Which of the following is false? Group of answer choices With a pericentric inversion, there is no loss in genetic material. Haploinsufficiency is caused by a duplication event causing increased expression of a gene. An effect of aneuploidy is that it changes the dosages of some genes. Pseudodominance indicates that one of the homologous chromosomes has a deletion. Sterility is a possible effect of autopolyploid
