Mendels Laws

• Law of Dominance
• Law of Segregation
• Law of Independent Assortment

17
Meiosis

• Diploid/Haploid
• Gametes Egg/Sperm
• Genetic Recombination
• Crossing-over/Ind. Seg.
• Zygote
• Mutations Frame Shift/Point

Independent Assortment and Segregation
19
Mitosis

• Process in which threadlike nuclear material is
  divided equally between two daughter cells.
• Mitosis keeps the number of chromosomes constant
  from one cell generation to the next.

20

• Growth and tissue repair
• Asexual reproduction in many organisms binary
  fission, budding, and fragmentation.

Genetic Engineering

• Researchers use recombinant DNA technology to
  analyze genetic changes.
• The cells copy the foreign DNA right along with
  their own DNA.
