Meiosis and Genetic Variation Flashcard

Front

What is Interphase?

Back

Interphase is the phase of the cell cycle where the cell grows, replicates its DNA, and prepares for division. It occurs before both mitosis and meiosis.

Front

How many times does Interphase occur during Meiosis?

Back

Interphase occurs once during Meiosis.

Front

What is the main difference between Mitosis and Meiosis?

Back

Mitosis results in 2 genetically identical daughter cells, while Meiosis results in 4 genetically diverse daughter cells.

Front

What are homologous chromosomes?

Back

Homologous chromosomes are pairs of chromosomes that have the same structure and carry the same genes, one inherited from each parent.

Front

What happens during Prophase of Meiosis?

Back

During Prophase of Meiosis, homologous chromosomes pair up and exchange genetic material through a process called crossing over.

Front

What is a tetrad in Meiosis?

Back

A tetrad is a structure formed during Meiosis when two homologous chromosomes (each consisting of two sister chromatids) pair up.

Front

What is the significance of Metaphase in cell division?

Back

During Metaphase, chromosomes align along the equatorial plane of the cell, ensuring that each daughter cell will receive an equal and accurate distribution of chromosomes.

Front

How many cycles of cell division occur in Meiosis?

Back

Meiosis consists of two cycles of cell division: Meiosis I and Meiosis II.

Front

What is the outcome of Anaphase in Meiosis?

Back

During Anaphase of Meiosis, homologous chromosomes are pulled apart to opposite poles of the cell.

Front

What is Telophase in the context of Meiosis?

Back

Telophase is the final stage of Meiosis where the chromosomes reach the poles, and the cell begins to divide into two daughter cells.
