Monosomy

   Also found in: Dictionary/thesaurus, Medical, Wikipedia 0.01 sec.
monosomy [′män·ə‚sōm·ē]
(genetics)
The condition in which one chromosome of a pair is missing a diploid organism.

Monosomy 

the absence of one chromosome from the complement of a diploid organism. A monosomic is a cell or organism which has a single chromosome of a homologous pair. Monosomy is the result of disruption during the separation of homologous chromosomes. It occurs most often in the sex cells during meiosis but is also possible in the somatic cells during mitosis. For example, individuals suffering from Turner’s syndrome (Shereshevskii-Turner syndrome) are monosomics for the X chromosome.
