Extensive variation in germline de novo mutations in Poecilia reticulata

Y. Lin, I. Darolti, W. van der Bijl, J. Morris, J. E. Mank

This study quantifies de novo mutations in guppies, finding substantial individual and family variation in germline mutation rates and evidence of shared mutations across siblings.

Functional convergence of genomic and transcriptomic genetic architecture underlying sociability in a live-bearing fish

A. Corral-Lopez, N. I. Bloch, W. van der Bijl, M. Cortazar-Chinarro, A. Szorkovszky, A. Kotrschal, I. Darolti, S. D. Buechel, M. Romenskyy, N. Kolm, J. E. Mank

The paper investigates the genetic basis of sociability in guppies using quantitative genetics and transcriptomics, finding convergent genomic and transcriptomic signatures related to synaptic function and calcium signaling.

Experience with mating receptivity cues affects sexual behaviour of male guppies, but not their strength of preference towards receptive females

V. Goberdhan, I. Darolti, W. van der Bijl, J. E. Mank, A. Corral-Lopez

The study shows that male guppies with experience of female receptivity cues adapt their mating tactics but do not show stronger preference for receptive females.

Sex-biased gene expression at single-cell resolution: Cause and consequence of sexual dimorphism

I. Darolti, J. E. Mank

This study uses single-cell RNA-seq to analyze sex-biased gene expression in guppies, showing how cell type abundance differences can confound sex bias patterns and affect evolutionary analysis.

Sex Chromosome Heteromorphism and the Fast-X Effect in Poeciliids

I. Darolti, L. Fong, B. A. Sandkam, D. C. H. Metzger, J. E. Mank

This study investigates Fast-X evolution in Poeciliid fish by analyzing sequence divergence and polymorphism across species with varying sex chromosome heteromorphism.

GENE DUPLICATION TO THE Y CHROMOSOME IN TRINIDADIAN GUPPIES

Y. Lin, I. Darolti, B. L. S. Furman, P. Almeida, B. A. Sandkam, F. Breden, A. E. Wright, J. E. Mank

The paper identifies gene duplications to the Y chromosome in guppies, suggesting it resolves sexual conflict over survival rather than unresolved conflict.

Rapid evolution of complete dosage compensation in Poecilia

D. C. Metzger, B. A. Sandkam, I. Darolti, J. E. Mank

The paper identifies rapid evolution of complete dosage compensation in Poecilia species, supporting theoretical predictions about the parallel evolution of dosage compensation with sex chromosome divergence.

HIGH-RESOLUTION CHARACTERIZATION OF MALE ORNAMENTATION AND REEVALUATION OF SEX LINKAGE IN GUPPIES

J. Morris, I. Darolti, W. van der Bijl, J. E. Mank

This study reevaluates Y-linkage in guppy male ornamentation using automated image analysis, finding that individual ornaments are not predominantly Y-linked but modifier loci affecting overall coloration may be.

Divergence and Remarkable Diversity of the Y Chromosome in Guppies

P. Almeida, B. A. Sandkam, J. Morris, I. Darolti, F. Breden, J. E. Mank

This study examines Y chromosome divergence and diversity in guppies, finding that recombination suppression occurs through gradual mechanisms rather than inversions, and that haplotype diversity is linked to female preference for rare color variations.

Extreme heterogeneity in sex chromosome differentiation and dosage compensation in livebearers

I. Darolti, A. E. Wright, B. A. Sandkam, J. Morris, N. I. Bloch, M. Farre, R. C. Fuller, G. R. Bourne, D. M. Larkin, F. Breden, J. E. Mank

The paper analyzes sex chromosome differentiation and dosage compensation in livebearing fish, finding extreme variation across species and a novel neo-sex chromosome in P. picta.
