Mitosis and Meiosis

Front

What is mitosis?

Back

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

Front

What is meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, producing four genetically diverse gametes (sperm or eggs).

Front

What are the stages of mitosis?

Back

The stages of mitosis are prophase, metaphase, anaphase, and telophase.

Front

How many chromosomes do humans have?

Back

Humans have a total of 46 chromosomes in their somatic cells.

Front

What is the role of DNA in the nucleus?

Back

DNA contains the genetic instructions for the development, functioning, growth, and reproduction of all known living organisms.

Front

What is the difference between somatic cells and gametes?

Back

Somatic cells are body cells that are diploid (containing two sets of chromosomes), while gametes are reproductive cells (sperm and eggs) that are haploid (containing one set of chromosomes).

Front

What chromosome combination results in a male?

Back

The chromosome combination XY results in a male.

Front

What is the significance of crossing over in meiosis?

Back

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

Front

What is the end result of meiosis?

Back

The end result of meiosis is four genetically diverse haploid gametes.

Front

What is a diploid cell?

Back

A diploid cell is a cell that contains two complete sets of chromosomes, one from each parent.
