When you cross true-breeding tall and short tobacco plants you get an F1 that is intermediate in height. When this F1 is self-crossed, it yields an F2 with a continuous distribution of heights. What is the best explanation for these data? a. Height is determined by a single gene with incomplete dominance. b. Height is determined by a single gene with many alleles. c. Height is determined by the additive effects of many genes. d. Height is determined by epistatic genes.

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?
A. In corn, yellow kernels (Y) are dominant to white kernels (y). If you cross two plants with the Yy genotype, what percentage of the offspring will have yellow kernels? B.What percentage of the offspring will have the same genotype as the parent plants? C.Say you're also interested in corn plant height where tall plants (T) are dominant to short plants (t). You want to save some time and just cross your plants once. The P1 genotypes are YyTT and YYTt. Will you get any short plants with yellow kernels from this cross? Why or why not? D. If these traits, kernel color and height were linked, how would this affect your experimental outcomes? Would you expect the laws of Mendelian genetics to still apply? Why or why not ?
True breeding eggplant plants producing deep, purple colored fruit are crossed with true breeding plants producing white fruit. The offspring of this cross all produce lighter, violet fruit. The colors of the fruit are produced by the interactions of the two different alleles. A.Predict the genotype of the F1 plant. B. Predict the expected proportions and genotypes in the F2 generation, if F1 eggplants are crossed.
A true breeding plant that produces elongated fruits is crossed to a true breeding plant that produces round fruits. The offspring of this cross all have oval-shaped fruit. Which of the following is true? A. This involves two genes, one that controls the length of the fruit and one that controls the width. B. This long allele is epistatic over the short allele. C. The long allele is dominant over the short allele. D. The long allele is incompletely dominant over the short allele.
a. State a hypothesis explaining the inheritance of flower color in painted tongues. b. Assign genotypes to the parents, F₁ progeny, and F2 progeny for all five crosses. c. In a cross between true-breeding yellow and true-breeding lavender plants, all of the F1 progeny are bronze. If you used F₁ plants to produce and F2 generation, what phenotypes in what ratios would you expect? Are there any genotypes that might produce a phenotype that you cannot predict from earlier experiments, and if so, how might this alter the phenotypic ratios among the F2 progeny?
A tall pea plant with terminal flowers (flowers on the ends of the stems) is crossed with a short plant thathas axial flowers. All 72 offspring are tall with axial flowers. This is a dihybrid cross with the height andflower position traits showing independent assortment. a. Name the dominant and recessive alleles. b. Give the genotypes of the parents and offspring in this cross. c. Predict the F2 offspring when the tall-axial F1's are allowed to self pollinate.
A tall plant is crossed with a short plant, and the F1 progeny are all intermediate in size between the two parental plants. If the intermediate F1 progeny were allowed to self-pollinate, and the F2 progeny were mostly intermediate in size, but following a normal distribution (bell shaped curve) with some tall and some short, this would suggest: A. Incomplete dominance. B. Polygenic (multifactorial) inheritance. C. Complete dominance. D. Codominance.
Fruit flies are very useful model organisms that have been used to study genetics. One mutant recessive trait in fruit flies is called "eyeless" because it causes flies to have no eyes. Cross an eyeless fly with a homozygous normal fly. a. Draw the Punnett square. b. What is the genotyoe ratio of the offspring? c. What is the phenotype ratio of the offspring? d. What genetic problem is this? (monohybrid, dihybrid or multiple allele)

If you cross the F1 to the tall parent, what phenotype will result of the cross? What will be the ratio of the genotype? d. If you cross the F1 to the short parent, what phenotype will result of the cross? What will be the ratio of the genotype?
