Inbreeding

Inbreeding Depression Inbreeding depression is a widely-studied topic in the fields of not only genetics, but as well as the fields of biology, ecology, etc. Directly speaking, inbreeding depression results in the loss or reduced expression of a trait due to the mating between two closely related organisms (Hartl 547). As of today, there are a plethora of studies and evidence that explain how and why inbreeding occurs within populations even though it is deleterious for the populations. However,

viruses, as well physical deformities. Several isolated population of cheetahs, which have experienced population bottleneck and high levels on inbreeding, as a result, are showing increased frequency of kinked tails and misaligned jaws, which reduce the feline’s hunting ability and therefore fitness. Other species that have shown signs of inbreeding after population bottleneck include the wolf populations in North America, giant pandas, as well as many wild feline populations. “A feral colony

Inbreeding is an extremely controversial topic of debate that has been around since biblical times. The most extreme form of inbreeding is incest, which is primarily between first cousins and second-first cousins.  Inbreeding is practiced for many different reasons including royalty, religion, culture, socioeconomic class, geographic isolation, and small populations. Possibly the most dramatic instance of incest for reasons of royalty was within Habsburg Dynasty. The Habsburg Dynasty was one of the

Review: In many small populations, inbreeding depression had created a major obstacle in the conservation of natural populations. To determine level of inbreeding in the Scandinavian wolf, Canis Lupus, DNA techniques were combined with the ecological field to construct the pedigree. This small population was founded by at least by two immigrated wolfs from a large Finnish/Russian source population. The field data was collected from the snow tracking and radio telemetry, and territorial pairs and

have a lower longevity and larger litter sizes. BMD had an especially lower life expectancy with a mean of 7.7 years and could be a consequence of histiocytic sarcoma that is prevalent within this breed of dog. This makes sense due to an effect of inbreeding being disease. There is a significant difference in life expectancy between big dog breeds such as in the BMD and GSD. For male GSD and BMD there are lower life expectancies in males. When considering mortality rates in sexes it is important to

To further investigate the inbreeding and its implications within royal families, studies have been conducted regarding the Habsburg royal dynasty of Spain, which came to an end after the demise of Charles II, a severely inbred individual. Charles II, known as “El Hechizado” (The Hexed) was a severely disabled man who suffered from mental retardation, learning difficulties and many health problems. He was short, he had a large head compared to his body size, he had blood in his urine, he had difficulties

By selectively breeding dogs for appearance, the gene pool of the different breeds is shrinking at an alarming rate. In the article, “Genetic diversity, inbreeding and breeding practices in dogs” by Leroy Grégoire, the topic of the genetic pool in dogs is discussed as an ill effect selective breeding has on it. The article tests the gene pool of dogs and comes to the conclusion of a decreasing trend in the data. Grégoire (2011) addressed the decrease of the gene pool in dogs by saying, “Since the

Alasdair, Wilkins. "Why Inbreeding Isn 't as Bad as You Think." Io9. Io9, 30 Dec. 2011. Web. 05 Feb. 2016.. In the article, “Why Inbreeding Isn’t as Bad as You Think”, Wilkins debunks the myths behind inbreeding and attributes them to cultural taboos. Wilkins alludes that cousins who are the first in their family lineage to inbreed have the exact same changes of having healthy offspring as unrelated couples. He then mentions that marrying a second cousin would greatly increase one 's chance of having

Inbreeding in the wild, and its effects, has been a largely contested subject over time. Not only has the occurrence of inbreeding depression in nature been questioned, but also the strength of it, that if it did occur if it was even worth noting. This has recently been explored within the literature both through field experiments as well as laboratory observations and model constructions. Not only has it been confirmed to occur in nature, but it has also been deemed of greater strength than previously
