27. On your own, in your spiral (right)
On your own, in your spiral (right). Place the following terms into a Mitosis Vs Meiosis Venn Diagram
Involves 1 cell division
Starts with Diploid parents cell
Prophase, metaphase, anaphase, telophase
Results in 2 diploid cells
Creates gametes
Cells are identical
In metaphase II homologous chromosomes line up
Involves 2 cell divisions
Prophase II metaphase II anaphase II telophase II
Ends with cytokinesis
Results in 4 haploid cells
Creates somatic cells
In metaphase, individual chromosomes line up
