Chapter 5, Problem 15P

Three dominant traits of corn seedlings, tunicate seed( T– ), glossy appearance ( G– ), and liguled stem ( L– ), arestudied along with their recessive counterparts, nontunicate ( tt ), nonglossy ( gg ), and liguleless( ll ). A trihybrid plantwith the three dominant traits is crossed to a nontunicate, nonglossy, liguleless plant. Kernels on ears of progenyplants are scored for the traits, with the following results:

a. Is there evidence of genetic linkage among any of thesegene pairs? If so, identify the evidence.

b. Is there evidence of independent assortment among any of these gene pairs? If so, identify the evidence.

c. Using the gene symbols given above, write the genotypes of F1 and F2 plants.

d. If evidence of linkage is present, calculate the recombination fraction(s) from the data presented.

e. Could all three genes be carried on the same chromosome? Discuss why or why not.

Height of the plant  if a homozygous tall pea plant is crossed with a homozygous short pea plant, what are the possible genotype and phenotypes of the offspring?  Legend:  T- tall pea plant  t- short pea plant  Genotypes of the parents TT x tt Question  1. what is the genotypic ratio 2. what are the possible phenotypes of the offspring? 3. What is the phenotypic ratio? 4. what is the probability of having a short trait?
Question: Suppose the progeny were crossed. Fill in the Punnett Squares below and answer the following questions.   Seed Color Seed Shape R r A a                         In a pea plant experiment, the allele (R) producing yellow seed color is dominant, and the allele (r) producing green seed color is recessive. A homozygous recessive genotype would produce green seeds. Similarly, the allele (A) producing round seed shape is dominant to the allele (a) that produces wrinkled seed shape. A homozygous recessive genotype would produce wrinkled seeds. Both traits sort independently of each other. Given a pure-breeding cross between a round, green pea plant and a wrinkled yellow plant, complete the rest of the Punnett Squares below, and answer the following questions.  R R A A     RA Ra     Ra ra
