In humans the haploid chromosome number is
With the exception of identical twins, all humans show significant variation in genomic DNA sequences. The human reference genome (HRG) is used as a standard sequence reference. There are several important points concerning the human reference genome: • The HRG is a haploid sequence. Each chromosome is represented once.
