15.1 Selective Breeding

Vocabulary:

  1. selective breeding
  2. hybridization
  3. inbreeding
  4. biotechnology

What is selective breeding used for?

Human use selective breeding to pass desired traits on the next generation.  Populations have variations, some of which are considered useful to humans.  By choosing and crossing organisms that possess the desired traits, the offspring will likely also have the desired trait.

There are two methods of selective breeding.

1.  Hybridization where dissimilar individuals with the desired traits are crossed.

Example:  horse + donkey = mule

2.  Inbreeding  continued breeding of individuals with similar characteristics.

 

How do people increase genetic variation?

Breeders can increase the genetic variation in a population by introducing mutagens.
