Sex Chromosome Evolution in Muscid Flies

Rapd-pcr Based Genetic Relationship of Muscid Flies

Random Amplified Polymorphic DNA-Polymerase Chain Reaction (RAPD-PCR) technique has been used in the present study to investigate genetic relationship between the two muscids viz., housefly Musca domestica Linnaeus and Lispe orientalis (Wiedemann). Tools for Population Genetic Analysis (TFPGA) software, was used to calculate genetic identity and distance, using data matrix prepared by the prese...

Sex-specific adaptation drives early sex chromosome evolution in Drosophila.

Most species' sex chromosomes are derived from ancient autosomes and show few signatures of their origins. We studied the sex chromosomes of Drosophila miranda, where a neo-Y chromosome originated only approximately 1 million years ago. Whole-genome and transcriptome analysis reveals massive degeneration of the neo-Y, that male-beneficial genes on the neo-Y are more likely to undergo accelerate...

Genetic conflict and sex chromosome evolution.

Chromosomal sex determination systems create the opportunity for the evolution of selfish genetic elements that increase the transmission of one sex chromosome at the expense of its homolog. Because such selfish elements on sex chromosomes can reduce fertility and distort the sex ratio of progeny, unlinked suppressors are expected to evolve, bringing different regions of the genome into conflic...

Molecular Analysis of Medically and Veterinary Important Muscid Flies (Diptera: Muscidae) in Thailand

We demonstrated the using of the internal transcribed spacer (ITS2) of ribosomal DNA as a tool for identification of medically and veterinary important Muscidae flies in Thailand. A total of 27 fly samples were collected from various regions of Thailand. Six fly species in three subfamilies including Azeliinae (Hydrotaea spinigera), Muscinae (Musca domestica, M. sorbens) and Stomoxyinae (Stomox...
