Imagine a population 528 individual plants.  In this population, 4 % of the plants produce red flowers, and 9 % produce pink flowers. The remaining plants produce white flowers. Flower colour is attributed to a single locus with two  alleles. Red flowers are produced by plants that are homozygote for the R  allele.  White flowers are produced by plants that are homozygote for the W allele. Heterozygotes (RW)  produce pink flowers.  What is the expected (under Hardy-Weinberg equilibrium) number plants producing pink flowers in this population? Round your answer to the closest full number.

There are two incomplete-dominant alleles for petal color in a population of flowers. 36% of the flowers have red petals, 16% of the organisms have white petals, and 48% of the flowers have pink petals. What percentage of alleles in this population code for red petals (R)? Phenotype Genotype Red RR Pink Rr White rr

Imagine you cross two closely related plant varieties: Maize and teosinte. You hypothesize that different alleles at just 5 genes are responsible for all the trait differences between the two plants. You take two inbred parent lines and cross them together to produce an F1 and then cross two F1 individuals together to produce F2 offspring. What proportion of the offspring do you expect to look exactly like each of the parent lines if your hypothesis is correct? Please show work using punnet squares.

Scenario: plant species has flowers that can be red, pink, or white. Flower color is controlled by one gene with two alleles, A (p) and a (q). Red flowers are produced by AA homozygotes, pink flowers are produced by Aa heterozygotes and white flowers are produced by aa homozygotes. A recent survey of 100 of these plants found the following number of different flower colors: 75 plants with red flowers, 20 pink flowers, 5 white flowers.  Question: Among 500 plants,​​​​​​​ how many of the 'AA' genotype are expected under Hardy-Weinberg?

Flower color variation in Phlox drummondii living either in sympatry or allopatry with Phlox cuspidata has previously been studied. Phlox drummondii exist in four colors: light blue, dark blue, light red, and dark red. Each flower color is controlled by a specific combination of alleles. In allopatry, butterflies randomly pollinate Phlox drummondii flowers of all color types. In contrast, non-random pollination occurs between differently colored flowers when both Phlox species are living in sympatry. The graph depicts the relative fitness of the alleles that drive flower color in Phlox drummondii under conditions of sympatry or allopatry with Phlox cuspidata. Label each half of the graph with the term sympatry or allopatry based on the observed trend in the relative fitness of the alleles that control all four flower colors in Phlox drummondii.

A researcher at ASU is studying the exotic Unicorn Fairy plant. The plant has three genes of interest with the dominant alleles being T-tall, H=hairy leaves and P=purple flowers. The three genes are located in different chromosomes. A trihybrid plant is crossed with a plant that is heterozygous for T and homozygous recessive for the other two genes. What is the probability of getting offspring that is tall, has hairy leaves and white flowers? 9/64 5/8 8/64 O 3/64 O 3/16

An F, generation is the result of which mating described below? Select one: O a. Randomly mating any two parents of opposite sex together. cross out O b. Mating a true breeding female to a true breeding male. cross out O c. Mating the offspring of an F, generation back to their parents. cross out cross out O d. Mating any F, male to any F, female. cross out O e. Allowing the individuals from a single F, generation to mate among themselves. Clear my choice

Short is recessive to tall. Green pods are dominant to yellow as inflated pods are dominant to constricted pods. A pure-bred tall plant with green and inflated pods is crossed with a plant that is heterozygous for all of the traits. Calculate the probability of getting a plant seedling that is recessive for all of the traits. What is the probability of getting a tall plant with green and inflated pods?
