Height among red stalk plants is divided into tall, medium and short. From tests, scientists know it is governed by two alleles of the same gene. It is known that tall plants and short plants are homozygous. What is the genotype of the medium plant? Explain your reasoning in one to two sentences. A cross between a medium plant and a tall plant occurs. What would be the genotypes? Show your work/explain your reasoning. Can medium plants be true breeding (i.e. be bred with other medium plants to ALWAYS produce medium plants)? Explain your reasoning.

Tall plant (D) is dominant to dwaf (d), and purple flower color (W) is dominant to white flower color (w). In order to determine the genotype of a tall plant with purple flowers, you decide to conduct a test cross. What should be the genotype of the plant you use to carry out the test cross?

You identify a gene that determines the size of the pods of a pea plant. To study the phenotype associated with this trait, you cross a plant that is homozygous for the “long pod” allele with a pea plant that is homozygote for “short pod” allele. When measuring the length of the pods of the parents and resulting offspring, you obtain the following data: Plant Length (cm) Homozygous (“Wide” allele) 15 cm Homozygous (“Short” allele) 4 cm Resulting cross breed 9 cm What can you conclude about this phenotype/trait? Long and short alleles are codominant Wide allele shows incomplete dominance over the short allele Wide allele shows complete dominance over the short allele Short allele shows complete dominance over the long allele The wide and short genes are linked
A plant geneticist is examining the mode of inheritance of flower color in two closely related species of exotic plants. The first species may have two pure-breeding lines—one produces a distinct red flower; and the other produces flowers with no color at all, or very pale yellow flowers. However, she cannot be sure. A cross of these varieties produces all pink-flowered progeny. The second species exhibits similar pure-breeding varieties; that is, one variety produces red flowers; and the other produces an albino or very pale yellow flower. A cross of these two varieties, however, produces orange-flowered progeny exclusively. Analyze the mode of inheritance of flower color in these two plant species.
A horticulturist has a purple plant and a white plant. The horticulturist knows that purple is dominant over white. When they are bred, all of the resulting offspring are purple. What is the most likely genotype of the parent or original purple plant?
In Mendelfruit plants, fruit may be either round (RR), long (rr) or oval (Rr). Cross two oval-fruit plants. What is the phenotypic ratio of the resulting offspring? (what do they LOOK LIKE?) Cross a round-fruit plant and an oval-fruit plant. Give the phenotypic ratio of the offspring.
Show the cross between a plant which is tall and purple, heterozygous for both traits AND a plant which is short and purple; heterozygous for purple flowers. Use the dihybrid template printout from above for this cross. Insert your picture by clicking on the picture frame and ensure that your picture includes your name.
Imagine you are crossing two plants that have these two genotypes—Tt and tt. What are the two genotypes of the gametes that the Tt plant can make? What is the one genotype of the gametes that the tt plant can make? Set up a Punnett square to analyze the cross. Does the Punnett square need to have four boxes or just two? If you were crossing a TT plant with a tt plant, how many boxes would be necessary in a Punnett square?
Colored aleurone in the kernels of corn is due to the dominant allele R. The recessive allele r, when homozygous, produces colorless aleurone. The plant color (not kernel color) is controlled by another gene with two alleles, Y and y. The dominant Y allele results in green color, whereas the homozygous presence of the recessive y allele causes the plant to appear yellow. In a testcross between a plant of unknown genotype and phenotype and a plant that is homozygous recessive for both traits, the following progeny were obtained: colored, green 88colored, yellow 12colorless, green 8colorless, yellow 92Explain how these results were obtained by determining theexact genotype and phenotype of the unknown plant, including the precise association of the two genes on the homologs (i.e., the arrangement).
In peas, tall (T) is dominant to short (t). A homozygous tall plant is cross with a short plant. The F1 are self fertilized to produce the F2. Both tall and short plants appear in the F2. If the tall F2 are self fertilized, what types of offspring and proportions will be produced? (Show all your work) please use the punnet square
