The evolution of sex chromosomes influences reproductive biology and genome evolution across species. In Drosophila pseudoobscura, the Y chromosome has a distinct origin compared to Drosophila ...

Conventional wisdom holds that sexual reproduction evolved because it enables organisms to shuffle, or recombine, different alleles (versions of a gene) in the next generation, producing the genetic ...

Comparison of over 200 high-quality butterfly and moth genomes reveals key insights into their biology, evolution and diversification Cookie settings over the last 250 million years, as well as clues ...

Sex is determined in a variety of different ways throughout the animal kingdom. In mammals, it is determined genetically, not by temperature, as it can be in reptiles. Typically, females have two X ...
