In Jimson weed (D atsura stramonicum), pollen with extr achromosomes DO NOT survive, but female gametes (ovum) areviable. Knowing how meiosis might occur in a trisomic organism (aplant in this case), predict the male and female gametes that mightform in the following trisomic plant. Also, determine which gametewill produce disomic zygotes and which gametes will produce2n+1trisomic zygotes. Assume that tetrasomic zygotes do notsurvive.
