Using the information given, identify each of the stage of meiosis I through mei

Question

Using the information given, identify each of the stage of meiosis I through meiosis II (including interphase) on the lines to the left. One complete, number the stages in their proper order on the lines to the right. _____ Homologous chromosomes line up in the center of the cell _____ _____ Spindle fibers pull homologous pairs to opposite poles of the cell _____ _____ 4 haploid (n) daughter cells form _____ _____ Cells undergo a round of DNA replication _____ _____ Sister chromatids separate from each other _____ _____ 2 haploid (n) daughter cells form _____ _____ Kinetochore microtubules attach to the homologous chromosome pairs _____ _____ Individual chromatids move to each end of the cell _____ _____ Crossing-over (if any) occurs _____

Explanation / Answer

Stage Order

1. Metaphase I Homologous chromosomes line up in the center of the cell. 4th

2. Anaphase I : Spindle fibres pull homologous pairs to opposite poles of the cell. 5th

3. Telophase 2 : 4 haploid (n)daughter cells form. 9th

4. S phase of 1st interphase :Cells undergo a round of DNA replication 1st

5. Anaphase 2: Sister chromatids separate from each other. 7th

6.Telophase 1 :2 haploid (n) daughter cells form. 6th

7.Metaphase1 :Kinetochore microtubules attach to the homologous chromosome pairs. 3rd

8.Anaphase 2 :Individual chromatids move to each end of the cell. 8th

9.Prophase I and pachytene stage:Crossing over if any occurs 2nd
