Results for “reproduction”

reproduction

Production of offspring via a sexual or asexual process.

Used in 111 profiles

asexual reproduction

Mode of reproduction which does not involve fertilisation whereby offspring derive from a single parent and inherit genes only from that parent. Known in the Amazon Molly, Poecilia formosa, and some other fish species.

reproductive isolation

The inability of two or more groups of organisms to interbreed due to the existence of geographical, behavioral, physiological, or genetic barriers. These can be further separated into those being active pre- or post-copulation.

allopatric

Occurring in separate, nonoverlapping geographic areas. Often used to refer to geographically-separated, reproductively-isolated populations of related organisms. Opposite of sympatric.

Used in 2 profiles

monogamy

The practice or state of having only one reproductive partner over a given period of time, e.g., a single breeding season, year, or entire reproductive life.

abdomen

The lower part of the body that lies in front of the cloaca and contains the digestive and reproductive organs; also referred to as the belly.

allelopathy

A biological phenomenon by which an organism produces one or more biochemicals that affect the growth, survival, and reproduction of others. Typical in certain plants, algae, bacteria, coral, and fungi.

amphibian

A class of cold-blooded vertebrates, generally requiring water for reproduction.

aplacental viviparity

Also known as ovoviviparity. Method of reproduction employed by certain fishes in which the eggs are fertilised and develop inside the female but there is no placental connection. The juveniles are free-swimming and able to feed as soon as they leave the female's body.

biological species concept

Most popular concept of species in vertebrate zoology. Defines species as members of populations that do or potentially could interbreed and produce fertile offspring in nature, regardless of appearance, therefore somewhat more restrictive than the phylogenetic species concept. In theory species are thus separated from one another by some form of reproductive isolation, though in practice this does not always hold true. Often abbreviated to BSC.

cavity brooder

Reproductive strategy characteristic of certain fishes, e.g., many cichlids, in which eggs in a cavity, cave or similar. The clutch is normally guarded aggressively by one or both parents. Such species may also be referred to as 'cave brooders/breeders'.

clone

Specimen descended from and genetically identical to a single common ancestor with natural examples normally resulting from asexual reproductive events. Produced via parthenogenesis in some fishes.

dioecious

Within a species, having the male and female reproductive organs in separate individuals.

fertile

Capable of reproduction.

Used in 11 profiles

gamete

Cell that fuses with another during fertilization in organisms employing sexual reproduction, e.g., an egg or sperm cell.

genital

Of or relating to the genitals or the process of biological reproduction.

Used in 74 profiles

genital papilla

Small tube arising from the urogenital opening in some fishes through which male or female gametes are expelled. May only be visible during the reproductive period depending on taxon. Its shape can sometimes used as a feature to identify the gender of an individual.

Used in 114 profiles

genitalia

The reproductive organs, especially used in reference to external sex organs.

hermaphrodite

Animal or plant possessing both male and female reproductive organs.

intromittent

Used in reference to a modified fin of a male which aids in transfer of gametes to the female during reproduction.
