Question

Match the major events of meiosis with the stage in which the events occur. Answers may be used more than once.

1.Homologous chromosomes are held together by the synaptonemal complex in synapsis

2.Two haploid daughter cells form, each having duplicated chromosomes

3.Nuclear envelope re-forms around the chromosomes

4.Tetrads align at the metaphase plate

5.Duplicated chromosomes separate at the centromere

6.Four haploid daughter cells form, each with a set of unduplicated chromosomes

7.The centrosome has duplicated in preparation for meiosis

8.Non-sister chromatids exchange genetic information during crossing over

9.Division of the cytoplasm occurs

10.Homologous chromosomes separate and move toward opposite poles

11.Duplicated chromosomes are aligned at the metaphase plate

12.Daughter (Unduplicated) chromosomes are moved to opposite poles

13.The nuclear envelope breaks down

14.Chromosomes are not yet visible; DNA is in its long, stringy, uncoiled state

A. Metaphase II B. Gap phase 2 C. Prophase I and Prophase II D. Telophase I and Cytokinesis E. Telophase I/II and Cytokinesis F. Prophase I and Prophase II G. Telophase II and Cytokinesis H. Metaphase I I. Prophase I J. Anaphase I K. Anaphase II

Place letter in appropriate event. Thanks
