well for a starters, "r" is obviously recessive as you didnt use any upper case lettering. if both flowers have homozygous recessive (homo being same) genes, then, with the use of a PUNNET SQUARE, you would be able to work out that any offspring that the flowers will have, will also have homozygous recessive genes (white).
so.. sort of like this...

sorry if its kinda hard to understand :P lol. otherwise search up punnet sqaures. helped me a lot. :P
What else can I help you with?
How do you set this up Two heterodox red flowers (white flowers are recessive) are crossed.?
When crossing two heterozygous red flowers (Rr), you would use a Punnett square to determine the possible genotypes and phenotypes of the offspring. In this case, the genotypes of the parents are Rr x Rr. The possible offspring genotypes would be RR, Rr, and rr, with a phenotypic ratio of 1 red : 2 pink : 1 white flower.
What is the genotype of a red flower crossed with a blue flower?
The genotype would depend on the genetic makeup of the red and blue flowers. If red is represented by 'RR' and blue is represented by 'bb', the offspring would all be Rr (heterozygous) for the flower color gene.
When traits are inherited in an incomplete dominance pattern what is true about the phenotype of the heterozygotes?
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.
In sweet pea plant R is the allele for red flowers and r is the allele for white flowers a. If an RR plant and an rr plant are crossed what will be the outcome of their offsprings?
All of the offspring will be red, since each of the four offspring receive the dominant red allele (R). Therefore, the offspring will all have the genotype Rr and a phenotype of red.
If a homozygous red flower is crossed with a white flower what percentage of their offspring will red have?
Assuming that white is recessive to red in this case, then the off spring would all be red but they would be heterozygous red (Rr).
If a Red (RR) and White flower (rr) were crossbred resulting in 100 Rr what phenotype(s) would been seen according to the rules of IN-complete dominance?
In incomplete dominance, the phenotype of the offspring is a blend of the parent traits. If a red flower (RR) is crossed with a white flower (rr), all offspring (Rr) would exhibit a phenotype that is intermediate between red and white, often resulting in pink flowers. Therefore, the observed phenotype in this case would be pink.
After crossing purebred red (dominant) and purebred white (recessive) flowers pink flowers appeared. Using symbols show the cross between pink and white flowers.?
In this scenario, the red flower (R) is dominant, while the white flower (r) is recessive. The pink flower (Rr) is a result of incomplete dominance. When crossing a pink flower (Rr) with a white flower (rr), the possible offspring genotypes are Rr (pink) and rr (white). The Punnett square for this cross would look like this: R | r ---------------- r | Rr | rr ---------------- r | Rr | rr The phenotypic ratio would be 50% pink and 50% white flowers.
What is the proportion of the monohybrid backcross between a red flower and a white flower?
The backcross between a heterozygous (monohybrid) red flower plant (Rr) and a homozygous recessive white flower plant (rr) would produce a ratio of 1Rr:1rr. So you would expect half of the offspring to be red (Rr) and half the offspring to be white (rr).

If a white flower is crossed with a red flower and a pink flower is produced this is called?
incomplete dominance

What are the phenotypes and genotypes of the offspring from the mating of a red carnation and a pink carnation for incomplete dominance?
The red color is RR and pink is Rr. RR is red, rr is white and Rr is pink. Cross the two: RR (red) and Rr (pink). You will get RR and Rr in a 1:1 ratio. You will not get any rr (white).The red color is RR and pink is Rr. RR is red, rr is white and Rr is pink. Cross the two: RR (red) and Rr (pink). You will get RR and Rr in a 1:1 ratio. You will not get any rr (white).
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
The heterozygous of red and white flower color which was co-dominant would be?
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.
