Breeding

The use of artificial insemination in dairy cattle selective breeding enables the best bulls and cows are chose to improve the genetic make-up such as qualities - milk fat content and quantity of milk in the dairy cow population. This helps to prevent the spread of diseases that can result from normal sexual reproduction because AI is done using sterile procedures also the use of AI can minimize injury to the cattle population that caused by aggressive bulls during the mating process. The use…

Irresponsible Breeding of our Canine Friends In this day and age of the modern and impatient, society has forsaken our most loyal companions. They have sentenced their canine friends and their lineage to a life of cages and ultimately – death. This is due to the impetuous actions of the individuals and people among society and their failure to educate themselves on how to properly care for their animals. We live in a society with an enormous census of unwanted and excessively bred animals for a…

Selective breeding is the human interference in the genetic transfer in animals and plants. Humans take the idea of natural selection where instead of the environment selecting for the alleles that are best suited for the organism to survive in the wild, humans select rare desirable phenotypic traits in organisms and breed them with each other in order produce an offspring containing those traits. Desirable traits include leaner meat in animals, or better quality milk in cows for commercial uses…

Plant breeding has been around for hundreds of thousands of years. When people in the modern era of the human species think about plant breeding, most thoughts turn towards genetically modified organisms or GMOs for short. However, plant breeding doesn’t just involve genetically modified organisms. Plant breeding can be much less complicated. Farmers have bred plants for longer than the lifespan of genetically modified organisms. Early farmers’ version of plant breeding was as simple as choosing…

Introduction Selective breeding is the characteristics of an animal or plant. Selective breeding is done by the different characteristics, by the parents of the plant/animal/human of the baby. In this essay I’m going to talk about why you should and shouldn’t have a Maltese Shih Tzu as a pet and why. I will also talk about where they use selective breeding. The animal I’m focusing on is a Maltese Shih Tzu dogs. History The history behind the Maltese Shih Tzu is they started breeding in the…

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…

passed from one generation to the next. Careful cross breeding may lower the chances of passing on a particular condition if only one parent is a carrier.Keep in mind that many of today's purebred dogs were founded on crosses of different breeds, and they have been refined through selective breeding to produce the consistent characteristics they display today. Now it's time to consider some of the potentially negative aspects of cross breeding. Many cross breeders downplay the significance of…

This class has made me question everything we have learned as zookeepers/animal lovers, honestly. I started thinking about how we breed animals, how we house them, and how we feed and clean them. The biggest change I have made personally is to not clean the entire ferret cage in one day. Since it is 4 stories, I now clean 2 stories at a time. I noticed that their behavior towards the clean section is different and they spend less time in it compared to the section that I did not clean. This…

One of the topics that I found out about, that I believe is related to evolution is dog breeding. Through the years, we have heard of people paying a lot of money for a very specific breed of dog. This is called artificial selection, where we as humans direct the trait that gets passed down to a future generation of a dog. Sometimes that is taking characteristics of one breed and mixing it with another breed that also has certain characteristics that are appreciated. There are not any new…

clean, and a few other tasks that are important to life on their planets, but not as important as the Breeding Program. Since the females have long age died out, the males of the higher class started to follow due to the lack of births. The higher and lower classes can not por-create. So the males have been taking women with DNA matches from other planets, to breed with. So the job at the Breeding Program is to look through the endless folders of DNA of females that have ever been born,…
