- The modulation of DNA content: proximate causes and ultimate consequencesT R Gregory
Department of Zoology, University of Guelph, Guelph, Ontario N1G 2W1
Genome Res 9:317-24. 1999..These abrupt shifts have broad effects on phenotypic attributes at both cellular and organismal levels and may play an important role in explaining episodes of rapid-or even saltational-character state evolution...
- Evolutionary implications of the relationship between genome size and body size in flatworms and copepodsT R Gregory
Department of Zoology, University of Guelph, Guelph, Ontario, Canada N1G 2W1
Heredity (Edinb) 84:201-8. 2000..Genome sizes appear to vary in a discontinuous fashion among congeneric species in both groups, indicating that such changes have occurred rapidly, and with potentially profound effects on important morphological characters...
- Nucleotypic effects without nuclei: genome size and erythrocyte size in mammalsT R Gregory
Department of Zoology, University of Guelph, ON, Canada
Genome 43:895-901. 2000..In evolutionary terms, they provide insights into the constraints on genome expansion among mammals and are therefore of interest in attempts to solve the long-standing C-value enigma (also known as the C-value paradox)...
- The bigger the C-value, the larger the cell: genome size and red blood cell size in vertebratesT R Gregory
Department of Zoology, University of Guelph, Guelph, Ontario N1G 2W1, Canada
Blood Cells Mol Dis 27:830-43. 2001..The present article describes the correlation between genome size and RBC size in vertebrates and discusses some of the cytological, physiological, and evolutionary implications of this relationship...
- Coincidence, coevolution, or causation? DNA content, cell size, and the C-value enigmaT R Gregory
Department of Zoology, University of Guelph, Ontario, Canada
Biol Rev Camb Philos Soc 76:65-101. 2001..Finally, some evolutionary implications of genome size diversity are considered, and a broadening of the traditional 'biological hierarchy' is recommended...
- An expansion of the genome size dataset for the insect order Hymenoptera, with a first test of parasitism and eusociality as possible constraintsA M Ardila-Garcia
Department of Integrative Biology, University of Guelph, Guelph, ON, Canada
Insect Mol Biol 19:337-46. 2010..The data provided here can be used to guide future research aimed at understanding the evolution of large-scale genomic properties in this order...
- Genome size diversity in the family DrosophilidaeT R Gregory
Department of Integrative Biology, University of Guelph, Guelph, Ontario, Canada
Heredity (Edinb) 101:228-38. 2008..These findings may provide some explanation for the streamlined genomes found in these insects, and complement recent work demonstrating possible selective constraints on further deletion of noncoding DNA...
- Genome sizes of spidersT R Gregory
Department of Zoology, University of Guelph, Guelph, ON N1G 2W1 Canada
J Hered 94:285-90. 2003..No clear-cut patterns of variation were detectable even with this relatively large data set, but some interesting avenues for future research have been illuminated by this preliminary survey...
