  • Exactly what the difference is between linebreeding and inbreeding tends to be defined differently for each species and often for each breed within the species. (mcf.com)
  • Phys.org) -Mating with relatives, or inbreeding, can be costly to both sexes, and in many species males and females avoid mating with siblings. (phys.org)

  • siblings

  • Nearly
  • Nearly thirty gray wolves living on an island chain in northwestern Lake Superior have backbone malformations as a result of genetic inbreeding, presenting yet another hurdle for the wolves' long-term survival, wildlife experts say. (redorbit.com)
  • genes
  • Inbreeding can thus bring these undesirable recessive genes to the surface, where they can be removed from the breeding pool. (mcf.com)
  • It is easier and faster to lose genes (sometimes very desirable genes) from the breeding pool when inbreeding is practiced than when a more open breeding system is used. (mcf.com)
  • Basically, the problem with inbreeding is that it increases the risk that both male and female have the same unfavorable genes and this again increases the risk that the chicks will display these genes. (backyardchickens.com)
  • it is thought to reduce the possibility of new ideas coming in from outside sources, just as genetic inbreeding reduces the possibility of new genes entering into a population. (wikipedia.org)
  • traits
  • Inbreeding (i.e., breeding between closely related individuals) results in more recessive traits manifesting themselves, as the genomes of pair-mates are more similar. (wikipedia.org)
  • this very uniformity means that fewer individuals are required to produce results with the same level of statistical significance when an inbred line is used in comparison to an outbred line in the same experiment Breeding of inbred strains is often towards specific phenotypes of interest such as behavioural traits like alcohol preference or physical traits like aging. (wikipedia.org)
  • practice
  • Intellectual inbreeding or academic inbreeding is the practice in academia of a university's hiring its own graduates to be professors. (wikipedia.org)
  • Academic inbreeding has also been cited as a major problem in the major universities of the People's Republic of China-such as Peking University and Tsinghua University, which have adopted measures in recent years specifically to combat the practice-and South Korea. (wikipedia.org)
  • Definition
  • Since all pure breeds of animal trace back to a relatively limited number of foundation dogs, all pure breeding is by this definition inbreeding, although the term is not generally used to refer to matings where a common ancestor does not occur behind sire and dam in a four or five generation pedigree. (mcf.com)

  • The Copenhagen Zoo went ahead with a plan to shoot and dismember a healthy giraffe on Sunday and feed the 18-month-old animal's carcass to lions - an action the zoo said was in line with anti-inbreeding rules meant to ensure a healthy giraffe population. (yahoo.com)
  • In general, the higher the genetic variation or gene pool within a breeding population, the less likely it is to suffer from inbreeding depression. (wikipedia.org)
  • This generally leads to a decreased fitness of a population, which is called inbreeding depression. (phys.org)
  • Inbreeding results in inbreeding depression, which is the reduction of fitness of a given population due to inbreeding. (wikipedia.org)
  • When heterozygotes possess a fitness advantage relative to a homozygote, a population with a large number of homozygotes will have a relatively reduced fitness, thus leading to inbreeding depression. (wikipedia.org)

  • avoid
  • Early humans who lived around 34,000 years ago recognised the dangers of inbreeding and developed social and mating networks to avoid it, new research has found. (sooperarticles.com)
  • The results suggest that people deliberately sought partners beyond their immediate family, and that they were probably connected to a wider network of groups within which mates were chosen, in order to avoid becoming inbred. (sooperarticles.com)
