The American Naturalist Volume 39 by American Society Of Naturalists Pdf

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1905 edition. Excerpt: ...the second following immediately upon the first, and a segmentation of the protoplasm, sometimes by two successive divisions, and sometimes by a simultaneous cleavage, into four spores. The two mitoses present certain peculiarities in the structure and behavior of their chromosomes which are unlike the events of typical mitoses. The first is known as the heterotypic and the second as the homotypic mitosis. These peculiarities have been recognized for a long time and have furnished the subject of much investigation and contradictory explanations. They were briefly described in Section III (Amer. Nat., vol. 38, p. 740, Oct., 1904) but recent studies of Farmer and Moore (: 03: 05) have opened again a discussion which seemed closed at that time. The details of synapsis and the heterotypic and homotypic mitoses will be taken up under the caption, " Reduction of the Chromosomes." Contrary to a statement in Section III of these studies (Amer. Nat., vol. 38, p. 726, Oct., 1904) there is probably a deep significance in the fact that two mitoses are almost universally present in the spore mother-cell so that four spores are formed. It is probable that these mitoses are always heterotypic and homotypic, although this fact has only been clearly established in comparatively few favorable forms, and that they are indispensable to the mechanism of reduction phenomena. The latest accounts describe the first mitosis as the separation of the two portions of a bivalent chromosome, that is of two chromosomes joined either side by side or end to end, giving it a unique position among the mitoses of the life history. According to these theories the two mitoses of sporogenesis are features of a remarkable mechanism by which the paternal and maternal...
