous (having 2 of the same allele) for red. Let's call them R. There are also snapdragon flowers that are homozygous for white. Let's call them r. If you take one of the RR flowers and breed it with a rr flower, you will get Rr. If one of the alleles is dominant, then the flower will be the color of the dominant allele. If R (red) is the dominant allele, then all of the offspring will be red; if r (white) is the dominant allele, then they will be white. However, if they are codominant, then if the genotype is heterozygous (Rr), then the alleles will both express- in this case, the offspring would be pink. Hope I helped!
If you cross a red 4 O'clock with a white 4 O'clock, the phenotype will be pink This is because red has incomplete dominance over white, so the alleles blend. If yellow is crossed with white, the flowers are always yellow.

it is an observable expression of somethings genotype, that is the alleles that the organism has i.e a red flower may be homozygous containing two 'red pigment alleles' (RR) this is its genotype, its phenotype is the red colour of its petals
A trait that exhibits incomplete dominance, is one in which the heterozygous offspring will have a phenotype that is a blend between the two parent organisms. An example of this is when a homozygous red sweet pea flower crossed with a homozygous white sweet pea flower, their offspring will be heterozygous and have the pink phenotype, rather than either red or white. So, the homozygous red flower will be red, the homozygous white flower will be white, and the heterozygous flower will be pink. So there are three possible phenotypes in incomplete dominance. There are also no dominant or recessives genotypes.
