Two sexes, one genome: the evolutionary dynamics of intralocus sexual conflict

TM Pennell, EH Morrow - Ecology and evolution, 2013 - Wiley Online Library
As the evolutionary interests of males and females are frequently divergent, a trait value that
is optimal for the fitness of one sex is often not optimal for the other. A shared genome also …

[HTML][HTML] Genome-wide sexually antagonistic variants reveal long-standing constraints on sexual dimorphism in fruit flies

F Ruzicka, MS Hill, TM Pennell, I Flis, FC Ingleby… - PLoS …, 2019 - journals.plos.org
The evolution of sexual dimorphism is constrained by a shared genome, leading to ‘sexual
antagonism’, in which different alleles at given loci are favoured by selection in males and …

Contrasting effects of intralocus sexual conflict on sexually antagonistic coevolution

TM Pennell, FJH de Haas… - Proceedings of the …, 2016 - National Acad Sciences
Evolutionary conflict between the sexes can induce arms races in which males evolve traits
that are detrimental to the fitness of their female partners, and vice versa. This interlocus …

Building a new research framework for social evolution: intralocus caste antagonism

TM Pennell, L Holman, EH Morrow… - Biological Reviews, 2018 - Wiley Online Library
Pennell). Although they are morphologically similar, the co-foundresses will later display
different behavioural phenotypes, with one female dominating most of the reproduction and the …

The condition‐dependence of male genital size and shape

TM Pennell, MD Sharma, A Sutter… - Ecology and …, 2024 - Wiley Online Library
The male genitals of internal fertilisers evolve rapidly and divergently, and sexual selection
is generally responsible for this. Many sexually selected traits are condition‐dependent—with …

[HTML][HTML] Whole genome resequencing of a laboratory-adapted Drosophila melanogaster population sample

WP Gilks, TM Pennell, I Flis, MT Webster… - …, 2016 - ncbi.nlm.nih.gov
As part of a study into the molecular genetics of sexually dimorphic complex traits, we used
high-throughput sequencing to obtain data on genomic variation in an outbred laboratory-…

[HTML][HTML] Split sex ratios and genetic relatedness in a primitively eusocial sweat bee

TM Pennell, J Field - Behavioral Ecology and Sociobiology, 2021 - Springer
In eusocial Hymenoptera, queens and their helper offspring should favour different sex
investment ratios. Queens should prefer a 1:1 investment ratio, as they are equally related to …

Sex-biased gene expression in Drosophila melanogaster is constrained by ontogeny and genetic architecture

FC Ingleby, CL Webster, TM Pennell, I Flis, EH Morrow - bioRxiv, 2016 - biorxiv.org
Sexual dimorphism is predicted to be constrained by the underlying genetic architecture
shared between the sexes and through ontogeny, but whole-transcriptome data for both sexes …

Cardiovascular magnetic resonance

DJ Pennell - Circulation, 2010 - Am Heart Assoc
Cardiovascular magnetic resonance (CMR) creates images from atomic nuclei with uneven
spin using radiowaves in the presence of a magnetic field. Full details of the physical …
