In wild petunias, the allele for red flower color (R) is dominant over the allele for white flower color (r). We sample a population and find 750 plants have white flowers and 270 have red flowers. If the population is in HWE, what are the allele frequencies of R and r in this population? How many of the 270 plants that have red flowers are homozygous and how many are heterozygous at the flower color locus? Show your work and round allele frequencies to two decimal places

In wild petunias, the allele for red flower color (R) is dominant over the allele for white flower color (r). We sample a population and find 240 plants have white flowers and 85 have red flowers. If the population is in HWE, what are the allele frequencies of R and r in this population? How many of the 85 plants that have red flowers are homozygous and how many are heterozygous at the flower color locus?

In a species of plant, two genes control flower color. The red allele (R) is dominant to the white allele (r); the color producing allele (C) is dominant to the non color producing allele (c). You suspect that either an rr homozygote or a cc homozygote will produce white flowers. In other words, rr is epistatic to C, and cc is epistatic to R. to test your hypothesis, you allowed heterozygous plants (RrCc) to self fertilize and count the offspring....

Flower color in a wild rare orchid was found to be governed by a multiple allelic series with a dominance hierarchy of cR > cO > cY > cW. The allele cR produces red flowers; allele cO produces orange flowers in the homozygous condition but is lethal in any heterozygous state; allele cY produces yellow flowers; and allele cW produces white flowers. How many genotypes are possible among a population of orchid plants in the wild? (3 pts)

12. In snapdragons, the allele for tall plants is dominant to the allele for dwarf plants , and t he allele for red flowers is codominant with the allele for white flowers . The heterozygous condition for flower color is pink. Question – If a dwarf red snapdragon is crossed with a white snapdragon homozygous for tall, what are the probable genotypes and phenotypes of the F1 generation? a. tall and pink b. tall and red c. tall and white...

2. (4pts) In a strain of Petunia that normally have purple flowers, recessive and dominant mutations at the red color locus (R locus : R+ = wildtype allele, purple) lead to different flower colors. Plants that carry a particular dominant allele Ra have pink petals. Of the individuals that carry one allele of the dominant allele Rb roughly 20% have normally colored purple petals, the remaining 80% show a range of lighter red colors. Individuals that are homozygous for Rb...

8. You are studying an annual wildflower population. Flower color is either red or yellow and is controlled by a single locus with 2 alleles: R and y. Red is dominant to yellow, and both homozygous RR individuals and heterozygous individuals have red flowers, while yy individuals have yellow flowers. You have been studying this population for a long time and have seen fairly consistent allele frequencies for these two colors, with R=0.65 and y=0.35. Two years ago, a new...
