Mating preferences of selfish sex chromosomes

P Muralidhar - Nature, 2019 - nature.com
The evolution of female mating preferences for harmful male traits is a central paradox of
sexual selection 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 – 9 . Two dominant explanations for this paradox 8 , 10 …

Changes in selection pressure can facilitate hybridization during biological invasion in a Cuban lizard

…, SN Michaelides, P Muralidhar… - Proceedings of the …, 2021 - National Acad Sciences
Hybridization is among the evolutionary mechanisms most frequently hypothesized to drive
the success of invasive species, in part because hybrids are common in invasive populations…

Drift-induced selection between male and female heterogamety

C Veller, P Muralidhar, GWA Constable, MA Nowak - Genetics, 2017 - academic.oup.com
Evolutionary transitions between male and female heterogamety are common in both
vertebrates and invertebrates. Theoretical studies of these transitions have found that, when all …

Sexual antagonism and the instability of environmental sex determination

P Muralidhar, C Veller - Nature ecology & evolution, 2018 - nature.com
The sex of an organism can be determined by its genetics or its early environment. Across the
animal kingdom, genetic sex determination (GSD) is far more common than environmental …

Assortative mating enhances postzygotic barriers to gene flow via ancestry bundling

P Muralidhar, G Coop, C Veller - Proceedings of the …, 2022 - National Acad Sciences
Hybridization and subsequent genetic introgression are now known to be common features
of the histories of many species, including our own. Following hybridization, selection often …

Recombination and selection against introgressed DNA

C Veller, NB Edelman, P Muralidhar, MA Nowak - BioRxiv, 2019 - biorxiv.org
DNA introgressed from one species into another is typically deleterious at many genomic
loci in the recipient species. It is therefore purged by selection over time. Here, we use …

Recombination and selection against introgressed DNA

C Veller, NB Edelman, P Muralidhar, MA Nowak - Evolution, 2023 - academic.oup.com
Introgressed DNA is often deleterious at many loci in the recipient species’ genome, and is
therefore purged by selection. Here, we use mathematical modeling and whole-genome …

Dominance shifts increase the likelihood of soft selective sweeps

P Muralidhar, C Veller - Evolution, 2022 - academic.oup.com
Genetic models of adaptation to a new environment have typically assumed that the alleles
involved maintain a constant fitness dominance across the old and new environments. …

Polygenic response of sex chromosomes to sexual antagonism

P Muralidhar, G Coop - Evolution, 2024 - academic.oup.com
Sexual antagonism occurs when males and females differ in their phenotypic fitness optima
but are constrained in their evolution to these optima because of their shared genome. The …

Variation in genetic relatedness is determined by the aggregate recombination process

C Veller, NB Edelman, P Muralidhar, MA Nowak - Genetics, 2020 - academic.oup.com
The genomic proportion that two relatives share identically by descent—their genetic
relatedness—can vary depending on the history of recombination and segregation in their pedigree…
