Weird Genetics :Weird Genetics
Mutations :Mutations http://www.accessexcellence.org/ A change in genetic information Can occur randomly (naturally)
Or can be deliberately caused in the laboratory by scientists
Inherited
Not always harmful
Natural Mutations :Natural Mutations
Slide 4 :These are not albinos; they have pigmented eyes.
Slide 5 :White Bengal Tiger
ALBINOS :ALBINOS Little or no pigmentation in the eyes, skin, and hair (or in some cases in the eyes alone).
Inherited an altered copy of a gene that does not work correctly.
The altered gene does not allow the body to make the usual amounts of a pigment called "melanin".
True albinos have pink eyes and skin.
Slide 8 :White Bluebonnets
Slide 9 :Pink Bluebonnets
HUMAN INTERVENTION :HUMAN INTERVENTION
SELECTIVE BREEDING :SELECTIVE BREEDING The selection of certain seeds or animals for reproduction in order to influence the traits inherited by the next generation.
SELECTIVE BREEDING :SELECTIVE BREEDING The Liger is the result of breeding a female Tiger to a male Lion.
The liger has both stripes and spots. The stripes are inherited from its tiger parent and the spots from the lion parent.
On their hind legs, ligers stand approximately 12 feet tall. At most, ligers may weigh up to 1,000 pounds.
Slide 18 :The Cama is the result of breeding a Llama to a Camel.Parents in background of picture.
Slide 19 :The Zebroid is the result of breedinga female Horse and a male Zebra. The Zedonk / Zonkey is the result of breeding a female Donkey and male Zebra.
Slide 21 :The Mule is the result of breeding a female horse(mare) to a male donkey (jack). Themule is superior to the horse in strength,endurance, intelligence and disease resistance.
Slide 22 :Maroon & Red Bluebonnets
GENETIC ENGINEERING :GENETIC ENGINEERING The selective, deliberate change of genes (genetic material) by man.
The technique of removing, modifying or adding genes to a DNA molecule in order to change the information it contains.
