For this reason selective breeding is sometimes called artificial selection. Different varieties of plants and animals with desired characteristics can be developed by selective breeding.
...

- chickens that produce large eggs.

Can humans be selectively bred?
Eugenics is essentially selective breeding applied to humans. ... The word eugenics was coined by Francis Galton (1822-1911), an English scientist who also came up with the idea that people are shaped by both “nature” and “nurture”.
Is selective breeding good for animals?
2. It allows for higher profit. Selective breeding allows the encouragement of plant and animal characteristics that are more beneficial to farmers. For example, if they have selectively bred cows, these livestock can produce more milk than those typically bred, and the gene can be passed on to their offspring.
What are sheep selectively bred for?
Improving meat quality, including taste and tenderness, is critical to the protection and development of markets for sheep meat.
How were cows selectively bred?
What exactly is selective breeding? Especially the dairy industry is interested in getting cows to produce more milk, which is why farmers involved in it use selective breeding. That can be done with the help of artificial insemination, as that allows the farmers to pick the sex of the calf being born.
Can a gorilla and a human breed?
He said: “All of the available evidence both fossil, palaeontological and biochemical, including DNA itself, suggests that humans can also breed with gorillas and orang-utans. “Humans and all three of the great apes species are all descended from a single common apelike ancestry.
Can humans breed with any other animals?
Probably not. Ethical considerations preclude definitive research on the subject, but it's safe to say that human DNA has become so different from that of other animals that interbreeding would likely be impossible. ... In general, two types of changes prevent animals from interbreeding.
What plants can be selectively bred?
Broccoli, cabbage, cauliflower, and kale are all selectively bred descendants of the wild mustard plant. Wild tomatoes were about the size of blueberries before we selectively bred them to be much larger.
Are dogs an example of selective breeding?
The most obvious examples of selective dog breeding are purebred dogs, but selective breeding commonly happens at every supervised and planned breeding.
Do dogs have selective breeding?
There are over 400 breeds of dog in the world and all are maintained as pure-bred stocks through selective breeding, which aims to maintain a closed genetic lineage. Most dog traits follow simple genetic rules. Traits are often referred to as being dominant or recessive.
Is it cruel to breed animals?
Regardless of size, every breeder is responsible for exacerbating the overpopulation crisis. In a time of extreme companion animal overpopulation, breeding dogs is always irresponsible and cruel. Dog breeders treat living individuals as commodities to be genetically manipulated for profit.
Why are lions selectively bred?
A recessive gene gives white lions their unusual colors. A similar gene also produces white tigers. White lions can therefore be selectively bred for zoos, animal shows and wildlife parks. ... Some are concerned about white lions mating with lions of other alleles, due to possible extinction of the white lion allele.
What dogs have been selectively bred for?
Selective breeding
Most dog breeds were originally selected for particular purposes, such as hunting or guarding property. Humans selectively bred dogs that were best suited for the various roles required of them, based on their fitness, ability and utility.
What characteristics are pigs selectively bred for?
Modern pigs have been selectively bred for fast growth which can lead to lameness. The pigs are unable to support their own rapid weight gain. Around 15% of pigs are estimated to suffer from lameness but this may be higher in some herds.
How were watermelons selectively bred?
Seedless watermelon was created by selectively breeding two different types of watermelon plants. To create seedless watermelons, young watermelon plants are treated with colchicine. Colchicine causes crossing male pollen containing 22 chromosomes per cell, with a female watermelon flower with 44 chromosomes per cell.
How are camels selectively bred?
The process involves having the high-milk-producing female camel produce more eggs, or ova, by being injected with a female hormone. The female is then mated with a selected male, or bull, and once the female's eggs are fertilised, they are removed from its uterus through a non-surgical "flushing" technique.
How were carrots selectively bred?
While the carrot most likely originated in Central Asia, it made its way both West and East. ... The Dutch were the ones to selectively breed the orange carrot. Modern genetic studies show that they took the yellow rooted carrot and over generations, created an orange carrot that was healthier and less bitter.
