Question
______ is the cell division process that occurs in diploid germ cells and gives rise to haploid cells.
Solution
The cell division process that occurs in diploid germ cells and gives rise to haploid cells is called Meiosis.
Here are the steps of Meiosis:
-
Interphase: The DNA in the cell is copied resulting in two identical full sets of chromosomes.
-
Prophase I: The chromosomes condense and pair up.
-
Metaphase I: The paired chromosomes align at the cell's equator.
-
Anaphase I: The pairs of chromosomes, also known as sister chromatids, are pulled apart by the spindle fibers and move to opposite ends of the cell.
-
Telophase I and Cytokinesis: The cell splits into two new cells, each with one full set of chromosomes.
-
Prophase II: The chromosomes condense again.
-
Metaphase II: The chromosomes align at the cell's equator, similar to metaphase I.
-
Anaphase II: The sister chromatids are pulled apart by the spindle fibers and move to opposite ends of the cell.
-
Telophase II and Cytokinesis: The cells split again resulting in four new haploid cells.
Each of these cells contains half the number of chromosomes as the original cell. In humans, this means each cell contains 23 chromosomes.
