A high school student uses crowdfunding to produce the first genome assembly for this popular aquarium species, underscoring the increasing feasibility of whole-genome sequencing.
Parents’ mutations, even if they’re not inherited by offspring, could affect subsequent generations through changes to epigenetic marks, a study finds.
Evidence is mounting that epigenetic marks on DNA can influence future generations in a variety of ways. But how such phenomena might affect large-scale evolutionary processes is hotly debated.
Trofim Lysenko’s attacks on geneticists had long-term effects on Russian science and scientists, despite a lack of evidence to support his beliefs about biological inheritance.
In the 20th century, animals such as mules and ligers that had parents of different species were considered biological flukes, but genetic sequencing is beginning to unravel the critical role of hybridization in evolution.
