1) The p arms of acrocentric chromosome is very short and hard to observe, but still present. The metacentric chromosomes are X-shaped, with the centromere in the middle so that the two arms of the chromosomes are almost equal.
2) Autosomes (22 pairs) are homologous in humans, whereas male sex chromosomes (XY) are non-homologous, while female sex chromosomes (XX) are homologous.
