==Chromosome example==

The chromosome example, currently #15 on the list, is false.  The standard human has 46 chromosomes.  A human with Downs Syndrome has has 47.  If they were to mate, they would produce viable offspring.  However not all instances of having an extra chromosome result is problems such as Downs Syndrome, some have relatively no impact, most are far worse, and some provide benefits.  However I cannot recall a situation where it was beneficial in humans, I have read of cases where it has benefited other animals and plants.
