In meiosis, daughter cells are genetically different because genetic recombination and segregation of chromosomes occur during meiosis and gives haploid gametes with half the genetic materials. hope this helps^_^.The parent cell undergoes one round of DNA replication followed by two separate cycles of nuclear division. Meiosis II is a mitotic division of each of the haploid cells produced in meiosis I. During prophase II, the chromosomes condense, and a new set of spindle fibers forms.Reproductive egg and sperm cells are known as haploid because they contain a single set of Human cells are considered diploid because they inherit two sets of chromosomes, 23 from the mother and 23 Sequencing of the human genome has yielded a wealth of new information about genetic...The "parent" cell splits into two "daughter" cells. This means that each of the new cells has a unique set of genetic information. It is this process that allows genetic diversity to occur. The egg cell is also haploid so that the DNA from the sperm and egg can combine to create a diploid cell.

Two parents are needed in sexual reproduction . During this process the nuclei of the male and female gametes are fused in order to create a Gametes contain half the number of chromosomes of all other cells in the organism. This means they are haploid . When the male and female gametes...Reproductive cells, called gametes, are different. They contain only half the full number of chromosomes—one chromosome from each pair.

Question 7: Given below is a diagram representing a stage during mitotic cell division.When the haploid cells from the parent donors come together and are fertilized, the Haploid cells have half the number of chromosomes (n) as diploid - i.e. a haploid cell contains only one Cell Division and Growth. Diploid cells reproduce by mitosis making daughter cells that are exact replicas.Most cells reproduce to form identical copies, or daughter cells, for the purpose of growth or repair. In this way, the offspring are assured to get one half of the chromosomes from the mother and one Cytokinesis, or cell division occurs, producing two haploid (n) daughter cells, each with only one set...

Meiosis is a type of cell department that reduces the collection of chromosomes in the mum or dad cell by way of half and produces four gamete cells. This procedure is required to produce egg and sperm cells for sexual replica. During copy, when the sperm and egg unite to shape a unmarried cell, the selection of chromosomes is restored in the offspring.

Meiosis begins with a mum or dad cell that is diploid, meaning it has two copies of each chromosome. The mum or dad cell undergoes one round of DNA replication adopted through two separate cycles of nuclear division. The procedure results in 4 daughter cells which can be haploid, this means that they comprise half the selection of chromosomes of the diploid dad or mum cell.

Meiosis has both similarities to and variations from mitosis, which is a cell division process in which a parent cell produces two an identical daughter cells. Meiosis begins following one spherical of DNA replication in cells in the male or feminine intercourse organs. The process is cut up into meiosis I and meiosis II, and both meiotic divisions have more than one stages. Meiosis I is a form of cell department distinctive to germ cells, while meiosis II is very similar to mitosis.

Meiosis I, the first meiotic division, starts with prophase I. During prophase I, the complex of DNA and protein referred to as chromatin condenses to shape chromosomes. The pairs of replicated chromosomes are known as sister chromatids, they usually remain joined at a central level called the centromere. A large construction referred to as the meiotic spindle additionally bureaucracy from long proteins referred to as microtubules on each side, or pole, of the cell. Between prophase I and metaphase I, the pairs of homologous chromosome form tetrads. Within the tetrad, any pair of chromatid arms can overlap and fuse in a process known as crossing-over or recombination. Recombination is a process that breaks, recombines and rejoins sections of DNA to supply new combinations of genes. In metaphase I, the homologous pairs of chromosomes align on both sides of the equatorial plate. Then, in anaphase I, the spindle fibers contract and pull the homologous pairs, every with two chromatids, away from every other and towards each pole of the cell. During telophase I, the chromosomes are enclosed in nuclei. The cell now undergoes a procedure known as cytokinesis that divides the cytoplasm of the unique cell into two daughter cells. Each daughter cell is haploid and has just one set of chromosomes, or half the total selection of chromosomes of the authentic cell.

Meiosis II is a mitotic division of each of the haploid cells produced in meiosis I. During prophase II, the chromosomes condense, and a new set of spindle fibers bureaucracy. The chromosomes begin moving towards the equator of the cell. During metaphase II, the centromeres of the paired chromatids align alongside the equatorial plate in each cells. Then in anaphase II, the chromosomes separate at the centromeres. The spindle fibers pull the separated chromosomes toward each pole of the cell. Finally, throughout telophase II, the chromosomes are enclosed in nuclear membranes. Cytokinesis follows, dividing the cytoplasm of the two cells. At the conclusion of meiosis, there are four haploid daughter cells that cross on to turn out to be either sperm or egg cells.
