If red color is dominant, (RR) and white is recessive, (rr) then crossing a homozygous red plant with a homozygous white plant will produce 100% red offspring. This is the F1 generation. These F1 offspring will be 100% heterozygous (Rr).
Subsequent crosses of these offspring in the second generation (F2) will produce 75% red and 25% white offspring phenotypically (the visual appearance of the color, The genotype ratio will 1 RR: 2 Rr:1rr with percentages of 25% homozygous red 50% heterozygous red and 25% homozygous white.

If a plant has an allele for red flower color and an allele for white flower color then that individual plant is for flower color?
Incomplete dominance which makes intermediate phenotypes.
Is the plant with flowers homozygous or Heterozygous?
Either. It matters. Since white is dominant, the allele (saying it is T for white and t for purple) could be either TT or Tt and still come out white. If the white flower is a purebred, then it is homozygous, therefore, TT. However, the flower could be white and be heterozygous.
How many alleles influence a phenotype in incomplete dominance?
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.
In pea plants purple flowers are dominant over white flowers. Two plants both heterozygous for the gene that controls flower color are crossed. What percentage of their offspring will have purple flow?

What is a phenotype-?
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.

If purple flower color is dominant over white flower color how can two purple flowered parents produce white flowering offspring?
It can happen when both parents are a heterozygous
If purple flower color is Dominic over white flower color how can two purple flowered parents produce white flowered offspring?
It can happen when both parents are a heterozygous
If purple flower color is dominant over white flower color how can two purple flowered parents produce while flowered offspring?
It can happen when both parents are a heterozygous
If purple flower color is dominant over white flowers color how can two purple flowered parents produce white flowered offspring?
It can happen when both parents are a heterozygous
purple petal color in pea plants is dominant to white petal color two heterozygous pea plants are crossed what is the ratio of the offspring with white petals to the number total number of offspring?
3:1 ratio Two pea plants, both heterozygous for flower color, are crossed. The offspring will show the dominant purple coloration in a 3:1 ratio

A white flower plantis is crossed with a plant that is heterozygous for the trait what percentage of the flower will be purple flowers?
1:2:1
What is it when alleles are neither dominant or recessive?
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!

How is a snap dragon an example of incomplete dominance?
When they don't have pink as their color so the "parents" had to of been either both white or both pink. That is how you can tell when snapdragons are not following the pattern of complete dominance.
