(After Herbst.) maternal chromosomes behave normally at each division. The conclusion follows with much plausi- bility that the absence of paternal characters on one side is due to the absence of paternal chromosomes on that Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Morgan, Thomas Hunt, 1866-1945.
