Chromosomal Drift, a New Phenomenon in Plants

A seasonal shift in chromosome number of reproductive cells of Claytonia virginica, which coincided with near-drought conditions, resulted in a chromosome complement new to the population. The number reappeared 2 years later, the minimum time required for plants of that generation to produce flowers. Moreover, the chromosome number of root cells commonly differed from aerial organs of the same plant.
