Bio- Meiosis

What are chromosomes that occur in homologous pairs called?

They are referred to as diploid chromosomes.

What do sister chromatids do during mitosis?

Sister chromatids separate to produce two new nuclei.

What is the human diploid number?

The human diploid number is 46.

What is a haploid cell?

A cell that contains a single copy of chromosomes, represented by n.

What is the process called when tetrads exchange portions of their chromatids?

This process is known as crossing over.

How many haploid cells are created at the end of meiosis?

Meiosis creates 4 haploid cells.

What occurs during Meiosis 1?

Chromosomes duplicate and tetrads form, leading to crossing over.

What is a tetrad?

A tetrad is a pair of homologous chromosomes.

What happens to chromosomes during the second division of meiosis without DNA duplication?

Chromosomes line up in the center, then separate to form four haploid cells.

How does meiosis produce cells different from each other and the original?

Through processes like crossing over and independent assortment.

What is mitosis?

Mitosis is the process of cell division that results in two identical daughter cells from a single parent cell.

What is meiosis?

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

How many daughter cells are produced in mitosis?

Mitosis produces 2 daughter cells.

How many daughter cells are produced in meiosis?

Meiosis produces 4 daughter cells.

Are the daughter cells in mitosis identical to the parent cell?

Yes, the daughter cells produced by mitosis are genetically identical to the parent cell.

Are the daughter cells in meiosis identical to the parent cell?

No, the daughter cells produced by meiosis are not identical to the parent cell due to genetic recombination.

What is the key purpose of mitosis?

The key purpose of mitosis is growth, repair, and asexual reproduction.

What is the key purpose of meiosis?

The key purpose of meiosis is to produce gametes for sexual reproduction.

What is a significant feature of meiosis that does not occur in mitosis?

Crossing over and independent assortment occur in meiosis, increasing genetic diversity.

Does mitosis involve homologous chromosomes?

No, mitosis involves the division of sister chromatids, not homologous chromosomes.
