Book excerpt: Excerpt from Chromosomes and Phylogeny in Crepis, Vol. 2: The Relationships of One Hundred Eight Species The first paper Of this series (hollingshead and Babcock, pre sented data on the number and morphology Of the chromosomes in sixty-seven species of Crepis and three other species belonging in closely related genera. Since then it has been possible to study the chromosomes of fifty additional species and. Subspecies, and it is now possible to discuss the bearing Of all these chromosome studies on the phylogenetic relation ships Of about half the species in the genus.

This book was released on 2018-09-08 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Chromosomes and Phylogeny in Crepis Where the number exceeds 12, the problem of distinguishing the various chromosomes becomes more difficult and in most cases it has been impossible to distinguish all the chromosome pairs in one plate, although various types are readily picked out. In those species with more than twenty chromosomes the plates for drawing were chosen with the primary aim of depicting clearly the number, and, second arily, of showing as many as possible of the chromosomes which could be distinguished by their particular morphology.

Available in PDF, EPUB and Kindle. Book excerpt: The question of how man has emerged must be as old as human thought itself. However, it was not until last century that, amidst a storm of opposition and highly emotional criticism, man was first conceived as a product of evolution rather than creation. Moreover, it is not yet thirty years since the chemical composition and molecular structure of the hereditary material was fully understood or the chromosome number of man became known. It should not be surprising then, to find how little, at present, we understand how our genes and chromosomes operate, and how they have evolved during phylogeny. In this work I have discussed how our own chromosomes have been transmitted and altered as far back as we may trace their phylogeny into the past. To make the work more complete, the composition and evolution of our own genome had also to be consiered in order to understand some of the recent findings at the chromosome level. These have resulted from using methods for localizing repetitive and single copy DNA sequences in chromosomes. Moreover, the development of biochemical methods of studying evolution at the macromolecular level has not only led to a more complete understanding of the evolutionary mechanisms, but has enabled us to make comparisons with evolutionary change at the chromosome level. In addition, a simple reference to the fossil record was necessary, because impressive discoveries in recent years have supplied valuable data on man's evolution.

This book was released on 2019-02-07 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Unbalanced Somatic Chromosomal Variation in Crepis The phenomenon of somatic chromosomal variation throws some light upon certain problems of general interest. Thus it is very prob able that occasional addition or subtraction of individual chromosomes may be responsible for bud variation of various kinds as has been suggested by various writers (cf. Review. By Chittenden, 1927 Balanced chromosomal variation may represent a legitimate condition of specialization of certain tissues. Somatic variation of high ire queney like that described above for C. Tectoru-m may result in chromo somal variegation. And, if genes of visible characters are involved in it, genetic variegation would be the result. In certain cases true somatic segregation may take place, namely, if one allelomorphic chromosome be replaced by another through the addition of one chromosome followed by the subtraction of another. Thus homozygous branches may eventually be produced by a heterozygous individual without. Any reverse gene mutation at all.
