What life forms have no male or female genders?

Question

SCIENTIC NAMES PLEASE , THANK YOU.

Answer 1

Hermaphroditism habitually occurs in many invertebrate animals, in the hagfish and tunicate, and in the sea bass of the genus Serranus. It occurs occasionally in other fishes, in frogs, toads, and certain newts among the amphibians. Hermaphrodite animals are rarely self-fertilizing; in most cases the spermatozoa and ova mature at different times (successive hermaphroditism), or the male and female external organs are located so that self-fertilization is impossible. Among the invertebrates, sponges, cnidarians, some mollusks, and earthworms are regularly hermaphroditic. Flatworms have a complete set of male and female gonads in each segment and regularly fertilize themselves.

True functional hermaphroditism is rare or absent in higher animals. One occasionally sees animals called hermaphrodites that appear intermediate in form between males and females, but such animals are usually sterile, and, when fertile, do not produce both fertile eggs and fertile sperm. Such organisms are often called intersexes or sex-intergrades; intersexes in the fruit fly have been shown to arise from inheritance of an abnormal ratio of male Y chromosomes to female X chromosomes (see Genetics). Human pseudohermaphrodites show functional disturbance of the endocrine glands, especially of the pituitary or adrenal glands, and do not possess two sets of functioning sex organs. Because of the homology between male and female sex organs, it may be difficult to tell whether a human hermaphrodite is a female with overdeveloped clitoris or a male with underdeveloped penis, cleft scrotum, and nondescendant testes. Recently, many persons have undergone surgical or hormone treatment to modify their nonfunctioning sex characteristics and emphasize the sex indicated by those that are functional.
