6.5b The Stages of Meiosis II Flashcards
How is meiosis II different from meiosis I?
There is no interphase between meiosis I and meiosis II so the DNA is not replicated
What is meiosis II similar to?
The stages of mitosis.
What happens in Prophase II?
The nuclear envelope breaks down and chromosomes condense
A spindle forms at a right angle to the old one
What happens in Metaphase II?
Chromosomes line up in a single file along the equator of the spindle
What happens in Anaphase II?
Centromeres divide and individual chromatids are pulled to opposite poles
This creates four groups of chromosomes that have half the number of chromosomes compared to the original parent cell
What happens in Telophase II?
Nuclear membranes form around each group of chromosomes
What happens in cytokinesis in meiosis II?
Cytoplasm divides as new cell surface membranes are formed creating four haploid cells
