FLASHCARD QUESTION

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells, each with the same number of chromosomes as the parent cell.

4.

FLASHCARD QUESTION

What is meiosis?

Back

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

5.

FLASHCARD QUESTION

Front

Why is DNA replication important before cell division?

Back

DNA replication is crucial to ensure that each daughter cell receives an identical set of genetic information.

6.

FLASHCARD QUESTION

Front

What is crossing over in meiosis?

Back

Crossing over is the exchange of genetic material between homologous chromosomes during prophase I of meiosis, increasing genetic variation.

7.

FLASHCARD QUESTION

Front

What is the significance of genetic variation?

Back

Genetic variation is important for evolution and adaptation, as it provides a population with diverse traits.
