The phorid fly Megaselia scalaris is a laboratory model for the turnover and early differentiation of sex chromosomes. Isolates from the field have an XY sex-determining mechanism with chromosome pair 2 acting as X and Y chromosomes. The sex chromosomes are homomorphic but display early signs of sex chromosome differentiation: a low level of molecular differences between X and Y. The male-determining function (M), maps to the distal part of the Y chromosome’s short arm. In laboratory cultures… Expand
Reversal of an ancient sex chromosome to an autosome in Drosophila
TLDR
The results reveal several puzzling aspects of Drosophila dot chromosome biology to be possible remnants of its former life as a sex chromosome, such as its minor feminizing role in sex determination or its targeting by a chromosome-specific regulatory mechanism. Expand
Determining the size of the male-specific region in the genome of the scuttle fly, Megaselia scalaris, a potential model system for the earliest stages of sex chromosome evolution
TLDR
This study refined the boundaries within which the sex realizer (M) of M. scalaris may be located, and found the M. Scalaris genome to be 27% male-specific, a preliminary result suggesting a large size inconsistent with published reports. Expand
How Big Is Your Y? A Genome Sequence-Based Estimate of the Size of the Male-Specific Region in Megaselia scalaris
TLDR
Next-generation sequencing data from a newly obtained natural isolate of M. scalaris shows that even highly conservative estimates for the size of the male-specific genome are likely too large to be contained within a transposable element, suggesting transposition of themale-determining region either is extremely rare or has not persisted recently in natural populations, allowing for differentiation of the sex chromosomes of this species.

Sex Chromosome Evolution: Birth, Maturation, Decay, and Rebirth
TLDR
This chapter discusses sex chromosomes, which originate from autosomes through gain of a sex-determining function and undergo a series of evolutionary transitions including association with sexually antagonistic genes, suppression of recombination, genomic degeneration as a result of mutation accumulation, and inactivation and loss of genes. Expand
Numerous Transitions of Sex Chromosomes in Diptera
Many species groups, including mammals and many insects, determine sex using heteromorphic sex chromosomes. Diptera flies, which include the model Drosophila melanogaster, generally have XY sexExpand
Sex determination strategies in 2012: towards a common regulatory model?
TLDR
This review summarizes current evidence from research in this hot field and signifies the need for further study of both normal hormonal regulators of sexual phenotype and patterns of environmental disruption. Expand
Sex chromosome evolution in moths and butterflies
TLDR
The Z chromosomes are highly conserved among Lepidoptera, much like the Z in birds or the X in mammals, but the W chromosome, which is present in most lepidopteran species, was incorporated in the sex chromosome system much later, about 90–100 MY ago. Expand
Inexorable spread: inexorable death? The fate of neo-XY chromosomes of grasshoppers
TLDR
Although neo-XY chromosomes of grasshoppers maybe a useful model to explain the spread of a new chromo-somal rearrangement, they are not a predictive example of sex-chromosome evolution and recycling. Expand
Heterochronic shifts in germband movements contribute to the rapid embryonic development of the coffin fly Megaselia scalaris.
TLDR
Comparison of stages between D. melanogaster and both Megaselia species reveals that heterochronic shifts, simultaneous morphogenetic movements and compression of individual stages all contribute to the rapid development of M. scalaris embryogenesis. Expand
Evolutionary interaction between W/Y chromosome and transposable elements
TLDR
Based on the review of the most recent publications, knowledge on W/Y evolution in relation to retrotransposable element accumulation is presented. Expand

Sex determination in the fly Megaselia scalaris, a model system for primary steps of sex chromosome evolution.
TLDR
With Megaselia, the flyMegaselia scalaris Loew is afforded an experimental system to study the otherwise hypothetical primary stages of sex chromosome evolution, and an initial molecular differentiation is apparent even in the new sex chromosomes. Expand
An X/Y DNA segment from an early stage of sex chromosome differentiation in the fly Megaselia scalaris.
TLDR
The sex chromosomes of the Megaselia scalaris wild-type strain Wien are homomorphic, and a roughly 1.8 kb X/Y DNA segment of this strain includes the first part of a coding sequence for a protein of the vespid antigen 5 family. Expand
The sex-determining region of theMegaselia scalaris (Diptera) Y chromosome
TLDR
To define the sex-determining region of the Except42 Y chromosome, cosmid clones were isolated and used as probes for chromosomalin situ suppression (CISS) hybridization, which map the conserved Y segment, including the male-d determining factor, to the distal segment of the short arm of the Y chromosome. Expand
Sequence conservation and expression of the sex-lethal homologue in the fly Megaselia scalaris.
TLDR
A non-sex-determining function during early embryogenesis is suggested; the presence of Megsxl RNA in testes and somatic tissues calls for other (or more) functions. Expand
Expression of the sex determining cascade genes Sex-lethal and doublesex in the phorid fly Megaselia scalaris.
TLDR
The results suggest that the sex-determining pathway of M. scalaris joins that of D. melanogaster between the Sxl and dsx steps, and that SxL does not exist in somatic tissues of adult females and males. Expand

Musca domestica, a window on the evolution of sex-determining mechanisms in insects.
TLDR
In the house fly, Sex-lethal is not involved in sex determination, and dosage compensation, if existent at all, is not coupled with sexual differentiation, which allows for more adaptive plasticity in the housefly system. Expand
Steps in the evolution of heteromorphic sex chromosomes
TLDR
Evidence that recombination suppression occurs progressively in evolutionarily independent cases is reviewed, suggesting that selection drives loss of recombination over increasingly large regions. Expand
Inheritance of cytogenetic and new genetic markers in Megasella scalaris, a fly with an unusual sex determining mechanism
TLDR
Seven cytogenetic markers, translocations T1–T7, and three new genetic markers, ge, By and sh, were isolated and characterized during this study, and are intended to serve as a framework to fit in molecular markers. Expand
Molecular differentiation of the homomorphic sex chromosomes inMegaselia scalaris (Diptera) detected by random DNA probes
TLDR
It was concluded that the Y chromosome contains a conserved segment in which crossover is suppressed and restriction site differences have accumulated relative to the X, which conform to a theoretically expected early stage of sex chromosome evolution. Expand
