When during meiosis do pairs of homologous chromosomes line up in the center of the cell?

In metaphase I, the homologous chromosomes line up at the metaphase plate. In anaphase I, the homologous chromosomes are pulled apart and move to opposite poles.

At what stage in meiosis are homologous chromosomes paired and lined up in the center of the cell quizlet?

Homologous chromosomes line up at the center of the cell (Metaphase=They MEET in the MIDDLE) Equator of cell.

At which stage in meiosis I do the pairs of homologous chromosomes come together?

During prophase I, the pairs of homologous chromosomes come together to form a tetrad or bivalent, which contains four chromatids. Recombination can occur between any two chromatids within this tetrad structure.

What lines up at the center of the cell during meiosis?

Explanation: In metaphase I, homologous chromosomes line up along the center of the cell in order to be pulled apart. Recall that during meiosis I, homologous chromosomes pair, cross over, and separate.

During which phase of mitosis do the chromosomes line up in the center of the cell quizlet?

During (metaphase II), all sister chromatids align themselves along the metaphase plate.

What are the two cell divisions in meiosis called?

Two successive nuclear divisions occur, Meiosis I (Reduction) and Meiosis II (Division). Meiosis produces 4 haploid cells. Mitosis produces 2 diploid cells. The old name for meiosis was reduction/ division.

What do 2 haploid daughter cells form?

Meiosis I results in two haploid (N) daughter cells, each with half the number of chromosomes as the original cell. The chromosomes (sister chromatids) line up in a similar way to the metaphase stage of mitosis along the equator. The sister chromatids separate and move toward opposite ends of the cell.

Why do chromosomes line up in the middle of the cell?

In animal cells, the chromosomes line up in the center of the cell. … Therefore, a safety mechanism called the spindle assembly checkpoint ensures that all of the chromosomes have correctly attached to the spindle before chromosome separation begins.
