Meiosis II CP-Biology

Front

What is the main purpose of Meiosis II?

Back

To separate sister chromatids and produce four haploid cells from one diploid cell.

Front

What happens during Telophase II?

Back

The nuclear envelope reforms around each set of chromosomes, and the chromosomes begin to de-condense.

Front

What is the difference between Meiosis I and Meiosis II?

Back

Meiosis I separates homologous chromosomes, while Meiosis II separates sister chromatids.

Front

How many chromosomes are present at the start of Meiosis II in humans?

Back

46 chromosomes (23 pairs of homologous chromosomes).

Front

What is the role of spindle fibers during Meiosis II?

Back

Spindle fibers help align and separate the chromosomes during Metaphase II and Anaphase II.

Front

What occurs during Anaphase II?

Back

Sister chromatids are pulled apart to opposite poles of the cell.

Front

What is the result of cytokinesis following Meiosis II?

Back

Four genetically distinct haploid cells are formed.

Front

What is the significance of crossing over in Meiosis I?

Back

Crossing over increases genetic diversity by exchanging genetic material between homologous chromosomes.

Front

What is the equatorial plane in the context of Metaphase II?

Back

The equatorial plane is the imaginary line where chromosomes align before being separated.

Front

What is the term for the two identical halves of a duplicated chromosome?

Back

Sister chromatids.
