Heterothallic species have sexes that reside in different individuals. The term is applied particularly to distinguish heterothallic fungi, which require two compatible partners to produce sexual spores, from homothallic ones, which are capable of sexual reproduction from a single organism.In heterothallic fungi, two different individuals contribute nuclei to form a zygote. Examples of heterothallism are included for Saccharomyces cerevisiae, Aspergillus fumigatus, Aspergillus flavus, Penicillium marneffei and Neurospora crassa. The heterothallic life cycle of N. crassa is given in some detail, since similar life cycles are present in other heterothallic fungi.

Heterotachy refers to shifts in site-specific evolutionary rates over time. In the field of molecular evolution, the principle of heterotachy states that the substitution rate of sites in a gene can change through time. It has been proposed that the positions that show switches in substitution rate over time (that is, heterotachous sites) are good indicators of functional divergence. However, it appears that heterotachy is a much more general process, since most variable sites of homologous proteins with no evidence of functional shift are heterotachous.The covarion hypothesis is a specific form of heterotachy. Some studies have proposed functional divergence models that are also heterotachous. Additionally, some mixture models that do not explicitly account for rate-shift, but site-partitions evolving at different relative substitution rates across lineages are mathematically heterotachous.Failure to take heterotachy into account in phylogenetic reconstructions may lead to incorrect phylogenetic trees. Thus Zhong et al. (2011) say that heterotachy is one of the reasons for variability in reconstructions of the origin of gnetophytes.

Heterotheca camporum, lemonyellow false goldenaster, is a North American species of flowering plant in the aster family. It is found only in the central United States, primarily the Ozarks, the Cumberland Plateau, and the middle Mississippi Valley. There are reports of additional populations in the Northeast, the Southeast, and in the Great Lakes region, but these appear to be waifs or naturalizations.Heterotheca camporum is a perennial herb growing 150 centimeters (5 feet) in height, spreading by means of underground rhizomes. There can be as many as 100 stems from one clone. Each stem can produce 1-24 flower heads in flat-topped arrays Each head contains 16–38 ray florets surrounding 23–66 tiny disc florets at the center.

The heterotrichs are a class of ciliates. They typically have a prominent adoral zone of membranelles circling the mouth, used in locomotion and feeding, and shorter cilia on the rest of the body. Many species are highly contractile, and are typically compressed or conical in form. These include some of the largest protozoa, such as Stentor and Spirostomum, as well as many brightly pigmented forms, such as certain Blepharisma.

In medicine, "heterotopia" refers to presence of a particular tissue type at a non-physiological site, but usually co-existing with original tissue in its correct anatomical location. In other words, it implies ectopic tissue, in addition to retention of the original tissue type. In neuropathology, for example, gray matter heterotopia, is the presence of gray matter within the cerebral white matter or ventricles.

The class Heterotardigrada includes tardigrades (water bears) that have cephalic appendages and legs with four separate but similar digits or claws on each. 444 species have been described.The anatomy of the reproductive system is an important defining feature in distinguishing the different groups of tardigrades. Heterotardigrades have gonoducts that open to the outside through a preanal gonopore, rather than opening into the rectum as in the only other confirmed class of tardigrades, the Eutardigrada (the third class, Mesotardigrada, is represented by a single species whose reference material was destroyed in an earthquake, so its reproductive anatomy has not been studied recently).Some orders of heterotardigrades are marine, others are terrestrial, but as for all tardigrades, all are aquatic in the sense that they must be surrounded by at least a film of moisture in order to be active - though they can survive in a dormant state if the habitat dries out.

Synaptic plasticity refers to a chemical synapse's ability to undergo changes in strength. Synaptic plasticity is typically input-specific (i.e. homosynaptic plasticity), meaning that the activity in a particular neuron alters the efficacy of a synaptic connection between that neuron and its target. However, in the case of heterosynaptic plasticity, the activity of a particular neuron leads to input unspecific changes in the strength of synaptic connections from other unactivated neurons.

However, in the case of heterosynaptic plasticity, the activity of a particular neuron leads to input unspecific changes in the strength of synaptic connections from other unactivated neurons. A number of distinct forms of heterosynaptic plasticity have been found in a variety of brain regions and organisms. These different forms of heterosynaptic plasticity contribute to a variety of neural processes including associative learning, the development of neural circuits, and homeostasis of synaptic input.

Heterotheca grandiflora is a species of flowering plant in the daisy family known by the common name Silk-grass goldenasteror telegraphweed. It is native to the southwestern United States (California, Nevada, Utah, Arizona) and northwestern Mexico (Baja California), but it can be found in other areas as an introduced species, such as Hawaii. It is often a roadside weed even where it is native.Heterotheca grandiflora is a tall, bristly, glandular plant exceeding a meter (40 inches) in height and densely foliated in hairy to spiny toothed or lobed leaves. Leaves are smaller and more widely spaced toward the top of the stem, which is occupied by an inflorescence of bright yellow daisy-like flower heads. The disc and ray florets drop away to leave a spherical head of achenes, each with a long white pappus.

Heterosuchus is an extinct genus of crocodylomorph that may have been an eusuchian. It is known only from neck and back vertebrae recovered from Early Cretaceous-age rocks of the Hastings Beds (Wealden Group of Hastings, Sussex. These vertebrae are procoelous (ball-and-socket articulation with the socket in front and the ball on the back of individual vertebrae), which is a trait of eusuchians. Heterosuchus was described by Harry Seeley in 1887, with H. valdensis as the type species. It may be the same genus as the slightly younger Hylaeochampsa, inferred to have been of similar evolutionary grade, but there is no overlapping material as Hylaeochampsa is known only from a partial skull; Hylaeochampsa would be the name used for both in that case, because it is the older name (coined in 1874). Because of the sparse material and apparent lack of distinguishing characteristics, James Clark and Mark Norell (1992) considered Heterosuchus a dubious name.

Heterotaxis sessilis is an epiphytic orchid widespread across the West Indies (Cuba, Hispaniola, Jamaica, Trinidad), Central America (all 7 countries), southern Mexico (Chiapas, Veracruz, Oaxaca, Quintana Roo), Florida and northern South America (Colombia, Ecuador, Peru, northern Brazil, Venezuela, the Guianas). Hidden orchid is a common name.The species was long called by the synonym Maxillaria crassifolia but recent molecular studies have indicated that Maxillaria should be split into several genera.

Heterotheca shevockii is a rare species of flowering plant in the aster family known by the common names Kern Canyon false goldenaster and Shevock's goldenaster. It is endemic to California in the United States, where it is known only from Kern County. It grows along a 21-mile stretch of the Kern River.Heterotheca shevockii is a perennial herb growing 28 to 131 centimeters (11.2-52.4 inches) in height, often with many erect stems. The stems are hairy to bristly. The lance-shaped leaves are up to 6.5 centimeters (2.6 inches) long by 1.6 cm (0.64 inches) wide. The inflorescence contains 3-70 flower heads borne on hairy, glandular peduncles. Each head contains up to 18 yellow ray florets each up to a centimeter long, and many disc florets at the center. The fruit is an achene which may be over a centimeter (>0.4 inches) long including its pappus. Flowering occurs mostly in August and September, but it may be seen in flower between January and November.Heterotheca shevockii grows in chaparral and woodland habitat in sandy soils in crevices and ditches near the river. There are about 8 known populations of this plant, totalling 246 individuals.

In medicine, "heterotopia" refers to presence of a particular tissue type at a non-physiological site, but usually co-existing with original tissue in its correct anatomical location. In other words, it implies ectopic tissue, in addition to retention of the original tissue type. In neuropathology, for example, gray matter heterotopia, is the presence of gray matter within the cerebral white matter or ventricles. Heterotopia within the brain is often divided into three groups: subependymal heterotopia, focal cortical heterotopia and band heterotopia. Another example is a Meckel's diverticulum which may contain heterotopic gastric or pancreatic tissue.In biology specifically, heterotopy refers to an altered location of trait expression. In her landmark book,Developmental Plasticity and Evolution Mary-Jane West Eberhard has a provocative cover art of the Sulphur Crested Cockatoo and comments on the back cover "Did it's long crest[head] feathers evolve by gradual modification of ancestral head feathers? Or are they descendants of wing feathers, developmentally transplanted onto the head" This idea sets the tone for the rest of her book which goes into depth about developmental novelties and their relation to evolution. Heterotopy is a somewhat obscure but well demonstrated example of how developmental change can lead to novel forms. The central concept is that a feature seen in one area of an organism has had its location changed in evolutionary lineages.
