Sex chromosomes of birds as reservoir for jumping genes

Occurring in the genomes of most living organisms, transposable elements (TEs) are short DNA sequences that have the ability change their position. By means of various molecular mechanisms—so-called copy-paste or cut-and-paste—they ...

How to maintain gender equality through the sex chromosomes

Asymmetric sex chromosomes were independently shaped during evolution in many species, and different strategies evolved alongside to overcome the resulting imbalance in genetic information. Molecular biologist Marie-Line ...

Gene-editing used to create single sex mice litters

Scientists at the Francis Crick Institute, in collaboration with University of Kent, have used gene editing technology to create female-only and male-only mice litters with 100% efficiency.
