Breeding Line
Breeding is sexual reproduction that produces offspring, usually animals or plants. It can only occur between a male and a female animal or plant. Breeding may refer to: * Animal husbandry, through selected specimens such as dogs, horses, and rabbits * Breeding in the wild, the natural process of reproduction in the animal kingdom * Sexual reproduction of plants * Plant breeding, through specimens selected by humans for desirable traits Science * Breeding refers to nuclear transmutations that produce fuel for further reactions, in a breeder reactor to become fissile material or in a fusion reactor to produce tritium, see Biology * Breeding (sex act) * Breeding back, a breeding effort to re-assemble extinct breed genes * Breeding pair, bonded animals who cooperate to produce offspring * Breeding program, a planned breeding of animals or plants * Breeding season, the period during each year when a species reproduces * Captive breeding, raising plants or animals in zoos or ot ...

Sexual Reproduction
Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete ( haploid reproductive cells, such as a sperm or egg cell) with a single set of chromosomes combines with another gamete to produce a zygote that develops into an organism composed of cells with two sets of chromosomes ( diploid). This is typical in animals, though the number of chromosome sets and how that number changes in sexual reproduction varies, especially among plants, fungi, and other eukaryotes. Sexual reproduction is the most common life cycle in multicellular eukaryotes, such as animals, fungi and plants. Sexual reproduction also occurs in some unicellular eukaryotes. Sexual reproduction does not occur in prokaryotes, unicellular organisms without cell nuclei, such bacteria and archaea. However, some process in bacteria may be considered analogous to sexual reproduction in that they incorporate new genetic information, including bacterial conjugation, transformatio ...

Selective Breeding
Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together. Domesticated animals are known as breeds, normally bred by a professional breeder, while domesticated plants are known as varieties, cultigens, cultivars, or breeds. Two purebred animals of different breeds produce a crossbreed, and crossbred plants are called hybrids. Flowers, vegetables and fruit-trees may be bred by amateurs and commercial or non-commercial professionals: major crops are usually the provenance of the professionals. In animal breeding, techniques such as inbreeding, linebreeding, and outcrossing are utilized. In plant breeding, similar methods are used. Charles Darwin discussed how selective breeding had been successful in producing change over time in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manners
Etiquette () is the set of norms of personal behaviour in polite society, usually occurring in the form of an ethical code of the expected and accepted social behaviours that accord with the conventions and norms observed and practised by a society, a social class, or a social group. In modern English usage, the French word ' (label and tag) dates from the year 1750. History In the third millennium BCE, the Ancient Egyptian vizier Ptahhotep wrote ''The Maxims of Ptahhotep'' (2375–2350 BC), a didactic book of precepts extolling civil virtues, such as truthfulness, self-control, and kindness towards other people. Recurrent thematic motifs in the maxims include learning by listening to other people, being mindful of the imperfection of human knowledge, and that avoiding open conflict, whenever possible, should not be considered weakness. That the pursuit of justice should be foremost, yet acknowledged that, in human affairs, the command of a god ultimately prevails in ...

Inbreeding
Inbreeding is the production of offspring from the mating or breeding of individuals or organisms that are closely related genetically. By analogy, the term is used in human reproduction, but more commonly refers to the genetic disorders and other consequences that may arise from expression of deleterious or recessive traits resulting from incestuous sexual relationships and consanguinity. Animals avoid incest only rarely. Inbreeding results in homozygosity, which can increase the chances of offspring being affected by recessive traits. In extreme cases, this usually leads to at least temporarily decreased biological fitness of a population (called inbreeding depression), which is its ability to survive and reproduce. An individual who inherits such deleterious traits is colloquially referred to as ''inbred''. The avoidance of expression of such deleterious recessive alleles caused by inbreeding, via inbreeding avoidance mechanisms, is the main selective reason for outcrossin ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Copulation (zoology)
In zoology, copulation is animal sexual behavior in which a male introduces sperm into the female's body, especially directly into her reproductive tract. This is an aspect of mating. Many animals that live in water use external fertilization, whereas internal fertilization may have developed from a need to maintain gametes in a liquid medium in the Late Ordovician epoch. Internal fertilization with many vertebrates (such as all reptiles, some fish, and most bird Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweig ...s) occurs via cloacal copulation, known as cloacal kiss (see also hemipenis), while mammals copulate vaginally, and many primitive (biology), basal vertebrates reproduce sexually with external fertilization.

Dust Breeding
''Dust Breeding'' is a Big Finish Productions audio drama based on the long-running British science fiction television series ''Doctor Who''. The story marks the return of Caroline John to ''Doctor Who'' and the introduction of the Master to the Big Finish continuity. Plot The Seventh Doctor's diary has a strange entry that the painting "The Scream" by Edvard Munch is going to be destroyed in "mysterious circumstances". So he and Ace visit a colony of artists on the barren dust world of Duchamp 331 to find out more. He isn't expecting the return of one of his most personal enemies...

Breeding The Spawn
''Breeding the Spawn'' is the second full-length album by Suffocation. Though it still employs the characteristics and elements associated with Suffocation's song writing, the production on the album is much thinner than on other albums, due to financial problems regarding their label Roadrunner Records. However it shows a more complex and technical side of the band. Most likely to make up for the relatively poor production on the album, tracks from ''Breeding the Spawn'' were re-recorded for inclusion on five Suffocation albums to date: "Breeding the Spawn" on ''Pierced from Within''; "Prelude to Repulsion" and "Anomalistic Offerings" on ''Suffocation'' (the latter found on the Japanese version of the album); "Marital Decimation" on '' Blood Oath''; "Beginning of Sorrow" on ''Pinnacle of Bedlam'' and "Epitaph of the Credulous" on '' ...Of the Dark Light''.
