AF-vapeR: A multivariate genome scan for detecting parallel evolution using allele frequency change vectors

J. R. Whiting, J. R. Paris, M. van der Zee, B. A. Fraser

AF-vapeR detects parallel evolution by analyzing allele frequency change vectors across populations, identifying regions with correlated genetic changes and reducing false negatives.

A large and diverse autosomal haplotype is associated with sex-linked colour polymorphism in the guppy

J. R. Paris, J. R. Whiting, M. J. Daniel, J. Ferrer Obiol, P. J. Parsons, M. J. van der Zee, C. W. Wheat, K. A. Hughes, B. A. Fraser

The paper identifies a large autosomal haplotype associated with sex-linked color polymorphism in guppies, challenging the traditional view of color genes being on the sex chromosome.

On the genetic architecture of rapidly adapting and convergent life history traits in guppies

J. R. Whiting, J. R. Paris, P. J. Parsons, S. Matthews, Y. Reynoso, K. A. Hughes, D. Reznick, B. A. Fraser

This study investigates the genetic architecture of life history traits in guppies, finding polygenic traits underlie rapid adaptation but may limit genetic convergence across populations.

Rapid genomic convergent evolution in experimental populations of Trinidadian guppies (Poecilia reticulata)

M. J. van der Zee, J. R. Whiting, J. R. Paris, R. D. Bassar, J. Travis, D. Weigel, D. N. Reznick, B. A. Fraser

This study identifies candidate loci for convergent evolution in guppies adapted to low predation environments using genome-wide sequencing and a novel multivariate approach.

Drainage-structuring of ancestral variation and a common functional pathway shape limited genomic convergence in natural high- and low-predation guppies

J. R. Whiting, J. R. Paris, M. J. van der Zee, P. J. Parsons, D. Weigel, B. A. Fraser

The paper examines genomic convergence in guppies across different drainages, finding limited shared adaptive variation but repeated selection on cadherin signaling pathways and a common haplotype.

Improved reference genome uncovers novel sex-linked regions in the guppy (Poecilia reticulata)

B. A. Fraser, J. R. Whiting, J. R. Paris, C. J. Weadick, P. J. Parsons, D. Charlesworth, R. Bergero, F. Bemm, M. Hoffmann, V. A. Kottler, C. Liu, C. Dreyer, D. Weigel

The paper presents an improved guppy reference genome using long-read sequencing, revealing novel sex-linked regions and resolving previous contradictions in Y chromosome studies.

Contingent Convergence: The ability to detect convergent genomic evolution is dependent on population size and migration

J. R. Whiting, B. A. Fraser

This study shows that demographic factors like population size and migration can create false-positive signals in genetic outlier scans used to detect convergent evolution.
