Question

Phases of meiosis on the lines provided, identify the stage of meiosis i or meiosis ii in which the event described occurs. 9. each replicated chromosome pairs with its corresponding homologous chromosome. 10. crossing-over occurs between tetrads. 11. paired homologous chromosomes line up across the center of the cell. 12. spindle fibers pull each homologous chromosome pair toward an opposite end of the cell. 13. a nuclear membrane forms around each cluster of chromosomes and cytokinesis follows, forming two new cells. 14. chromosomes consist of two chromatids, but they do not pair to form tetrads. 15. a nuclear membrane forms around each cluster of chrom

Answer 1

Meiosis I
Prophase I - homologous chromosomes form a tetrad, where they begin cross-over through the process of synapses.
Metaphase - homologous chromosomes then align along the metaphase plate.
Anaphase I - spindles then separate the homologous chromoses, pulling them to opposite poles of the cell
Telephase I - the cell creates a cleavage burrow inwhich the cell divides into two new cells with 46 chromosomes in the process of cytokinesis

Meiosis II
The same as mitosis
Prophase II - Nuclear envelope disintegrates, Sister chromatids migrate towards the metaphase plate.
Metaphase II - Sister chromatids align along the plate by their centromere.
Anaphase II- spindles pull the chromatin to opposites poles
Telephase II- cleavage burrow forms and cells seperate through cytokinesis

end result
4 haploid gametes are formed
