AP Bio Insta-Review Topic 5.1*: Meiosis

Front

What phase does independent assortment take place?

Back

Metaphase I

Front

If parent cell is 2N, what is the ploidy of the daughter cell?

Back

1N

Front

Describe the daughter cells in meiosis vs parent cell.

Back

The daughter cells are unique and haploid.

Front

What phase does crossing over take place?

Back

Prophase I

Front

How many rounds of DNA replication occur during meiosis?

Back

1

Front

What is the main purpose of meiosis?

Back

To produce gametes with half the number of chromosomes.

Front

What is the difference between diploid and haploid cells?

Back

Diploid cells have two sets of chromosomes (2N), while haploid cells have one set (1N).

Front

What is crossing over and why is it important?

Back

Crossing over is the exchange of genetic material between homologous chromosomes during Prophase I, increasing genetic diversity.

Front

What are homologous chromosomes?

Back

Chromosomes that are similar in shape, size, and genetic content, one inherited from each parent.

Front

What is the significance of genetic variation in meiosis?

Back

Genetic variation is crucial for evolution and adaptation, allowing populations to respond to environmental changes.
