  1. X type: a = acrocentric, thin = C-band restricted to the centromere, thick = C-band occupied the region next to the centromere, sa-e = subacrocentric with euchromatic short arm, sa-h = subacrocentric with heterochromatic short arm, a slash between two numbers indicates imprecise identification of the bivalent, Co-1 = coexistence site (X0/XY).
