Mutations

A change in genetic information

  • Can occur randomly (naturally)

  • Or can be deliberately caused in the laboratory by scientists

  • Inherited

  • Not always harmful

These are not albinos; they have pigmented eyes.

Albinos l.jpg

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 l.jpg

SELECTIVE BREEDING

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

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.

The Cama is the result of breeding a Llama to a Camel.Parents in background of picture.

The Zebroid is the result ofbreedinga female Horse and a male Zebra.

The Zedonk / Zonkey is the result of breeding a female Donkey and male Zebra.


Slide21 l.jpg

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 l.jpg

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.
