#chromosome  a threadlike body in the cell nucleus that carries the genes in a linear order
  supertype:  #body.natural_object  an individual 3-dimensional object that has mass and that is distinguishable from other objects; "heavenly body"
  part:  #nucleolus_organizer  #gene  #chromatid  #centromere
  part of:  #cell_nucleus
  subtype:  #sex_chromosome__sexchromosome  a chromosome that determines the sex of an individual; "mammals normally have two sex chromosomes"
     subtype:  #X_chromosome  the sex chromosome that is present in both sexes: singly in males and doubly in females; "human females normally have two X chromosomes"
     subtype:  #XX  (genetics) normal complement of sex chromosomes in a female
     subtype:  #XXX  (genetics) abnormal complement of three X chromosomes in a female
     subtype:  #XXY  (genetics) abnormal complement of sex hormones in a male resulting in Klinefelter's syndrome
     subtype:  #XY  (genetics) normal complement of sex hormones in a male
     subtype:  #XYY  (genetics) abnormal complement of sex hormones in a male who has two Y chromosomes
     subtype:  #Y_chromosome  the sex chromosome that is carried by men; "human males normally have one X chromosome and one Y chromosome"
  subtype:  #autosome__somatic_chromosome__somaticchromosome  any chromosome that is not a sex chromosome; appear in pairs in body cells but as single chromosomes in spermatozoa
  subtype:  #acentric_chromosome  a chromosome lacking a centromere
  subtype:  #acrocentric_chromosome__acrocentricchromosome  a chromosome with the centromere near one end so that one chromosomal arm is short and one is long
  subtype:  #metacentric_chromosome__metacentricchromosome  a chromosome having two equal arms because the centromere is in median position
  subtype:  #telocentric_chromosome__telocentricchromosome  a chromosome like a straight rod with the centromere in terminal position
