9
Diploid Cell 2N = 4 Two Homologous Chromosomes
10
Interphase 1 DNA is synthesized during the S phase
11
Prophase I: (1)The duplicated chromosomes condense and become visible. (2) Spindle forms.
12
(3) The nucleolus disperses (4) The nuclear membrane disperses
13
(5) Homologous chromosomes pair
14
(6) and cross over
15
Metaphase I Paired homologous chromosomes align at the metaphase plate
16
Anaphase I The homologues separate from each other, but sister chromatids remain linked at their centromeres
17
Telophase I: Cytokinesis that follows produces 2 daughter cells, each has 2 chromosomes consisting of 2 sister chromatids
