10BD 12-1: Meiosis

Front

What is the first stage of Meiosis called?

Back

Prophase I

Front

During which stage of Meiosis does crossing over occur?

Back

Prophase I

Front

At what points are the cells considered haploid?

Back

4, 5, 6

Front

Which of the following is a key difference between Meiosis and Mitosis?

Back

Meiosis involves two rounds of cell division, while Mitosis involves one.

Front

How can errors during Meiosis lead to genetic disorders?

Back

Errors can lead to an incorrect number of chromosomes, causing disorders like Down syndrome.

Front

Define Meiosis.

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically diverse gametes.

Front

What is crossing over in Meiosis?

Back

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

Front

What are homologous chromosomes?

Back

Homologous chromosomes are pairs of chromosomes, one from each parent, that are similar in shape, size, and genetic content.

Front

What is the significance of Meiosis in sexual reproduction?

Back

Meiosis produces gametes, which are essential for sexual reproduction and genetic diversity.

Front

What is the difference between haploid and diploid cells?

Back

Haploid cells have one set of chromosomes (n), while diploid cells have two sets (2n).
