Meiosis II Overview

These flashcards cover key terms and concepts related to Meiosis II, including phases of meiosis, genetic variability, and the comparisons with mitosis.

Meiosis II

The second division of meiosis, resulting in four haploid daughter cells.

Prophase II

The stage in meiosis II where chromosomes condense, and the spindle apparatus forms.

Metaphase II

Chromosomes align at the metaphase plate during meiosis II.

Anaphase II

Sister chromatids separate and move toward opposite poles during meiosis II.

Telophase II

The phase in meiosis II where the nuclear envelope re-forms, resulting in four haploid cells.

Bivalents

Paired homologous chromosomes during prophase I of meiosis.

Crossing Over

The exchange of genetic material between homologous chromosomes during prophase I.

Cytokinesis

The process that follows telophase, resulting in the division of the cytoplasm.

Genetic variability

The diversity in gene frequencies which is a result of processes like crossing over during meiosis.

Synapsis

The pairing of homologous chromosomes that occurs during prophase I of meiosis.

Daughter Cells

The resulting cells after meiosis, which are haploid.

Comparison of Mitosis and Meiosis

In mitosis, chromosomes align individually at the metaphase plate, while in meiosis, homologous chromosomes align independently.
