Huddling: Brown Fat, Genomic Imprinting and the Warm Inner Glow
(Elsevier, 2008)
Heat generated by huddling animals is a public good with a private cost and thus vulnerable to exploitation, as illustrated by recent work on rabbits and penguins. Effects of imprinted genes on brown adipose tissue suggest ...
Placental Growth Hormone-Related Proteins and Prolactin-Related Proteins
(Elsevier, 2008)
The placentas of ruminants and muroid rodents express prolactin (PRL)-related genes whereas the placentas of anthropoid primates express growth hormone (GH)-related genes. The evolution of placental expression is associated ...
Parental sex discrimination and intralocus sexual conflict
(The Royal Society, 2009)
Intralocus sexual conflict occurs when populations segregate for alleles with opposing fitness consequences in the two sexes. This form of selection is known to be capable of maintaining genetic and fitness variation in ...
Sexual Antagonism and the Evolution of X Chromosome Inactivation
(Wiley Blackwell (Blackwell Publishing), 2008)
In most female mammals, one of the two X chromosomes is inactivated early in embryogenesis. Expression of most genes on this chromosome is shut down, and the inactive state is maintained throughout life in all somatic ...
Flt1, pregnancy, and malaria: Evolution of a complex interaction
(Proceedings of the National Academy of Sciences, 2008)
Kinship Asymmetries and the Divided Self
(Cambridge University Press, 2008)
Imprinted genes are predicted to affect interactions among relatives. Therefore, variant alleles at imprinted loci are promising candidates for playing a causal role in disorders of social behavior. The effects of imprinted ...
Homologous Versus Antithetic Alternation of Generations and the Origin of Sporophytes
(Springer-Verlag, 2008)
The late-nineteenth/early-twentieth century debate over homologous versus antithetic alternation of generations is reviewed. Supporters of both theories, at first, used Coleochaete as a model for the origin of land-plant ...
Reciprocally Imprinted Genes and the Response to Selection on One Sex
(The Genetics Society of America, 2008)
We explore the theoretical consequences of limiting selection to males for the evolution of imprinted genes. We find that the efficiency of male-limited selection depends on the pattern of imprinting at an imprinted locus. ...
Divergent Mating Systems and Parental Conflict as a Barrier to Hybridization in Flowering Plants
(University of Chicago Press, 2005)
Parental conflicts can lead to antagonistic coevolution of the sexes and of parental genomes. Within a population, the resulting antagonistic effects should balance, but crosses between populations can reveal conflict. ...
Maintenance or Loss of Genetic Variation Under Sexual and Parental Antagonism at a Sex-Linked Locus
(Wiley-Blackwell, 2009)
An intralocus genetic conflict occurs when a locus is selected in opposing directions in different subsets of a population. Populations with two sexes have the potential to host a pair of distinct intralocus conflicts: ...
