- n. Plural form of parthenogen.
Sorry, no etymologies found.
Some of the nuts which I am calling parthenogens have developed plants this year.
The same pattern pops up a number of times in harvestmen - Caddo agilis, Caddo pepperella and (if I recall correctly) Crosbycus dasycnemus are all individual species that each show this kind of distribution (mind you, they're also all mostly parthenogens, so morphological conservatism may be hiding genetic diversity).
It was difficult to be sure of securing reliable pollen and of getting it to the flowers at the right time and surely, so that we would have good hybrids instead of parthenogens which sometimes develop as the result of the female not making fusion with its mate.
The trees have not borne as yet and we can not tell if they are true hybrids or parthenogens.
They show the Siebold parentage so distinctly that I imagine them to be parthenogens, but we cannot tell to a certainty until they bear fruit.
Chromosomes in the parthenogens are therefore unpaired, and for many of them the parental species have been worked out this way.
Genetic analysis confirmed that they were parthenogens.
