Biological Change Over Time:

Mutations & Selective Breeding

Mutations:

Some Are Inherited

The Source of Genetic Variation

They Can Be...

There are many different types of mutations

  • Induced
  • Through gametes
  • Harmful Mutations
  • Beneficial Mutations

There Are...

  • Spontaneous
  • Neutral Mutations
  • Point Mutations
  • They can be dominant or recessive
  • Chromosome Mutations

Selective Breeding:

  • To domesticate animals

Artificial Selection of Traits

  • To breed desirable traits
  • To increase size

Can be used to...

  • Reduce genetic variance/prevent mutations
