Chapter 8: Variations in Chromosome Number and
... Most members of diploid species contain two haploid sets of chromosomes, but there are variations from this pattern. These changes include a difference in chromosome number, deletion or duplication of genes, and rearrangement of genetic material among or within the chromosomes. All of these change ...
