Nonhomologous synapsis of the XY during early pachynema in In(X)1H male mice.

Abstract

It has been previously supposed that meiotic synapsis is restricted to homology during early, but not late pachynema. The synaptic behavior of an inverted X chromosome, In(X)1H as reflected in the synaptonemal complexes of the sex chromosomes has been examined in microspread spermatocytes by electron microscopy and evidence of extensive nonhomologous synapsis between the X and Y during early pachynema has been obtained.
