Breeding

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…

through Gene Therapy and Selective Breeding Gene Therapy → explain the processes involved Gene therapy is the process of altering an existing gene in the DNA and inserting it into cells in an organism to fix genetic disorders or diseases. In humans, gene therapy is the process in which some of the defect cells or the cells carrying the disease are removed from the body (eg. lung cells in a Cystic Fibrosis patient) in order to harvest their DNA. The base sequence of their DNA is then altered to…

perfect? Obviously not, as some trait variations cannot be proven to be better than others, but that doesn’t mean no one has tried. Selective breeding is now most commonly used in plants, however, it has unfortunately been forced upon people as well. To explain, the act of choosing traits that are deemed perfect or greater than others is called selective breeding. Specifically, “Artificial Selection is the form of selection in which humans actively choose which traits should be passed onto…

Breeding: Luyster et al. (2006) state that before breeding season starts, around January, the breeding animals should be given a physical exam, and any health problems should be addressed. During this time, the facilities need to determine the SSP breeding recommendations. A list of up to four males should be made, with the first choice being housed in the adjourning cage. It is found that females are more fertile in their first three years, and males are more fertile until they are about five.…

Cross breeding plays an important part in the future of endangered animals. In the case of polar bears it may lead more quickly to the extinction of them. Within the past 10 years scientist have found several bears sharing DNA, in this case the two bears sharing the DNA are the polar bears and the grizzly bear. The earth has been heating up which means that the polar bears are getting pushed out of there land space, and are even starting to die off. The polar bears have to expand into the…

Humans and dogs have been living side by side for over 14, 000 years (Prestrude and O’Shea, 1996; Riddle, 1987). Throughout the years dogs have served as hunters, guards, herders, medical subjects, companions and guides for humans. Dog selection for a particular task is often based on pairing the task to the breed, attempting to choose one with the appropriate physical, personality, and psychological attributes (Weiss and Greenberg, 1997) (e.g. Jack Russell Terriers’ high stamina and high energy…

genetically different from the founding stock that was adopted by the humans: the Canis familiaris” (Vila, 2017). In1850’s German Dog breeders selected and bred dogs that they believed had the skills necessary for herding sheep through selective breeding. They looked and observe dog for qualities that consisted of speed, intelligence, strength…

Inbreeding is a type of breeding that puts two dogs from the same blood line to mate. “The roots of their genetically caused problems came about over the past two centuries, as dog shows became popular and people began selectively inbreeding the animals to have specific physical features”(Maldarelli). This causes their future generations which are today’s dogs to become messed up and coming out as genetic monsters. People shouldn’t be allowed to inbreed dogs because they could be born with…

Lesson 10 Review Questions 1. Puppies born in commercial breeding facilities (i.e. puppy mills) do not receive proper socialization; what are behavioral problems that may result later in life? What are some physical health problems that occur in puppies from puppy mills?? What are some physical health problems that occur among the breeding stock?? As a result of not getting socialization at a young age many problems can happen. The puppies could grow up and become afraid of everyone, become…

puppy mills. These puppy mills are known as large-scale commercial dog breeding facilities which give revenue priority over the well-being of the dogs and puppies, ultimately resulting in sickly and unhealthy animals. Due to this, many of the dogs that pet stores carry today have faced a life of malnutrition, disease, and abuse. Despite the immense abuse the dogs and puppies of the puppy mills endure, the large scale breeding of animals is still legal, forcing innocent animals to live in cruel…
