Selective Breeding: allowing only those animals with desired characteristics to produce the next generation

Hybridization: crossing dissimilar individuals to bring together the best of both organisms

Inbreeding : the continued breeding of individual with similar characteristics

What is the purpose of selective breeding?-Humans use selective breeding, which takes advantage of naturally occurring genetic variation in plants, animals, and other organisms, to pass desired traits on to the next generation of organisms

Why might breeders try to induce mutation?-Breeders can increase the genetic variation in a population by inducing mutations, which are the ultimate source of genetic variability

Done by humans Take advantage of naturally

occurring genetic variationHybridization Disease resistance of one plant

and food producing in another created a strong mass food producing plant.

Inbreeding Ensures that the characteristics

stay the same in the animals Can cause genetic defect by

bringing together 2 recessive alleles

Variation increases by adding genetic mutations which are the ultimate source of genetic variation

scientist have developed hundreds of useful bacterial strains

Produces “Mutant plants” through polyploidy
