Final Jeopardy Category
List all the stages of Meiosis I and II and describe what happens in each stage
Final Jeopardy Answer Prophase I Chromosomes begin to condense, crossing over
can take place. Metaphase I The chromosomes line up in the middle and the
spindle becomes fully formed Anaphase I The poles push apart and the chromosomes are
pulled apart from their homologous partners Telophase I The germ cells cytoplasm separates and there are
now two haploid cells Prophase II Microtubules attach to the chromosomes and
drive the movement toward the spindles middle
Metaphase II Chromosomes are positioned at the spindle equator, midway between the two poles
Anaphase II the attachment between the two chromatids of each chromosome break. They move to opposite poles of the spindle
Telophase II The cells begin to separate and we are left with four new daughter cells. They will have a haploid number.
