What is meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically diverse daughter cells, each with half the number of chromosomes of the original cell.

What are sister chromatids?

Back

Sister chromatids are two identical copies of a single chromosome, connected by a centromere.

True or False: Sister chromatids are exact copies of each other.

Back

True

What happens during Prophase I of meiosis?

Back

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

Front

What is the result of meiosis in terms of genetic variation?

Back

Meiosis produces daughter cells that are genetically different from each other due to crossing over and independent assortment.

What is the difference between meiosis and mitosis?

Back

Meiosis results in four genetically diverse daughter cells with half the chromosome number, while mitosis results in two identical daughter cells with the same chromosome number.

What is crossing over?

Back

Crossing over is the exchange of genetic material between homologous chromosomes during Prophase I of meiosis, leading to genetic variation.

What is the role of the nucleus in a cell?

Back

The nucleus is the control center of the cell, containing the cell's genetic material (DNA) and regulating gene expression.
