What is meiosis?

Back

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

Front

Where does meiosis take place in males?

Back

Meiosis occurs in the testes.

Front

What is the diploid chromosome number?

Back

The diploid chromosome number is the total number of chromosomes in a somatic cell, represented as 2n. For example, in humans, the diploid number is 46.

Front

What is the haploid chromosome number?

Back

The haploid chromosome number is half of the diploid number, represented as n. In humans, the haploid number is 23.

Front

What is the role of the spindle apparatus during cell division?

Back

The spindle apparatus helps separate chromosomes during cell division by attaching to the centromeres and pulling them apart.

Front

What is the difference between mitosis and meiosis?

Back

Mitosis results in two identical daughter cells, while meiosis results in four genetically diverse gametes.

Front

What is a chromatid?

Back

A chromatid is one half of a duplicated chromosome, which is joined to its sister chromatid by a centromere.

Front

What is a cell plate?

Back

A cell plate is a structure that forms during cytokinesis in plant cells, leading to the separation of the two daughter cells.

Front

What is fertilization?

Back

Fertilization is the process where a sperm cell and an egg cell combine to form a zygote.

Front

What is the significance of genetic diversity in meiosis?

Back

Genetic diversity is important for evolution and adaptation, as it allows populations to respond to environmental changes.
