Corn is bred for traits that improve its usefulness for specific purposes. Forexample, it may be bred to grow in various climates, to produce more corn, or tobe better tasting. These traits depend on the alleles inherited by the corn plant.Suppose that you are studying the color and texture of kernels on a cob. Kernelscan be either purple (R), which is the dominant color, or yellow (r), which is therecessive color. Kernels can also be smooth (T), which is the dominant texture, orwrinkled (t), which is the recessive texture. In this lab, you will predict theinheritance of alleles for two particular traits in a dihybrid cross by using aPunnett square. Allele Combinations and Punnett Squares continuedttt ttttttttt4. Predict Suppose corn plant C has a known genotype of RRTT. Could cornplants with cobs that had some yellow and wrinkled kernels be produced bycrossing Plant C with a plant with a genotype of your choice? Why or whynot?

Every gene has two or more contrasting alleles. Most of the crosses studied by Mendel works with two…

A farmer obtained pure seed of wheat variety (Galaxy-13) but unfortunately he has mixed it with other varieties in his field while he was planning to use that seed for next year. Being a plant breeder, suggest a method in detail to the farmer, that how he can get the pure seed again from that mixed lot
(b) A plant breeder wants to use selective breeding to produce corn with short stalKS and a high mass of grain. He could use the following varieties of com: varlety A varlety B varlety C long stalks short stalks long stalks high mass of grain low mass of grain low mass of grain (i) What would the plant breeder need to do to make sure he always produced corn with short stalks and a high mass of grain? Describe the three steps the breeder would use. (ii) Suggest one other characteristic that famers might like corn plants to have to increase the amount of corn produced.
Consider the following hypothetical gene a plant g&T produces a protein that impacts the stem length. There are two alleles for GT which produces long stem and tea little tea which results in short stint. Which of the following genome types above would have a different pheno type? And what would the phenotype be for the genotype?
A plant breeder wants to use selective breeding to produce corn with short stalks and a high mass of grain.He could use the following varieties of cor, A, Long stalks, high mass of grain, B, Short stalks, low mass of grain or c, Long Stalks, low mass of grain. What would the plant breeder need to do to make sure he always produced corn with a short stem and a high mass of grain? Describe three steps the breeder would use.
In com, colored aleurone (in the kernels) is due to the dominant allele R. The recessive allele r, when homozygous, produces colorless aleurone. The plant color (not the 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. Numbers of Offspring Phenotype Colored Aleurone & Green Plant 88 Colored Aleurone & Yellow Plant 12 Colorless Aleurone & Green Plant 8 Colorless Aleurone & Yellow Plant 92 Question: Determine the genotype and phenotype of the unknown plant, including the precise association of the two genes on the homologs (i.e. the map arrangement)
Why plant breeders intend to change the inheritance of crop plants? How plant breeders can change the heredity of crop plants? Explain your answer in briefly.
Different traits may be important in order to increase wheat yield. These traits may include short plant height, short and erect leaves, large and compact panicles, and resistance to shattering. Resistance to shattering is an important agronomic character for maximizing wheat yield, because plants with low susceptibility to shattering have reduced loss of grain mass during harvest. If you have determined that VG = 357, VD = 52, VI = 24 and VE = 5 for the shatter trait, what is the estimate for narrow sense heritability for the shatter trait?
Assuming you planted bean seeds that have been obtained from the same parent bean plant in three plots where growth conditions are the same except soil pH which varies as shown in the table attached which shows the effects of soil fertility on bean yields obtained from three plots where seeds from the same parent bean plant were obtained. a) is the trait, bean yield, qualitative (monogenic ) or quantitative (polygenic). Supoort tour answer with good reasoning.
From an agricultural point of view, discuss the advantages and disadvantagesof selective breeding. It is common for plant breeders to take two different, highly inbred strains, which are the product of many generations of selective breeding, and cross them to make hybrids. How does this approach overcome some of the disadvantages of selective breeding?
Two different genes control the expression of kernel colour in Mexican black corn: black pigment gene B and dotted pigment gene D. Gene B influences the expression of gene D. The dotted phenotype appears only when gene B is in the homozygous recessive state. A colourless variation occurs when both genes are homozygous recessive. What would be the phenotypic ratio of a test cross with a plant heterozygous for both traits? Your response must include a Punnett square with appropriate nomenclature. Show the ratio as whole numbers in their lowest form and their corresponding phenotypes.
Consider the following hypothetical gene a plant. Gene T produces a protein that impacts stem length. There are two alleles for gene T, T which produces long stems and t which results in short stems. If gene T displays incomplete dominance, which of the following genotypes above would have a different phenotype? and What would the phenotype be for this genotype?
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. étv MacBook Pro %23 $ & * 3 4 5 7 8. T Y D F H. J
