A revised infrageneric classification of Crepis, maintaining 21 of Babcock's 27 sections, some in a revised circumscription, is provided; in addition, C. sect. Calliopea is re-established and C. Bruhin () reports that treatment of Crepis capillaris seeds at 45OC for 16 to 20 days consistently increases the spontaneous mutation rate in this species. METABOLISM AND SPONTANEOUS MUTATIONS IN PLANTS 7 Zeu mays. Chlorophyll defects and a few morphological mutations were reported by Pet0 () t o occur in maize plants raised from aged Cited by: Sinnott and Dunn's Principles of Genetics has long been a standard text on genetics. The third edition was reviewed in Plant Breeding Abstracts, Vol. IX, p. In this, the fourth edition, Professor Dobzhansky appears as a third author and the entire text is said to have been rewritten to incorporate recent developments. The main additions to the text are concerned with nuclear division and Cited by:
B chromosomes are widely distributed among eukaryotes. Table summarizes the number of species in which B chromosomes have been found to date in different taxa. It shows that B chromosomes have been reported in 10 species of fungi, nearly plants (more than when different ploidy levels of the same species are considered separately), and well over animals.

These supernumeraries were somatically stable, heterochromatic and had sub-median centromeres. At metaphase I they were about half the size of the smallest euchromatic chromosomes. 2. At diakinesis and metaphase I, the supernumeraries formed bivalents and multivalents in moderately Cited by: The return of many genes back to single copy with disomic chromosomal inheritance and, in some cases, to smaller genome size and reduced chromosome numbers can occur through diploidization.
The development of what became known as the biological species concept began with a paper by Theodosius Dobzhansky in , and was amplified by a mutualistic interaction between Dobzhansky, Alfred Emerson and Ernst Mayr after the second world war.

These characters enable discrimination between hips of R. rugosa and R. canina (L.) Crépin, even when the tissue has been pulverized. The achene micromorphology was described by Jessen (), Starikova (), Grigas () and Anderberg ().
