Chromosomes crossing over

Chromosomes crossing over

During meiosis, homologous chromosomes (1 from each parent) pair along their lengths. The chromosomes cross over at points called chiasma. At each chiasma, the chromosomes break and rejoin, trading some of their genes. This recombination results in genetic variation.

Discover What Occurs During the Stages of Meiosis: Anaphase I

What Occurs During the Different Stages of Meiosis?

Meiosis occurs in eukaryotic organisms that reproduce sexually. Explore what occurs in each phase of this cell division process.

Stage-By-Stage Guide to Mitosis: Anaphase

The Stages of Mitosis and Cell Division

During mitosis, chromosomes are duplicated and divided evenly between two cells. The process begins with interphase and ends with cytokinesis.

Stage-By-Stage Guide to Mitosis: Prophase

The Stages of Mitosis and Cell Division

During mitosis, chromosomes are duplicated and divided evenly between two cells. The process begins with interphase and ends with cytokinesis.

Stage-By-Stage Guide to Mitosis: Metaphase

The Stages of Mitosis and Cell Division

During mitosis, chromosomes are duplicated and divided evenly between two cells. The process begins with interphase and ends with cytokinesis.
