Genetic Variations are caused by mutations in the genetic code or DNA.
Mutations can happen naturally due to errors during meiosis or mitosis. Exposure to radiation, viruses, chemicals can also cause mutations.
Some mutations have no effect at all while others can be harmful or helpful. Beneficial mutations may help an individual live longer and pass down the beneficial mutation to more offspring. (This is a driving factor of evolution.)
Cancer is caused by a mutation that allows the cells to grow out of control causing a mass or tumor.
A cama is a hybrid between a male dromedary camel and a female llama. The first cama was born on January 14, 1998. The aim was to create an animal with the size and strength of the camel, but the more cooperative temperament and the higher wool production of the llama.
The Czechoslovakian Wolfdog (or Vlčák/Vlčiak) is a relatively new breed of dog that traces its original lineage to an experiment conducted in 1955 in Czechoslovakia. After initially breeding 48 working line German Shepherd Dogs with 5 Eurasian wolves, a plan was worked out to create a wolf-dog hybrid that would have the temperament, pack mentality, and trainability of the German Shepherd Dog and the strength, physical build, and stamina of the Eurasian wolf.
Zebroid is the generic name for all zebra hybrids. The different hybrids are generally named using the convention of sire's name + dam's name. There is generally no distinction made as to which zebra species is used. Many times when zebras are crossbred, they develop some form of dwarfism.
Knowing the sequence of an organisms DNA allows researchers to study specific genes, to compare them with the genes of other organisms, to try to discover the functions of different genes and gene combinations
Transgenic organisms or Genetically Modified Organisms (GMO)
Organisms that contain genetic information from other species
How does one do this?
Take a gene from one organism and place it in another
This idea has sparked the new booming industry of biotechnology.
2. Fuse egg with a cell taken from another organism
3. Place in the uterus of a foster mother
4. Foster mother gives birth to cloned baby
Donor Nucleus These two cells are fused using an electric shock. Fused Cell The fused cell begins dividing normally. Embryo The embryo is placed in the uterus of a foster mother. The embryo develops normally into a lamb—Dolly Egg Cell An egg cell is taken from an adult female sheep. The nucleus of the egg cell is removed.
