Abstract
Meiotic chromosomes of common beans (P. vulgaris) were stained with 45% iron propionic carmine to study changes in morphology during the condensation process at the diplotene stage. Chromosome morphology was studied with a stereo dissecting microscope at 20.times. using contact sheet prints of photomicrographs taken with a phase contrast system at 1000 .times.. The banding patterns of each chromosome are unique and can be used to identify that chromosome at diplotene. The relative chromosome length can only be used to separate the chromosomes into long and short classes because of the differential condensation rates of chromatic and achromatic chromosome segments. A set of diplotene chromosome diagrams is provided.This publication has 3 references indexed in Scilit:
