Abstract
Concordant/discordant associations at chromatid level were compared and found significant (P less than 0.05) in females with primary amenorrhea. This probably suggested that the acrocentric association pattern in this group of ASD and infertility did not follow a random segregation in subsequent cell divisions and that the concordant acrocentric chromosomes have regularly established physical connections with one another, held together for several cell cycles. It could only be speculated that the association of acrocentric chromosome anomalies in some females with abnormal sex chromosomes are due to this reason. In the event that chromosome association has a bearing on chromosome aberrations, the non-random pattern of acrocentric association probably would increase the choice for translocation and non disjunction in the somatic cells in females with primary amenorrhea during ontogenesis.
