Mitosis and Meiosis

Front

What are sister chromatids?

Back

Two identical copies of a chromosome.

Front

What phase of which cellular process is this cell in?

Back

Metaphase I ; Meiosis.

Front

What is the significance of crossing over during meiosis?

Back

It increases genetic variation by exchanging portions of chromatids.

Front

Which process divides the cytoplasm into two cells?

Back

Cytokinesis.

Front

When do homologous chromosomes separate during meiosis?

Back

Anaphase I.

Front

What is mitosis?

Back

The process of cell division that results in two identical daughter cells.

Front

What is meiosis?

Back

A type of cell division that reduces the chromosome number by half, producing four genetically different gametes.

Front

Define cytokinesis.

Back

The division of the cytoplasm during cell division.

Front

What are homologous chromosomes?

Back

Chromosomes that have the same sequence of genes and structure, one inherited from each parent.

Front

What occurs during prophase I of meiosis?

Back

Chromosomes condense, homologous chromosomes pair up, and crossing over occurs.
