Mutations
A change in genetic information

• Can occur randomly (naturally)
• Can be deliberately caused in the laboratory by
  scientists
• Inherited
• Not always harmful

These are not albinos they have pigmented eyes

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

HUMAN INTERVENTION

SELECTIVE BREEDING

• The selection of certain seeds or animals for
  reproduction in order to influence the traits
  inherited by the next generation

19
SELECTIVE BREEDING

• Liger - result of breeding a female TIGER to a
  male LION
• Has stripes and spots - stripes inherited from
  tiger parent spots from lion parent
• On their hind legs, ligers stand approximately 12
  feet tall. At most, ligers may weigh up to 1,000
  pounds

Geep - These are the result of a sheep and a goat
23
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.

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

French genetic researchers created Alba for artist Eduardo Kac. Thanks to genes borrowed from a jellyfish, the albino rabbit glows green when placed under special lighting. In regular light, Alba appears like any other furry white rabbit. But place her under a black light, and her eyes, whiskers and fur glow a otherworldly green.
