meiosis, is a special type of cell division of germ cells in sexually-reproducing organisms used to produce the gametes, such as sperm or egg cells. It involves two rounds of division that ultimately result in four cells with only one copy of each paternal and maternal chromosome.
What is one result of meiosis Brainly?
The final product of Meiosis is haploid daughter cells in which each cell has 23 chromosomes. What happens in meiosis is that, the cell is divided twice and this produces four daughter cells. During this process that our sex cells are produced.
Which type of cell is a result of meiosis diploid cells?
During sexual reproduction, the process of meiosis is used to generate gametes in the form of sperm and egg cells. The process of meiosis generally begins in the diploid parent cell, that is, the cell exhibiting two chromosomes copies.
Which cell is normally produced as a direct result of meiosis *?
A sperm having half the normal species number of chromosomes. Hint: Meiosis is the process in which four cells are formed from a single cell. During meiosis, the ploidy level gets halved. Moreover, the male and female gametes are produced by the meiotic divisions, due to which they are haploid.
Why is meiosis important for organisms?
Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.
What is one result of meiosis quizlet?
The result of meiosis is 4 gametes, or sex cells, that each contain half of the genetic information in the parent organism. A process in cell division during which the number of chromosomes decreases to half the original number.
Which phase of cell division is shown Brainly?
the answer would be anaphase. in prophase, the chromosomes are still together. in telophase, the cell itself is separating in two.
What is the result of meiosis two?
The result of meiosis II is the formation of four unique cells, each carrying a new assortment of genes and chromosomes, and each with half the number of original chromosomes. … The second cell division completes, resulting in four haploid cells or gametes.
What is the difference between meiosis 1 and meiosis 2?
There are two divisions in meiosis; the first division is meiosis I: the number of cells is doubled but the number of chromosomes is not. This results in 1/2 as many chromosomes per cell. The second division is meiosis II: this division is like mitosis; the number of chromosomes does not get reduced.
Why can’t meiosis occur in a haploid cell?
No meiosis can occur in haploid cells. A haploid organism (n) produces gametes (n) by mitotic division. These gametes (n) are then fused by fertilization to produce a zygote which is diploid. This zygote or diploid cell then undergoes meiotic division to again produce a haploid organism (n).
Which statement is true of both mitosis and meiosis?
o, the correct statement is ‘In both mitosis and meiosis the replication of DNA and chromosomes occurs at the same stage. ‘
What happens immediately after mitotic cell division?
Once mitosis is complete, the entire cell divides in two by way of the process called cytokinesis (Figure 1).
