(n.) An individual which has the attributes of both male and female, or which unites in itself the two sexes; an animal or plant having the parts of generation of both sexes, as when a flower contains both the stamens and pistil within the same calyx, or on the same receptacle. In some cases reproduction may take place without the union of the distinct individuals. In the animal kingdom true hermaphrodites are found only among the invertebrates. See Illust. in Appendix, under Helminths.

(15) Furthermore, the germ-line specificity of the fem-3(gf) mutant phenotype and the late temperature-sensitive period suggest that, in the wild-type XX hermaphrodite, fem-3 is negatively regulated so that the hermaphrodite stops making sperm and starts making oocytes.
(16) An unusual case of hermaphroditism in a 4 to 5-year-old roe is described.
(17) and Grassi Milano observed that when the female gonads were cultured without steroid or gonadotrophic hormones at the start of differentiation an hermaphrodite left ovary and a male right one were formed.
(18) Loss-of-function mutations in the spe-11 gene in Caenorhabditis elegans result in a paternal-effect embryonic-lethal phenotype: fertilization of wild-type oocytes by sperm from homozygous spe-11 mutant males leads to abnormal zygotic development, whereas oocytes from homozygous spe-11 hermaphrodites when fertilized by wild-type sperm develop normally.
(19) In wild-type Caenorhabditis elegans there are two sexes, self-fertilizing hermaphrodites (XX) and males (XO).
(20) Six out of 22 can transform XO animals into fertile females or hermaphrodites, whereas the remainder cause partial feminization.
Monoecious
Definition:
(a.) Having the sexes united in one individual, as when male and female flowers grow upon the same individual plant; hermaphrodite; -- opposed to dioecious.
Example Sentences:
(1) The equivalent monoecious fitnesses must be calculated by weighting each sex by the number of genes carried by an individual at the locus under consideration.
(2) A very general partial differential equation in space and time satisfied by the gene frequency in a monoecious population distributed continuously over an arbitrary habitat is derived.
(3) A continuous time selection model is formulated for a diploid monoecious population with multiple alleles at each of an arbitrary number of loci, incorporating differential fertility and mortality as well as arbitrary mating and age structure.
(4) Results are obtained for populations in drift and mutation balance, for infinite populations undergoing mixed self and random mating, and for finite monoecious populations with or without selfing.
(5) The above results apply to autosomal loci in monoecious (with or without selfing) and dioecious populations and to X-linked loci.
(6) Some stochastic theory is developed for monoecious populations of size N in which there are probabilities beta and 1 - beta of reproduction by selfing and by random mating.
