Meiotic nonhomologous coorientation in man

Abstract

The concept of meiotic co-orientation of non-homologous chromosomes as a model of meiosis, experimentally confirmed in Drosophila, was proposed in 1971 to explain the interchromosomal effect in humans, but has not received sufficient evidence since. The data of the “non-canonical” behavior of sex chromosomes presented in this article are the basis for recognizing the existence of this phenomenon in human spermatogenesis.
