| heterochromatin, facultative | Heterochromatin that need not always be heterochromatic but has the faculty to return to the normal euchromatic state. The inactive x chromosome is made up of facultatative heterochromatin. When a woman transmits that x to a son, it reverts to euchromatin and genetic activity. (12 Dec 1998) |

| facultative | Of parasites, optional. Compare: obligate. (09 Oct 1997) |
| facultative aerobe | <microbiology> An organism which is normally anaerobic but can also grow in the presence or oxygen. (15 Nov 1997) |
| facultative anaerobe | <microbiology> A microorganism which can survive without oxygen (is an anaerobe) but is not harmed if oxygen is present. (09 Oct 1997) |
| facultative heterochromatin | <cell biology> The heterochromatin which is condensed in some cells and not in others, presumably representing stable differences in the activity of genes in different cells. The best known example results from the random inactivation of one of the pair of X chromosomes in the cells of female mammals, (Lyonisation). (18 Nov 1997) |
| facultative hyperopia | Hyperopia that can be compensated by accommodation. Synonym: facultative hyperopia. (05 Mar 2000) |
| facultative parasite | An organism that may either lead an independent existence or live as a parasite, in contrast to obligate parasite. (05 Mar 2000) |
| facultative ponds | Ponds having an aerobic zone on the top and an anaerobic zone on the bottom. (05 Dec 1998) |
| facultative species | <ecology> Species that can occur both in wetlands and uplands, there are three subcategories of facultative species: 1. Facultative wetland plants (FACW) that usually occur in wetlands (estimated probability 67-99%), but occasionally are found in nonwetlands. 2. Facultative plants (FAC) that are equally likely to occur in wetlands or nonwetlands (estimated probability 34-66%). 3. Facultative upland plants (FACU) that usually occur in nonwetlands (estimated probability 67-99%), but occasionally are found in wetlands (estimated probability (1-33%). (09 Oct 1997) |
| allogeneic inhibition | Inhibition or injury to allogeneic cells that occurs when lymphocytes are mixed and cultured with other cells of different genotypes in vitro. (05 Mar 2000) |
| macrophage inhibition factor | <cytokine> A group of lymphokines (including a 14 kD glycoprotein) produced by activated T lymphocytes that reduces macrophage mobility and probably increases macrophage macrophage adhesion. (18 Nov 1997) |
| macrophage migration inhibition test | A test which measures the presence of migration-inhibitory factor. Usually peritoneal macrophages are placed in a capillary tube in the presence or absence of supernatants from activated T-cells. If MIF is present, the migration of monocyte/macrophages is reduced. Synonym: macrophage migration inhibition test, migration inhibition test. (05 Mar 2000) |
| reactive inhibition | Tendency toward a lessened strength of response due to practice or activity. It is independent of the effect of reward and is a direct function of time interval since the last response and the number of preceding responses. (12 Dec 1998) |
| reciprocal inhibition | Contraction in a muscle is accompanied by a loss of tone or by relaxation in the antagonistic muscle. Synonym: reciprocal inhibition. (05 Mar 2000) |
| reflex inhibition | A situation in which sensory stimuli decrease reflex activity. (05 Mar 2000) |
