Intranuclear Distribution of Chiasmata in Normal Diploids and Interchange Heterozygotes of Pisum sativum L.

Abstract

Studies on intranuclear distribution of chiasmata were carried out in two types of plants of Pisum sativum, var. T 163-1) normal diploids and 2) interchange hetero-zygotes. In most of the plants the chiasmata were found to be distributed in an uncorrelated manner among the different bivalents of a cell. This was ascribed to the highly symmetrical karyotype possessed by Pisum sativum.
