Cell Division (Meiosis) Overview

Flashcards covering key concepts and terms related to meiosis and cell division.

Meiosis

The process of producing haploid cells from diploid cells through two rounds of division.

Meiosis Pmat of humans

Haploid

A cell that has half the number of chromosomes, denoted as n.

Diploid

A cell that has two complete sets of chromosomes, typically denoted as 2n.

Prophase I

The first stage of meiosis I where homologous chromosomes pair and crossing-over occurs.

Metaphase I

The stage in meiosis I where homologous chromosomes align at the metaphase plate.

Anaphase I

The stage in meiosis I where homologous chromosomes are pulled apart to opposite poles.

Telophase I

The stage in meiosis I where the nuclear envelope reappears around two haploid daughter cells.

Meiosis II

The second round of meiotic division where sister chromatids are separated, leading to four unique haploid cells.

Crossing-over

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

Cytokinesis

The final stage of cell division where the cytoplasm divides, resulting in two new daughter cells.

Prophase II

Centrioles doubled and move to opposite ends

Metaphase II

Centrioles release spindle fibers

Anaphase II

Chromosomes are separated from each other

Telophase II

Spindle fibers are gone
