What must happen before meiosis can begin four gametes must be produced?

What must happen before meiosis can begin a four haploid cells are produced?

Answer Expert Verified

Meiosis is a process which takes one diploid cell (46 chromosomes) and makes 4 haploid cells (23 chromosomes). In order to do this, the DNA must divide. This is because it takes 46 chromosomes, to make 4*23 chromosomes, or 92. We see here that the amount of chromosomes must double before meiosis.

What must happen before mitosis begins?

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 must happen before meiosis can begin apex Brainly?

there must be replication of chromosomes, replication of organelles, formation of tubulin protein so that it can form spindles in meiosis!

Why is meiosis II needed for gamete egg and sperm production?

Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction. … Meiosis begins with a parent cell that is diploid, meaning it has two copies of each chromosome.

What happens to DNA in meiosis?

Specifically, meiosis creates new combinations of genetic material in each of the four daughter cells. These new combinations result from the exchange of DNA between paired chromosomes. Such exchange means that the gametes produced through meiosis exhibit an amazing range of genetic variation.

How much DNA replication is required before meiosis can begin?

The initiation of meiosis requires both intrinsic and extrinsic signals. Meiosis is characterized by one round of DNA replication followed by two rounds of cell division, resulting in haploid germ cells.

What is the correct order of these meiotic events?

The correct order of mitotic events which occur during meiosis is: Formation of synaptonemal complex, recombination, separation of homologous chromosomes, separation of sister chromatids.
