Meiosis

Front

What is Meiosis?

Back

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

Front

What is Crossing Over?

Back

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

Front

What is a Diploid cell?

Back

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

Front

What is a Haploid cell?

Back

A haploid cell is a cell that contains only one complete set of chromosomes, typically found in gametes (sperm and egg cells).

Front

What is the main purpose of Meiosis?

Back

The main purpose of meiosis is to produce gametes for sexual reproduction, ensuring genetic diversity.

Front

What is the difference between Mitosis and Meiosis?

Back

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

Front

What is Genetic Recombination?

Back

Genetic recombination is the process by which genetic material is physically mixed during meiosis, leading to new combinations of alleles.

Front

What is a Tetrad?

Back

A tetrad is a structure containing four chromatids that forms during meiosis when homologous chromosomes pair up.

Front

What occurs during Prophase I of Meiosis?

Back

During Prophase I, homologous chromosomes pair up and crossing over occurs, exchanging genetic material.

Front

What is the significance of Genetic Diversity?

Back

Genetic diversity is important for the survival of species as it allows populations to adapt to changing environments.
