Summary
The frequency of association of acrocentric chromosomes is examined in 20 Down's syndrome children, their parents, and 60 controls. Chromosome 21 enters into satellite associations most frequently, and chromosome 15 least. The parents of Down's syndrome children do not show any increased tendency for satellite association of chromosome 21 or indeed any other acrocentric.
