The student knows that reproduction is a
characteristic of living organisms and that the
instructions for traits are governed in the
genetic material.  The student is expected
to(B) compare the results of uniform or diverse
offspring from sexual reproduction or asexual
reproduction(C) recognize that inherited traits
of individuals are governed in the genetic
material found in the genes within chromosomes in
the nucleus
Genetics and Heredity

• What do CELLS have to do with HEREDITY?!?

3
Cells contain

• Genetic material, found in genes in the
  chromosomes (pictured above) in the nucleus.
• Genetic material governs traits.
• Genes are passed from one generation to the next.
• Some organisms reproduce sexually.
• Others reproduce asexually.

Its all aboutReproduction

• Reproduction occurs at the cellular level.
• Sexual reproduction involves the joining of two
  sex cells (one from each parent), resulting in
  DIVERSE offspring.
• WHAT DOES DIVERSE MEAN?
• Asexual reproduction involves the duplication of
  genetic material and making an exact copy of one
  parent, resulting in UNIFORM offspring.
• WHAT DOES UNIFORM MEAN?

Inside an Animal Cell A Quick Review

  interactive animation.
• Inside the cell Click here to review the key
  parts of a cell. (Be sure to click on the
  nucleus!)
• Most plants and animals reproduce sexually.
• Sexually reproducing organisms have a different
  set of genes for every trait (called alleles).

  STOP this video at 234.)
• Plants that produce bulbs can reproduce
  asexually. Click here to see how.
