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.

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.

Movement of transposable elements contributes to cichlid diversity

K. L. Carleton, M. Conte, M. Malinsky, S. P. Nandamuri, B. A. Sandkam, J. I. Meier, S. Mwaiko, O. Seehausen, T. D. Kocher

The paper identifies transposable element (TE)-induced indels as causative variants for visual sensitivity shifts in Lake Malawi cichlids, linking TE mobility to phenotypic diversity.

Tbx2a modulates switching of opsin gene expression

B. A. Sandkam, L. Campello, C. O'Brien, S. P. Nandamuri, W. Gammerdinger, M. Conte, A. Swaroop, K. L. Carleton

The paper identifies Tbx2a as a transcription factor that switches LWS and RH2 opsin expression in African cichlid fishes by promoting one while repressing the other.

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.
