Meiosis

Question 1

Interphase

Answer 1

DNA replicates

Question 2

Prophase 1

Answer 2

homologous chromosomes condense and become visible
-crossing over occurs
-nuclear membrane breaks down
-centrioles migrate to oposite poles and produce spindal

Question 3

Metaphase 1

Answer 3

• spindle attaches to centromere
• homologous pairs line up along the equator
  -independent assortment occurs

Question 4

Anaphase 1

Answer 4

-spindle fibres contract
homologous pairs seperate and move towards opposite poles ( now called sister chromatids ( technically just chromosomes))
-independent assortment occurs

Question 5

Telophase 1

Answer 5

• chromosomes gather at poles
  -nuclear membrane reforms-haploid
  -cytokinesis0 division of cytoplasm

Question 6

End result of Phase 1

Answer 6

-2 unidentical haploid daughter cells

Question 7

Prophase 2

Answer 7

-nuclear membrane disintegrates
-centrioles migrate to opposite poles and produce spindle

Question 8

Metaphase 2

Answer 8

-spindle attaches to centromere
-chromosomes line up in single file along the equator
-independent assortment occurs

Question 9

Anaphase 2

Answer 9

spindle fibres contract
-chromosomes are pulled apart ( now sister chromatids)
-move towards opposite poles
-independent assortment occurs

Question 10

Telophase 2

Answer 10

-chromosomes gather at poles
-nuclear membrane reforms
-divison of cytoplasm

Question 11

End result Phase 2

Answer 11

4 unidentical haploid daughter cells
