B) Yes.Duplicated regions increase gene dosage,which affects processes like development that require specific amounts of protein for completion.
C) No.Duplicated regions of chromosomes are looped out and lost during meiosis.
D) No.Duplicated regions of chromosomes do NOT affect gene dosage,because the cell can compensate for extra copies of genes.
