A chromosome is a DNA molecule with part or all of the genetic material (genome) of an organism. Prokaryotes usually have one single circular chromosome, whereas most eukaryotes are diploid, like humans. Chromosomes in eukaryotes are composed of chromatin fiber. Chromatin fiber is made of nucleosomes. A nucleosome is a histone octamer with part of a longer DNA strand attached to and wrapped around it.
Human's diploid cell has 46 chromosomes, of which, 23 are from mother and 23 from father.Haploid refers to half the total number of chromosomes in a cell.Haploid number of chromosomes occur in gamete or germ line cells.a haploid human gamete cell would have 23 chromosomes only.
