📝 英文原版摘要

Proceedings of the National Academy of Sciences, Volume 123, Issue 9, March 2026. <br />SignificanceMale moths and butterflies produce two different sperm types: one with DNA that fertilizes eggs (eupyrene), and one without DNA (apyrene), which facilitates fertilization. We use microscopy and RNA sequencing to study how these two sperm ...
