Should intentional animal cross-breeding be legal?
Transcript of Should intentional animal cross-breeding be legal?
Tigon- A cross between a male tiger and a lioness.
Leopon- A cross between a lion and a leopard.
Jagulep- A cross between a jaguar and leopard.
Savannah cats- A cross between a domestic cat and a serval. They can be trained like dogs. Cats Zebroids Zorse- A cross between a horse and a zebra.
Zony- A cross between a pony and a zebra.
Zonkey- A cross between a donkey and a zebra. Bears Grolar bear- A cross between a polar bear and a grizzly bear. They are sometimes naturally found in the wild, because polar bears are being driven out of their natural habitat, into grizzly bear territory. Wholphins- A cross between a false killer whale and an Atlantic bottlenose dolphin.
Narluga- A cross between a narwhal and a beluga whale. Marine Animals Farm Animals Beefalo- A cross between a buffalo and a cow.
Geep- A cross between a goat and a sheep.
Mule- A cross between a male donkey and a female horse.
Hinny- A cross between a female donkey and a male horse.
Iron Age Pig- A cross between a domestic pig and a wild boar.
Cama- A cross between a llama and a camel. The mule is the most common type of hybrid animal. The First Hybrid Animal First recorded hybrid animal was the mule, a mix between a horse and a donkey.
Used thousands of years ago by ancient Greeks and Romans.
Infertile, so dependant on human intervention.
Mules from a mare and a male donkey are usually easier to train.
Greeks and Romans used mules instead of horses because they could bear heavier loads and can work longer without rest. Books Grant, V. E. (2011). Hybrid. Encyclopedia Americana. Retrieved April 14, 2011, from Grolier Onlinehttp://ea.grolier.com/article?id=0210080-00 With animals, there are pairs of genes in the DNA that control every aspect of the animal.
If the genes are simplified to three major genes (AA, BB, CC), it will be easier to explain. For example, one pair of genes could control the size of the animal (AA), one could control the colour (BB), and another could control the speed (CC).
Example of how a hybrid animal is created:
AA BB CC: gives a large animal, black colouring and fast.
aa bb cc: gives a small animal, white colouring and slow.
If these two animals mate, it will produce a hybrid with genes Aa Bb Cc. Websites Nelson,Brian, 2011, 11 Amazing Hybrid Animals, May 5, 2011,
http://www.mnn.com/earth-matters/animals/photos/11-amazing-hybrid-animals/mixing-things-up How Hybrid Animals are Created Some hybrid animals naturally breed with each other.
For example, the parents of Pippi the zonkey, a male zebra and a female donkey, were just kept in the same pen, and they bred. "Donkeys and zebras have been living here for years without breeding, so Pippi was a big surprise," says C.W Wathen, Chestatee Wildlife Preserve founder and manager. What is a Hybrid Animal? History of Hybrid Animals Definitions Hybrid animals are the offspring of cross fertilization between more or less distantly related groups.
Cross breeding is to produce a hybrid. On April 16, 2006, a hunter in the Northwest Territories shot the first ever pizzly bear, AKA grolar bear, in the wild.
Scientists had made other pizzly bears in captivity. 2003, Zorse Breed Description, May 7, 2011,http://www.equinepost.com/resources/breeds/showBreed.asp?ID=150 Grolar Bears Magazines Jazynka, Kitson, 2011, Half Zebra, Half Donkey, Washington D.C 20036, National Geographic Society. Newspaper Carrol, Sean B., 2010, Hybrids May Thrive Where Parents Fear to Tread, New York, New York Times. To maximize the chance of the hybrid animal being healthy and living longer, they should breed naturally.
This will improve survival rates, because the genes will be more similar, so there is a less chance of the animal being born with defects. Videos LigerChannel, 2008, The Truth About Ligers, May 11, 2011, YouTube.com Pros and Cons Pros Cons Hybrid animals can be a better source of food that is higher in nutrients and lower in fat.
Can do more physical labour and are trained easily.
Raise awareness for endangered animal conservation.
Have Hybrid Vigor, which means they are stronger, bigger and healthier than parents.
Are hardier than other animals, so usually need less care. Can't predict how the animal will turn out.
May have mental or physical defects.
Costs millions of dollars to produce and care for hybrid animals artificially.
Majority are infertile, so they cannot reproduce. Why People Make Hybrid Animals There are five main reasons why people make hybrid animals. For physical labour.
To raise awareness about endangered species.
Accident, in the wild.
To experiment with bio-engineering. Zonkeys, zorses, camas, geeps, mules and hinnies are made for physical labour.
Beefalo and Iron Age Pig are used for food.
Liger, tigon, leopon, jagulep are used to raise awareness for endangered animals.
Grolar bears, ligers, tigons, zonkey, wholphin and narluga were all made accidentally or in the wild.
Grolar bears, camas, geeps are made for experimenting with bio-engineering. Where do You Find Hybrid Animals? The Institute of Greatly Endangered or Rare Species (T.I.G.E.R.S), in Myrtle Beach, South Carolina. This is where 4 ligers are kept.
Sea Life Park in Hawaii. 2 wholphins are being kept there.
Perth Pork Products Ltd. in Sebringville, Ontario, where Iron Age Pigs are farmed.
Longview, Alberta, where there is a beefalo farm.
Northern Canada, where there are some wild grolar bears.
Dubai Camel Centre, where there are 3 camas.
A zoo in Chicago, where there is a jagulep. Most hybrid animals are made by artificial insemination.
This is when the semin of the male animal is artificially inserted into the reproductive system of the female animal.
Artificial insemination is mainly used when the animals are too different in size and shape to naturally breed.
Rama the cama was born by artificial insemination,
This was because his parents, a llama and a camel were too different in size to breed naturally. About 25 years ago, the first ever wholphin was born.
The wholphin was born in Sea Life Park,Hawaii. Wholphins Zorses were first bred in Africa at the turn of the 19th century.
Meant to be beasts of burden. Zorses Beefalo were created to combine the best characteristics of buffalo and cow for meat production.
Accidental cross breeding as far back as 1749, in early European settlements in North America.
First intentional cross breeding during early 1800s, then called cattalo. Beefalo I think that intentional animal cross-breeding should continue to be legal, as long as it is done naturally, not artificially.
I say this because the animals usually will not have mental or physical defects, and the animals choose whether they want to mate or not.
I think that it shouldn't be done to experiment with bio-engineering, because then the animals would be poked and prodded and kept in a lab their whole life. Just because a hybrid animal's genes are combined with another animal doesn't mean that the animal's personality has to be combined, too.
