Genetic Selection: Definition, Pros & Cons When it comes to the genetic traits of a population, 'selection' is the process that chooses those traits. Artificial genetic selection is controversial, especially when it comes to human beings. This lesson defines genetic selection and discusses the pros and cons of artificial genetic selection.

- Parents choose a mate for their offspring based on certain characteristics, usually involving financial security, however, rather than genetic traits. Examples: Perhaps the best known use of artificial selection is dog breeding. The American Kennel Club (AKC) recognizes over 700 different breeds of dogs.

Artificial Intelligence (AI) Artificial intelligence (AI) is an area of computer science that emphasizes the creation of intelligent machines that work and react like humans. Some of the activities computers with artificial intelligence are designed for include: Speech recognition.

Who was King Arthur's half-sister? Answer by Plucas. Confidence votes 31.4K. Later legends say that Arthur had three half-sisters: Morgawse, Elaine (Blasine) and Morgan le Fay. Morgawse had married King Lot of Orkney, Elaine (Blasine) was married to King Nentres of Garlot, while Morgan was wife of King Urien of Gorre, brother of Lot.

Artificial insemination Artificial insemination. Artificial insemination (AI) is the deliberate introduction of sperm into a female's uterus or cervix for the purpose of achieving a pregnancy through in vivo fertilization by means other than sexual intercourse. It is a fertility treatment for humans, and is common practice in animal breeding, including dairy cattle (see Frozen bovine semen) and pigs.

Chapter 13- Evolution The theory of its action was first fully expounded by Charles Darwin and is now believed to be the main process that brings about evolution artificial selection The selective breeding of domesticated plants and animals to encourage the occurrence of desirable traits.

Natural selection Mechanism of evolution by differential survival and reproduction of individuals For other uses, see natural selection. Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. Charles Darwin popularised the term natural selection, contrasting it with artificial selection, which is intentional, whereas natural selection is

Sex selection This article is about the artificial selection of the sex of offspring. For the evolutionary concept, see sexual selection. Sex selection is the attempt to control the sex of the offspring to achieve a desired sex. It can be accomplished in several ways, both pre- and post-implantation of an embryo, as well as at childbirth. It has been marketed under the title family balancing.

Natural selection The term was introduced by Darwin in his influential 1859 book On the Origin of Species, in which natural selection was described as analogous to artificial selection, a process by which animals and plants with traits considered desirable by human breeders are systematically favored for reproduction.

Stabilizing selection Stabilizing selection (not to be confused with negative or purifying selection[1][2]) is a type of natural selection in which the population mean stabilizes on a particular non-extreme trait value.

- Artificial gene synthesis is a method in synthetic biology that is used to create artificial genes in the laboratory.urrent gene synthesis approaches are most often based on a combination of organic chemistry and molecular biological techniques and entire genes may be synthesized de novo, without the need for precursor template DNA.

natural selection natural selection. The principle that only organisms best suited to their environment survive long enough to pass on their genetic characteristics to their offspring. According to this principle, the proportion of the species having these characteristics increases with each generation. Natural selection results from random variation of genetic traits in a species and forms the basis of the process of evolution. See Notes at adaptation, evolution.

- There is no simple answer to this question. Intersex con-ditions are not always accurately diagnosed, expertssometimes disagree on exactly what qualifies as an inter-sex condition, and government agencies do not collectstatistics about intersex individuals.

Artificial Intelligence (AI) Artificial intelligence is a branch of computer science that aims to create intelligent machines. It has become an essential part of the technology industry. Research associated with artificial intelligence is highly technical and specialized. Knowledge engineering is a core part of AI research.

- Natural selection and selective breeding can both cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene. For this reason selective breeding is sometimes called artificial selection.

Natural selection Natural selection is the differential survival and reproduction of individuals due to differences in phenotype; it is a key mechanism of evolution.actors that affect reproductive success are also important, an issue that Darwin developed in his ideas on sexual selection, which was redefined as being included in natural selection in the 1930s when biologists considered it not to be very important, and fecundity selection, for example.

Selective breeding New varieties. Natural selection and selective breeding can both cause changes in animals and plants. The difference between the two is that natural selection happens naturally, but selective breeding only occurs when humans intervene. For this reason selective breeding is sometimes called artificial selection.

What is the Purpose of Natural selection? The concept of natural selection was originally developed in the absence of a valid theory of heredity; at the time of Darwin's writing, nothing was known of modern genetics. The union of traditional Darwinian evolution with subsequent discoveries in classical and molecular genetics is termed the modern evolutionary synthesis.

Selection bias The phrase selection bias most often refers to the distortion of a statistical analysis, resulting from the method of collecting samples. If the selection bias is not taken into account, then some conclusions of the study may not be accurate.

- Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in heritable traits of a population over time. Charles Darwin popularised the term natural selection; he compared it with artificial selection (selective breeding). Variation exists within all populations of organisms.

Darwin (där'wĭn) British naturalist who proposed the theory of evolution based on natural selection (1858). Darwin's theory, that random variation of traits within an individual species can lead to the development of new species, revolutionized the study of biology.
