Inbreeding

Inbreeding in captive populations of animals also occurs, and is generally done intentionally for various reasons. Animals can become inbred as a result of selective breeding for desirable traits. Animals in captivity face different selection pressures in comparison to those in the wild, as they are provided with optimal environmental conditions and have the natural ability to choose a mate removed. Breeding solely within a single captive population of animals eliminates the addition of different alleles to the gene pool and reduces the genetic diversity of the population. This means that the probability of genetic material being more uniform is more common in a captive population and so inbreeding depression is more likely to occur. Inbreeding is likely to occur on commercial farms as a by-product of selective breeding. As many of the animals will possess the alleles for the same desirable traits to maximise yield and profit, these animals will be bred and this can have a negative impact on animal welfare. For example, dairy cattle can be bred for maximum milk production, and even though this increases profit for a farmer, it has adverse effects on the cow, leaving…

Introduction The purpose of my research paper was to define and expand on what animal inbreeding and selective breeding is in the Herpetology world. I have provided definitions of both along with the pros and cons as well. Once done, I hope you will have a clear understanding of the uniqueness of each along with the positive and negative aspects of both topics. Both topics are allowed to be very objective, subjective, or opinionated; however, in the end, inbreeding and selective breeding…

OBJECTIVES 1) To study how pumas recognize kin and the general mechanisms of inbreeding avoidance in a non-threatened population and to address how this information might inform studies in threatened populations. 2) To measure the link between population size and inbreeding rates in puma concolor in the 4 Southern California locations. 3) To identify whether the kin recognition mechanism is faulty in Southern California population, and if they had to genetically change in order to allow…

tigers and lions are very pretty animals, but how they were created is not so pretty. These animals were caused by inbreeding; they are a man made creature created by a specific change in the DNA strands creating things like an organism lacking pigment in the skin. Inbred animals also have a higher chance of gaining genetic disorders that can majorly harm them, there are many things that inbreeding can do to an animals from how they look to how their brains function. Inbreeding is all because of…

DNA determines how our body functions and what we look like. So what is the reason that could cause our own DNA to be our downfall? Inbreeding, which is the mating of organisms that are relatives. Inbreeding or the breeding or related individuals will cause an issue known as inbreeding depression. This is when the biological fitness in a population is reduced. Zoos take part in the practice of inbreeding because they take the claim that it is for the repopulation of the species close to…

Reserve genetics is a tool used to identify the functionality of a known gene sequence or a gene family by genetic editing to generate the mutant phenotype. As it is done in a direction from gene to phenotype, which is opposite to ‘forward genetics’, hence named as reverse genetics. As the whole genome sequences are much more accessible nowadays with various genome sequencing technologies developed. This enables modifying a known gene, and to create a known mutation. The mutated gene might then…

Boakes, E. H., J. Wang, and W. Amos. "An Investigation Of Inbreeding Depression And Purging In Captive Pedigreed Populations." Heredity 98.3 (2007): 172-182. Academic Search Premier. Web. 5 July 2015. The purpose of this is to show that the inbreeding in zoos is hurting populations of animals in zoos rather than helping them. The type of person that would read this article is someone interested in the breeding practices of zoos. Inbreeding has proven to weaken the immune system and breeding…

Inbreeding: It is something that we feel, as a society, we have moved entirely away from, and yet it still haunts and evokes a deep fear within us that something so sinister could have happened among us. Edgar Allen Poe, in his work the Fall of the House of Usher, brings the sinister consequences of inbreeding front and center, yet he still manages to do it quite subtly. One of many themes, inbreeding is key to fully understanding the plot and the deeper messages of the Fall of the House of…

Edgar Allen Poe, in his work “The Fall of the House of Usher”, brings the sinister consequences of inbreeding front and center, in a way that informs, yet entertains, the reader. One of many themes, inbreeding is key to fully understanding the plot and messages of ‘The Fall of the House of Usher” and fully engaging with the text. Poe is able to enter into scientific discourse and discuss both the physical and psychological penalties of inbreeding by making sinister implications about Roderick…

successful due to its long term effects of increased inbreeding of individuals and decline in population size. Genetic rescue events are important since they help to preserve the survival of species. Humans are necessary to assist with gene flow to increase heterozygosity of the gene pool and increase the population sizes since species are going nearly extinct due to human impacts. This study is unique in that…
