| nonMendelian inheritance | <genetics> In eukaryotes, patterns of gene transmission not explicable in terms of segregation, independent assortment and linkage. May be due to cytoplasmic inheritance, gene conversion, meiotic drive, etc. (18 Nov 1997) |

| inheritance | 1. The act or state of inheriting; as, the inheritance of an estate; the inheritance of mental or physical qualities. 2. That which is or may be inherited; that which is derived by an heir from an ancestor or other person; a heritage; a possession which passes by descent. "When the man dies, let the inheritance Descend unto the daughter." (Shak) 3. A permanent or valuable possession or blessing, especially. One received by gift or without purchase; a benefaction. "To an inheritance incorruptible, and undefiled, and that fadeth not away." (1 Pet. I. 4) 4. Possession; ownership; acquisition. "The inheritance of their loves." "To you th' inheritance belongs by right Of brother's praise; to you eke longs his love." (Spenser) 5. <biology> Transmission and reception by animal or plant generation. 6. A perpetual or continuing right which a man and his heirs have to an estate; an estate which a man has by descent as heir to another, or which he may transmit to another as his heir; an estate derived from an ancestor to an heir in course of law. The word inheritance (used simply) is mostly confined to the title to land and tenements by a descent. "Men are not proprietors of what they have, merely for themselves; their children have a title to part of it which comes to be wholly theirs when death has put an end to their parents' use of it; and this we call inheritance." (Locke) Origin: Cf. OF. Enheritance. Source: Websters Dictionary (01 Mar 1998) |
| extrachromosomal inheritance | Transmission of hereditary characters by non-chromosomal replicating cytoplasmic structures such as mitochondria, plastids, and plasmids. (12 Dec 1998) |
| extranuclear inheritance | <genetics> Inheritance of parental characters through a nonchromosomal means, thus mitochondrial DNA is cytoplasmically inherited since the information is not segregated at mitosis. In a broader sense the organisation of a cell may be inherited through the continuity of structures from one generation to the next. It has often been speculated that the information for some structures may not be encoded in the genomic DNA, particularly in protozoa that have complex patterns of surface organelles. See: maternal inheritance. (18 Nov 1997) |
| uniparental inheritance | <genetics> A type of inheritance in which the offspring of a mating has the phenotype (observable physical traits) of only one parent. (09 Oct 1997) |
| pili, sex | Filamentous or elongated proteinaceous structures which extend from the cell surface in gram-negative bacteria that contain certain types of conjugative plasmid. These pili are the organs associated with genetic transfer and have essential roles in conjugation. Normally, only one or a few pili occur on a given donor cell. this preferred use of "pili" refers to the sexual appendage, to be distinguished from bacterial fimbriae (fimbriae, bacterial), also known as common pili, which are usually concerned with adhesion. (12 Dec 1998) |
| primary sex characters | The sex glands, testes or ovaries, and the accessory sex organs. (05 Mar 2000) |
| safe sex | Sexual practices that limit the risk of transmitting or acquiring an infectious disease via exchanges of semen, blood, and other bodily fluids, e.g., use of a condom, mutual masturbation, and avoidance of anal intercourse. (05 Mar 2000) |
| heterogametic sex | <biology> The gender which has two different sex chromosomes. For example: In humans, the male is heterogametic because he is XY (has an X chromosome and a Y chromosome). In birds, the female is heterogametic because she is WZ (has a W chromosome and a Z chromosome). Compare: homogametic sex. (09 Oct 1997) |
| secondary sex characters | Those character's peculiar to the male or female that develop at puberty, e.g., the beard of men and the breasts of women. (05 Mar 2000) |
| homogametic sex | <genetics> The gender which has two copies of the same sex chromosome. For example: In humans, the female is homogametic because she is XX (has two copies of the X chromosome). In birds, the male is homogametic because he is ZZ (has two copies of the Z chromosome). Compare: heterogametic sex. (09 Oct 1997) |
| sex | 1. The distinguishing peculiarity of male or female in both animals and plants; the physical difference between male and female; the assemblage of properties or qualities by which male is distinguished from female. 2. One of the two divisions of organic beings formed on the distinction of male and female. 3. <botany> The capability in plants of fertilizing or of being fertilized; as, staminate and pistillate flowers are of opposite sexes. One of the groups founded on this distinction. The sex, the female sex; women, in general. Origin: L. Sexus: cf. F. Sexe. Source: Websters Dictionary (01 Mar 1998) |
