Nels and Vincent explore a direct experimental test of Ohno’s Hypothesis, which states that gene duplication can help genes tolerate new mutations and thus facilitates the evolution of new phenotypes.
Nels and Vincent discuss how duplication of a gene encoding a transcription factor led to evolution of a novel cell type in the slime mold Dictyostelium.
Nels and Vincent discuss signatures of sex chromosome evolution revealed by assembly of a young vertebrate Y chromosome from 3-spined stickleback fish.
