In the field of biology, artificial selection covers a whole host of subtopics. One can implement artificial selection to eradicate disease, increase yield per acre, lower competition within an ecosystem, or produce a new color in a breed of dog. With recent strides in the uncovering of the genetic sequences of a long list of organisms, it is possi...
Unnatural selection, or artificial selection, is the result of human action. In the case of the abovementioned fainting goats, myotonia congenita would almost certainly lead to the mutation’s extinction should the animals involved live in the wild. This extinction would be the result of natural selection, as any predatorattack would render the muta...
Artificial selection is used to improve the health and well-being of the global population or to improve the health and well-being of an individual. However, the benefit or disadvantage of other factors pertaining to the results of artificial selection is often forgotten. Agricultural ecosystems featuring pest- and mold-resistant crops will, in pri...
Artificial selection is an evolutionary process in which humans consciously select for or against particular features in organisms – for example, by choosing which individuals to save seeds from or breed from one generation to the next.
Artificial selection is a powerful technique for investigating the heritability and underlying genetic architecture of traits, as well as for searching for potential physiological factors underlying the evolutionary shifts in traits (Gibbs, 1999; Rose et al., 1992; Bennett and Lenski, 1999; Bradley et al., 1999; Harshman and Hoffmann, 2000 ...
Feb 28, 2021 · Artificial selection (also known as selective breeding) 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.
2 days ago · The selection response is dependent on two factors—the narrow-sense heritability and the selection differential, S. The selection differential is a measure of the average superiority of individuals selected to be parents of the next generation. R = h2S (5.4.1) (5.4.1) R = h 2 S. The above equation is often called the “breeder’s equation”.
May 16, 2020 · Artificial selection is the process by which natural variations that are advantageous from the perspective of humans are selected unnaturally or artificially. Charles Darwin discussed the concepts of artificial selection as domestication in his classic monograph On the Origin of Species by Means of Natural Selecti on in 1859 (Darwin 1859).
