Humans has 46 chromosomes and there 2n because each set has 23 and they are in pairs. Homologues chromosomes are the pairs of chromosomes that has the same length and centromere position; sister chromatids. Each pair is controlling the same herited character like eye colour. Autosomes are the other chromosomes that are not sex chromosomes (xy or xx it determines our sex) Haploid cells in gametes contain single set of chromosomes (n). In human, our diploid cell is 2n=46 and haploid cell is n=23; we have 22 autosome and one sex chromosomes.
