In its native Argentina, about half the plants are hermaphrodite and about half are female, but the hermaphrodite plants apparently don't put much effort into producing seeds.In other words, hermaphrodites are effectively male and thus pampas grass is effectively dioecious.The hermaphrodite germ line produces both male and female gametes—sperm and oocytes, respectively (see Germline Section in Worm Book). Oocytes are produced throughout adult life; sperm (spermatozoa) are generated during L4 and then used in adulthood to fertilize oocytes.

Pampas grass (Cortaderia selloana) is more complicated.These findings also apply to animals (via the unified theory) and provide the first evidence in support of the theory that the establishment of separate sexes stemmed from a genetic mutation in hermaphroditic genes that led to male and female sex chromosomes.With the ability to breed but spared the inbred defects of hermaphrodites, the separate sexes flourished.“This is an important test of the theory of the early stages of sex chromosome evolution and part of the process of understanding the way we are today,” Ashman said.This content is available through Read Online (Free) program, which relies on page scans.Since scans are not currently available to screen readers, please contact JSTOR User Support for access.
