Why do animals have different number of chromosomes?
Fusion is a common way for animal species to end up with a different number of chromosomes from their ancestors. The most likely explanation is that two chimp chromosomes fused together. Part of the reason scientists think that two chimp chromosomes fused together is that chromosomes almost never split apart.

Why do all cells in the human body have the same chromosomes?
The normal cells in the human body have the same number of chromosomes because they all originated from the same cell, called a zygote, that underwent… Do all cells have all chromosomes? Every cell in the human body contains 23 pairs of such chromosomes; our diploid number is therefore 46, our ‘haploid’ number 23.
