2. in what ways are the mutations described in steps 5-6 and 7-8 different from those described in steps 9-10 and 11-12? these are for the question5,7,9,115.if you are making the model by hand: add an additional pipe cleaner to position 21. an individual who has an additional chromosome in position 21 suffers from down syndrome.   7. if you are making the model by hand: remove the additional pipe cleaner you added in step 4. now remove one of the x chromosomes. an individual who has only one x chromosome suffers from a condition called turner syndrome.   9.if you are making the model by hand: return the x chromosome that you removed in step 5. now cut off a portion of one of the position 5 chromosomes. an individual who is missing a part of chromosome 5 suffers from cris du chat syndrome (cat-cry syndrome). draw a labeled diagram of this model.   11.if you are making the model by hand: replace the cut chromosome with a normal-length chromosome. now cut off a portion of both copies of chromosome 7. deletion of specific sections of both copies of chromosome 7 results in cystic fibrosis. draw a labeled diagram of this model.
