Front

What is mitosis?

Back

A type of cell division that results in two identical daughter cells, used for growth and repair.

Front

What is meiosis?

Back

A type of cell division that reduces the chromosome number by half, producing four genetically diverse gametes.

Front

What is the purpose of mitosis?

Back

To produce new cells for growth, repair, and asexual reproduction.

Front

What is the purpose of meiosis?

Back

To produce gametes (sperm and eggs) for sexual reproduction.

Front

What is genetic variation?

Back

Differences in DNA sequences among individuals, which can lead to different traits.

Front

What is crossing over?

Back

The exchange of genetic material between homologous chromosomes during meiosis, contributing to genetic diversity.

Front

What is the Law of Independent Assortment?

Back

The principle that alleles for different traits are distributed to sex cells (& gametes) independently of one another.

Front

How many chromosomes do humans have in their body cells?

Back

46 chromosomes (23 pairs).
