The zygomere as hypothetical unit of chromosome pairing initiation

Genetica Aims and scope Submit manuscript

Abstract

On the basis of indirect evidence from meiotic chromosome associations and genetic experiments, a working hypothesis on the initial stages of chromosome pairing is proposed and examples of application are given. It involves the assumption of functional units of chromosome pairing initiation that are provisionally named “zygomeres”. Possible analogies with centromere and nucleolar organized are discussed.
