My topic that I have chosen is selective breeding. Selective breeding is when either an animal or a plant is selected to be mated with another lifeform from its species for its genes, phenotypes and alleles to create the the perfect outcome they are looking for. whether it is their seed production rate or how much milk they can produce, it is all about supply and demand.
What is Selective Breeding?
Selective breeding is the process used by humans to breed animals and plants in a specific way to gain their way to having as close to a pure phenotype.
A phenotype is an observable characteristics, like the colour of your eyes or how big a trees leaves are. People find animals and plants with these characteristics and select them to mate with another to enhance to phenotype to create the best gene line for the future.
When it all Started
In 1859, a man named Charles Darwin studied the evolution of animals, people and plants. The christians found this to be blastphomic but it is now modern day science that is being improved every day. Charles Darwin wrote a book discussing about selective breeding and other types of breeding like inbreeding, linebreeding and outcrossing.
Selective breeding had been around for 1000's of years beforehand, but now that he found a new way to perform it, it has been looked down upon.
An Example of Selective Breeding
Dogs. There are over 400 recognised breeds of dogs and there are some that mankind want to preserve, making them a line of purebred. Dogs have papers to prove that they are from the line that they client wants. So if they wanted a purebred pug then they will have to go and see a specialised breeder to see the papers. a purebred dog can cost as little as $1000.
One of the most expensive dogs in the world.
How Selective Breeding is used in Everyday Life
Selective breeding is used in everyday life in livestock and in cultivation, with people making super cows that look like a swollen thumb to A pug that is a meter tall. People also use selective breeding in Horticulture by using specific seeds to do things like resist pesticides and disease, also lasting longer and staying fresher than others.
Argument in Society
Should selective breeding be allowed?
People could consider it cruel.
People might not eat it because they don't know the science behind it, They would become skeptical.
If a newborn doesn't appear the way they wanted, it's likely it will be euthanised which will make a lot of uproar.
Could solve problems with crop and livestock loss.
Makes it easier to identify problems and diseases, then help with eradicating it.
Could be the road to a healthier future for both us and the animals and plants
In conclusion, Selective breeding has been around for thousands of years and it has been put to great use making a lot of food and meat safer for humans to eat by fighting disease and bugs. It has also been great to make new breeds of animals that continue to excite the world.
