. Flower color in lilies is controlled by an incomplete dominance pattern. Suppose you have two lily plants, both with orange flowers. You cross the two plants and are surprised to find that, half the offspring are orange, but ~25% are red and ~25% are yellow. You decide that you like the red flowers and would like to make more. a) What cross would you perform to produce the most red flowered plants? b) Your mother decides she would like some of the orange flowered lilies. Which cross would give you the most orange flowered plants?
You experiment with the genetics of height in a plant. You cross a homozygous tall (TT) plant with a homozygous short (tt) plant. Describe what the genotype and phenotype of the F1 progeny would look like if the plants exhibited complete dominance. Now describe the expected results if the trait exhibited incomplete dominance. What about the F2 progeny, assuming you crossed the F1 progeny with each other?
In pea plants, round pea shape is dominant to wrinkled pea shape. If two pea plants that are true breeding for wrinkled peas are crossed, what shape of pea will the first generation of offspring have? O a. one quarter of the peas will be round and three quarters will be wrinkled O b. three quarters of the peas will be round and one quarter will be wrinkled O c. half of the flowers will be round and one quarter will be wrinkled O d. all of the peas will be wrinkled O e. all resulting peas will be round
In peas, yellow seed (Y) is dominant over green seed (y). Inthe F2 generation of a monohybrid cross that begins when adominant homozygote is crossed with a recessive homozygote,you would expecta. three plants with yellow seeds to every plant with greenseeds.b. plants with one yellow seed for every green seed.c. only plants with the genotype Yy.d. only plants that produce yellow seeds.e. Both c and d are correct.
In pea plants, purple flowers are dominant over white flowers. A heterozygous purple plant is crossed with a homozygous purple plant.What is the genotypic ratio of the offspringWhat is the phenotypic ratio of the offspring
Please use instructions from the pic Snapdragons show incomplete dominance in flower colour. A cross between red flowers and white flowers will produce pink flowers. If a white flower is crossed with a pink flower, what is the probability of producing a pink flower?
Yellow seed color is dominant to green seed color. A plant that has homozygous recessive genotype is crossed with a heterozygous plant. What is the probability of the offspring's phenotype? A. 75% yellow seedsB. 50% green seedsC. 75% green seedsD. 100% green seedsE. 100% yellow seeds
Suppose you identify a new gene in mice. One of its alleles specifies white fur color. A second allele specifies brown fur color. Mice also are seen as white and brown patches. Youwant to determine whether the relationship between the alleles is simple dominance (and if so which color is dominant) incomplete or co-dominance. What sorts of genetic crosses would give you the answer? On what types of observations would you base your answers? Name the type of inheritance.
In certain species of flies, eye color is controlled by sim-·ple dominance by a single pair of alleles. A red-eyed fly was crossed with a white-eyed fly, both of whose parents had white eyes. All of their offspring (both female and male) had red eyes.a. Which is dominant, the allele for red eyesor the allele for white eyes?b. What is the genotype of the white-eyed parents?c. If the white-eyed parent was mated with one of the red-eyed offspring, what phenotypic ratio wouldyou expect regarding eye color?
Honeybees are unusual in that male bees (drones) have only onecopy of each gene, but female bees have two copies of their genes.This difference arises because drones develop from eggs that havenot been fertilized by sperm cells. In bees, the trait of long wingsis dominant over short wings, and the trait of black eyes is dominant over white eyes. If a drone with short wings and black eyeswas mated to a queen bee that is heterozygous for both genes, what are the predicted genotypes and phenotypes of male and femaleoffspring? What are the phenotypic ratios if we assume an equalnumber of male and female offspring?
More Crosses with Pea Plants: The Principle of Independent Assortment Consider the following cross in pea plants, in which smooth pea shape is dominant to wrinkled, and yellow pea color is dominant to green. A plant with smooth yellow peas is crossed to a plant with wrinkled green peas. The offspring produced peas that were all smooth and yellow. What are the genotypes of the parents? What are the genotypes of the offspring?
More Crosses with Pea Plants: The Principle of Independent Assortment Determine the possible genotypes of the following parents by analyzing the phenotypes of their children. In this case, we will assume that brown eyes (B) is dominant to blue (b) and that right-handedness (R) is dominant to left-handedness (r). a. Parents: brown eyes, right-handed brown eyes, right-handed Offspring: 3/4 brown eyes, right-handed 1/4 blue eyes, right-handed b. Parents: brown eyes, right-handed blue eyes, right-handed Offspring: 6/16 blue eyes, right-handed 2/16 blue eyes, left-handed 6/16 brown eyes, right-handed 2/16 brown eyes, left-handed c. Parents: brown eyes, right-handed blue eyes, left-handed Offspring: 1/4 brown eyes, right-handed 1/4 brown eyes, left-handed 1/4 blue eyes, right-handed 1/4 blue eyes, left-handed
