The Vanishing Y Chromosome and the Future of Men
The Y chromosome is degenerating and may disappear in a few million years, leading to our extinction unless we evolve a new sex gene. A recent paper in Proceedings of the National Academy of Science shows how the spiny rat has evolved a new male-determining gene. The article also explains how the Y chromosome determines human sex and the disappearing Y chromosome in mammals.
Study Reveals Dynamics of Meiotic Recombination in Plants with Repeat-Based Holocentromeres
A recent study in Nature Plants explores the dynamics of crossover patterning in plants with repeat-based holocentromeres, focusing on the holocentric plant Rhynchospora breviuscula. The study reveals a distally biased crossover frequency, highlighting the primary influence of mechanistic features of meiotic pairing and synapsis rather than (epi)genomic features and centromere organization in determining the crossover distribution in this plant species.
