Which of the following is not the purpose of meiosis?
Correct This answer choice is correct because multiplication of somatic cells does not reduce the chromosome number and is not the purpose of meiosis. If an animal egg were fertilized by many sperm, there would be many copies of the organism’s chromosomes in the egg. What prevents this from happening?
What are the purposes of meiosis?
Therefore the purpose of meiosis is to produce gametes, the sperm and eggs, with half of the genetic complement of the parent cells.
What is not a purpose of mitosis?
Both sexual and asexual organisms go through the process of mitosis. It happens in the cells of the body known as the somatic cells and produces cells related to growth and repair. Mitosis is essential for asexual reproduction, regeneration, and growth. It does not make sex cells or gametes.
What is the purpose of meiosis quizlet?
The purpose of meiosis is to reproduce the normal diploid cells to haploid cells and to make egg and sperm.
What are the key features of meiosis?
Features of Meiosis
- It results in the formation of four daughter cells in each cycle of cell division.
- The daughter cells are identical to the mother cell in shape and size but different in chromosome number.
- The daughter cells are haploid.
- Recombination and segregation take place in meiosis.
Why do organisms need both mitosis and meiosis?
Mitosis and meiosis both involve cells dividing to make new cells. This makes them both vital processes for the existence of living things that reproduce sexually. Meiosis makes the cells needed for sexual reproduction to occur, and mitosis replicates non-sex cells needed for growth and development.
What are two functions of meiosis?
Two key functions of meiosis are to halve the DNA content and to reshuffle the genetic content of the organism to generate genetic diversity among the progeny.
What must occur before mitosis takes place?
Before a cell can enter the active phases of mitosis, however, it must go through a period known as interphase, during which it grows and produces the various proteins necessary for division.
What is produced by mitosis?
Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division.
