Evidence that genetic drift not adaptation drives fast‐Z and large‐Z effects in Ficedula flycatchers

open access: yesMolecular Ecology, EarlyView.
Abstract The sex chromosomes have been hypothesized to play a key role in driving adaptation and speciation across many taxa. The reason for this is thought to be the hemizygosity of the heteromorphic part of sex chromosomes in the heterogametic sex, which exposes recessive mutations to natural and sexual selection. The exposure of recessive beneficial

Hybridization and gene expression: Beyond differentially expressed genes

open access: yesMolecular Ecology, EarlyView.
Abstract Gene expression has a key role in reproductive isolation, and studies of hybrid gene expression have identified mechanisms causing hybrid sterility. Here, we review the evidence for altered gene expression following hybridization and outline the mechanisms shown to contribute to altered gene expression in hybrids. Transgressive gene expression,

How admixed captive breeding populations could be rescued using local ancestry information

open access: yesMolecular Ecology, EarlyView.
Abstract This paper asks the question: can genomic information be used to recover a species that is already on the pathway to extinction due to genetic swamping from a related and more numerous population? We show that a breeding strategy in a captive breeding program can use whole genome sequencing to identify and remove segments of DNA introgressed ...
