The paperr presents the frequency of satellite associations (SA) of acrocentric chromosomes in 11 mothers and 11 fathers of children with trisomy 21 with reference to meiotic and mitotic nondisjunction.The control group consisted of 60 individuals of the both sexes at the age of 20-45.Satelite associations were investigated in the metaphase plates obtained from the culture of peripheral blood lymphocytes.The association index values (AI) in six mothers and six fatheers exceeded the mean AI value plus 2 standard deviations noted for the control group of women and men.The mean AI values for chromosome 21 in the group of fathers and mothers of children with trisomy 21 were significantly higher in comparison to the control of man and women.Associations 13-21, 21-21, 21-22 in the fgroup of mothers and 13-21, 15-21, 21-21, 21-22 in the group of fathers were observed more frequently than in control group.Associations 13-13-21, 13-21-21, 13-21-2, 21-21-22 occured more frequently in the group of parents of children with trisomy 21 than in the control.
