Sex is the trait that determines whether a sexually reproducing animal or plant produces male or female gametes. Male plants and animals produce small mobile gametes, while females produce larger, non-motile ones. Organisms that produce both types of gametes are called hermaphrodites. During sexual reproduction, male and female gametes fuse to form zygotes, which develop into offspring that inherit traits from each parent.
Perspectivism is the epistemological principle that perception of and knowledge of something are always bound to the interpretive perspectives of those observing it. While perspectivism does not regard all perspectives and interpretations as being of equal truth or value, it holds that no one has access to an absolute view of the world cut off from perspective. Instead, all such viewing occurs from some point of view which in turn affects how things are perceived. Rather than attempt to determine truth by correspondence to things outside any perspective, perspectivism thus generally seeks to determine truth by comparing and evaluating perspectives among themselves. Perspectivism may be regarded as an early form of epistemological pluralism, though in some accounts includes treatment of value theory, moral psychology, and realist metaphysics.
In biology, gonochorism is a sexual system where there are only two sexes and each individual organism is either male or female. The term gonochorism is usually applied in animal species, the vast majority of which are gonochoric.
Isogamy is a form of sexual reproduction that involves gametes of the same morphology, found in most unicellular eukaryotes. Because both gametes look alike, they generally cannot be classified as male or female. Instead, organisms undergoing isogamy are said to have different mating types, most commonly noted as "+" and "−" strains.
Male is the sex of an organism that produces the gamete known as sperm, which fuses with the larger female gamete, or ovum, in the process of fertilization.
In cartography and geology, a topological map is a type of diagram that has been simplified so that only vital information remains and unnecessary detail has been removed. These maps lack scale, also distance and direction are subject to change and/or variation, but the topological relationship between points is maintained. A good example are the tube maps for the London Underground and the New York City Subway.

The Pyrenean desman also called Iberian desman is a small semiaquatic, globally threatened mammal related to moles and shrews, and, along with the Russian desman , is one of the two extant members of the tribe Desmanini. The species occurs in north and central parts of Spain and Portugal, French Pyrenees, and Andorra, but severe range contractions have been documented across its geographic distribution.
Santorio Santori also called Santorio Santorio, Santorio de' Sanctoriis, or Sanctorius of Padua and various combinations of these names, was an Italian physiologist, physician, and professor, who introduced the quantitative approach into the life sciences and is considered the father of modern quantitative experimentation in medicine.

The nominal fallacy, also known as the naming-explaining fallacy, is a logical fallacy in which it is incorrectly assumed that giving something a name is tantamount to explaining it. Stuart Firestein has described the fallacy as "...the error of believing that the label carries explanatory information." One example of the nominal fallacy is the use of the word "instinct" to explain a given behavior. Basically, asserting that "x" has a certain property just because of its name is another example of Nominal fallacy.

Simultaneous hermaphroditism is one of the two types of hermaphroditism, the other type being sequential hermaphroditism. In this form of hermaphroditism an individual has sex organs of both sexes and can produce both gamete types even in the same breeding season.
