One plant may contain hundreds of individual seeds, each resulting from a separate fertilization event. Asingle gene controls seed color with two alleles—the dominant allele results in black seeds, and the recessive allele results in brown seeds. In an experiment, a homozygous dominant plant is crossed with a heterozygous plant. Which of the following is the best prediction for the percentage of brown seeds that would result from this cross? 0% 25% 50% 75% 80% 100%

In corn plants, a dominant allele (K) allows kernel colour and a recessive allele (k) inhibits kernel colour when homozygous. On a different chromosome, the dominant gene P causes purple kernel colour and the homozygous recessive genotype causes red kernel colour.A true breeding white corn plant was crossed with a purple corn plant, yielding 50% red corn plants and 50% purple corn plants.What are the genotypes of the parental corn plants? Select one: a. KKPp kkpp b. KkPP kkPP c. kkPp KkPp d. KKPP kkPp
Sunflowers with small flowers measuring 10 cm in diameter are crossed with plants that have large flowers with a diameter of 16cm. All offspring in the F1 generation have medium size flowers with 13 cm in diameter. When crossing two F1 generation flowers, the F2 generation shows 4 flowers are 10 cm in diameter and 4 are 16 cm in diameter. Between these are 5 phenotypic classes with diameters intermediate to those at the extremes. What size flower makes up the most common phenotypic class?
Sunflowers with small flowers measuring 10 cm in diameter are crossed with plants that have large flowers with a diameter of 16cm. All offspring in the F1 generation have medium size flowers with 13 cm in diameter. When crossing two F1 generation flowers, the F2 generation shows 4 flowers are 10 cm in diameter and 4 are 16 cm in diameter. Between these are 5 phenotypic classes with diameters intermediate to those at the extremes. How much does each additive allele contribute to flower diameter?
In a hypothetical insect species, eye color may be purple or red and wings may be long or short. The table shows the results of two crosses where the parents were obtained from a mixed population that did not breed true. Cross 1 Cross 2 Parents red, long male x red, long female red, short male x purple, long female Progeny males: one-half red, long; one-half red, short females: all red, long males: one-half red, long; one-half red, short females: one-half red eyed, long; one-half red eyed, short What is the mode of inheritance for eye color in this insect? The eye-color gene is autosomal, and red is dominant to purple. The eye-color gene is X-linked, and red is dominant to purple. The eye-color gene is X-linked, and purple is dominant to red. The eye-color gene is autosomal, and purple is dominant to red. What is the mode of inheritance for wing size in this insect? The wing size gene is autosomal, and short is dominant to long. The wing size gene is X-linked, and long is dominant to…
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
In Primula vulgaris (primrose), purple flowers are dominant to white flowers, and short plants are dominant to tall plants. The genes controlling these two traits are on different chromosomes. You cross a true-breeding purple, short plant with a true-breeding white, tall plant and then intercross the resulting F1 offspring. In the F2 offspring, you find the following phenotypes: Purple, short Purple, tall 608 161 White, short White, tall 173 58 With your knowledge of the x' test, you will determine whether the outcomes of the F1 intercross corresponds to expectations based on Mendelian genetics. 1. What is your null hypothesis for the outcome of the F1 intercross? Write it here: 2. Based on your null hypothesis, how many individuals do you expect in each of the phenotypic classes? Write your expectations below. Purple, short Purple, tall White, short White, tall 3. What are the degrees of freedom for this test? Write your answer here:
In sweet pea plants, the trait for purple flowers (P) is dominant to the trait for red flowers (p).Similarly, the trait for long pollen (L) is dominant to the trait for round pollen (l).Two heterozygotes are crossed, yielding the following frequencies for the F1 generation:293 purple long plants;19 purple, round plants ;28 red, long plants ;87 red, round plantsUse the chi-square test to determine if these results are due to independent assortment. detailed explanation ?
