Meiosis II exam Flashcards

The second division in meiosis, resulting in four genetically diverse haploid gametes.

Two haploid daughter cells from meiosis I.

The phase in meiosis II where chromosomes condense and the nuclear envelope breaks down.

In metaphase II, chromosomes align in a single row, unlike the two rows in metaphase I.

The phase in meiosis II where sister chromatids separate and move to opposite poles.

Four genetically diverse haploid cells.

The phase in meiosis II where nuclear membranes form around each set of chromosomes, resulting in four haploid cells.

Both involve the separation of sister chromatids and have similar phases: prophase, metaphase, anaphase, and telophase.

Achieved through processes like crossing over and independent assortment.

Chromosomes align in a single row at the cell's equator.

Another term for meiosis II, as the ploidy number remains equal (haploid to haploid).

It produces haploid gametes (sperm or eggs) essential for maintaining genetic diversity.

Identical copies of a chromosome connected by a centromere, separated during anaphase II.

Meiosis II starts with haploid cells, while mitosis starts with diploid cells.

Cells with a single set of chromosomes, produced at the end of meiosis II.

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

Chromosomes condense, spindle fibers form, and the nuclear envelope breaks down.

Four haploid cells.

Nuclear membranes form around each set of chromosomes, resulting in four distinct haploid cells.

Haploid.

Metaphase II.

The variety of different genetic makeups within a population, enhanced by meiosis.

They are separated and pulled to opposite poles of the cell.
