Mitosis is the division that results in two “daughter” cells. Both of these daughter cells have the same number of chromosomes as the “parent” cell.
Mitosis consists of 4 phases: prophase, metaphase, anaphase, and telophase.
Prophase: the DNA is copied and the chromosomes pair up
Metaphase: the chromosomes line up in the middle of the cell
Anaphase: sister chromatids are pulled apart from each other towards opposite sides of the cell
Telophase: the cell begins to pinch in the middle and separates into two identical daughter cells
There are approximately 12 transisthmian shrimps species, called sister species because they cannot interbreed effectively, in the Isthmus of Panama. It is believed that the closure of the Panama resulted to allopatric speciation of the shrimp population within the region.
