Please submit your answer on Moodle by copying & pasting it into the textbox. Format as necessary Part A (4 points): Review autopolyploidy (Lecture 21). The new tetraploid species shown in the diagram below can grow up to be a viable hybrid that can self-fertilize. However, it is reproductively isolated from its diploid parent species – explain why that is. Be specific and clear about the genetic mechanisms Unreduced gamete with 6 chromosomes Karyotype of parent species Zygote ll、Meiotic error fertilization 2n = 6 4n= 12 Tetraploid Unreduced gamete with 6 chromosomes Part B (6 points): Your textbook explains allopolyploidy on p. 437 and Fig. 13.15 is helpful in understanding how this process works. How is this different from autopolyploidy? Discuss three important differences between allo- and autopolyploidy Part C (4 points): We’ve discussed apply/hawthorn maggot flies as an example of incipient species due to sympatric speciation. Suppose there’s a mutation in the apple maggot fly that reduces its preference for apple trees (they become equally attracted to both apple & hawthorn) while the hawthorn maggot flies’ preference for hawthorn is unaffected. What do you expect to happen and why?
