High-resolution sex-specific linkage maps of the mouse reveal polarized distribution of crossovers in male germline.

abstract：:Though much has been learned about the process of ovarian follicle maturation through studies of oogenesis in both vertebrate and invertebrate systems, less is known about how follicles form initially. In Drosophila, two somatic follicle stem cells (FSCs) in each ovariole give rise to all polar cells, stalk cells, and...
