QUESTION 7 2 1 Parent Cell Polyploidy sometimes occurs in plants and can more or less result in immediate sympatric speciation. Using the graphic above, fill in appropriate words about the sequence of events 1-3 that results in a polypoid species. Individuals of the parent species (parent cells; event 1) start off as and through a meiotic error produce 4 egg and sperm gametes (event 2) When such gametes fuse, a zygote results (event 3). If this zygote develops into a mature individual that mates back with the parental species, the resulting triploid backcrossed offspring is and is reproductively isolated from the parental species. The individual at event 3 is therefore a separate species from the parental species at event 1 based on the Occasionally, even the triploid backcrossed indivudals can reproduce asexually and persist. For example, some triploid, seedless (sterile) fruit varieties, such as many cultivated are artifically selected and maintained by humans through clonal propagation
