Single cell RNA sequencing of D. pseudoobscura testes reveals transcriptional signatures of heteromorphic spermatogenesis

Sperm heteromorphy, the production of multiple sperm morphs with distinct functions, has evolved repeatedly in animals but its developmental and molecular basis remains poorly understood. In the Drosophila obscura group, males produce fertilising eusperm and non-fertilising parasperm, yet when and how these lineages di...
