Best Answer

Meiosis is a special type of cellular division because it results in cells which have half the number of chromosomes as the original cell.

Meiosis produces 4 gametes (sex-cells) from one original cell. These gametes are involved in sexual reproduction.

Is crossing over unique to meiosis?

Yes, crossing over is unique to meiosis. It occurs during prophase I of meiosis and involves the exchange of genetic material between homologous chromosomes to increase genetic variation in the offspring. Crossing over does not occur in mitosis.


What are the phases of meosis?

Meiosis consists of two main phases: meiosis I and meiosis II. Meiosis I involves the separation of homologous chromosomes, resulting in two haploid daughter cells. Meiosis II involves the separation of sister chromatids, producing a total of four haploid daughter cells with unique genetic combinations.


Describe the differences between the original cell that undergoes meiosis and the daughter cells produced by meiosis?

The original cell that undergoes meiosis is diploid, meaning it has two sets of chromosomes. The daughter cells produced by meiosis are haploid, containing only one set of chromosomes. Additionally, the original cell undergoes two rounds of cell division to produce four daughter cells, each genetically unique due to crossing over and independent assortment.


Does meiosis involve two divisions and produces four nonidentical daughter nuclei?

Yes, meiosis involves two divisions: meiosis I and meiosis II. It results in four nonidentical daughter cells with half the number of chromosomes as the parent cell. Each daughter cell is genetically unique due to the processes of crossing over and independent assortment.


What does meiosis contain?

Meiosis is a type of cell division that results in the formation of reproductive cells with half the number of chromosomes. It involves two rounds of division (meiosis I and meiosis II) to produce four genetically unique daughter cells. Meiosis plays a crucial role in sexual reproduction by creating genetic diversity among offspring.

Name and briefly describe the stages of the two meiotic divisions of meiosis?

The two meiotic divisions are called meiosis I and meiosis II. In meiosis I, homologous chromosomes pair up and exchange genetic material in a process called crossing-over before separating, resulting in two daughter cells with half the number of chromosomes as the parent cell. In meiosis II, sister chromatids separate, resulting in four daughter cells, each with a unique combination of genes.


What are the main events of meiosis 1 and meiosis 2?

In meiosis I, homologous chromosomes pair up and exchange genetic material in a process called crossing over. The pairs then separate, leading to two daughter cells with half the number of chromosomes as the original cell. In meiosis II, the sister chromatids within each daughter cell separate, resulting in the formation of four haploid daughter cells with unique genetic combinations.

What are the stages of meosis?

Meiosis consists of two main stages: meiosis I and meiosis II. Meiosis I involves the separation of homologous chromosomes, resulting in two haploid cells. Meiosis II involves the separation of sister chromatids, resulting in four haploid daughter cells, each genetically unique.


What Best describe meiosis?

Meiosis is a two-part cell division process in organisms that sexually reproduce. Meiosis produces gametes with one half the number of chromosomes as the parent cell. There are two stages of meiosis: meiosis I and meiosis II. At the end of the meiotic process, four daughter cells are produced. Each of the resulting daughter cells has one half of the number of chromosomes as the parent cell.

In meiosis 1 what events occurs of interphase?

There is only one interphase, and it's the same as other cells: to grow, function, and replicate DNA. Meiosis is only a small part of cell cycle and interphase is not included in it. There are, however, two different phases in meiosis, such as prophase I and prophase II.
