Why is it necessary for meiosis to produce with fewer chromosomes?

∙ 6y ago
Meiosis is necessary for producing cells with fewer chromosomes because these are the cells that will form gametes which are the reproductive cells needed for sexual reproduction. During meiosis the number of chromosomes in the parent cell divides in half producing four daughter cells each with half the number of chromosomes as the parent cell. This halving of chromosomes is necessary for sexual reproduction to occur because when two gametes combine the resulting cell has a full set of chromosomes restoring the original chromosome number of the parent cell. Without meiosis sexual reproduction would not be possible.

If it did not, the chromosome number would double in each generation.

La réduction du nombre de chromosomes est pour produire des gamètes haploïdes qui, lorsqu'ils se combinent lors de la fécondation, restaureront le nombre diploïde de chromosomes dans le zygote (la cellule œuf). Si la méiose ne produisait pas de cellules avec moins de chromosomes, le nombre de chromosomes dans l'espèce doublerait à chaque génération, ce qui entraînerait des anomalies chromosomiques et des problèmes de développement chez les descendants.

Why meiosis produce cells with fewer chromosomes?
Sexual reproduction joins two cells that each have half the total chromosome number.
Which correctly describes a difference between the male and female reproductive systems?
Females produce fewer gametes.
What do you call a human cell with fewer or more than 46 chromosomes?
The cell is aneuploid, and the condition is aneuploidy.The human haploid number is 23. So a diploid cell (one with two sets of chromosomes, one set from each parent) has 46 chromosomes.Occasionally a mistake occurs in cell division, and the cell does not detect the mistake and stop the division. The mistake involves attachment of spindle fibers to centromeres. The consequence is that, instead of two chromosomes separating and going to opposite poles at anaphase, both members of a pair travel to the same pole. One daughter cell therefore lacks a chromosome, and one has an extra copy.Among the conditions caused by this non-disjunction are Down's syndrome and Klinefelter's syndrome.

Why is it necessary for sex cells to have fewer chromsomes then regular cells?
So that when the process of the child being made comes the child will still have 46 chromosomes.
Can organisms with fewer chromosomes reproduce more easily than organism with more number of chromosomes?
can organisms with fewer no of chromosome reproduce more easily than organim with more
Why does a fruit fly cell have fewer chromosomes than a human cell?
Fruit flies have fewer chromosomes in their bodies because of the simplicity of their life. Having only few purposes, their DNA needs fewer chemical reactions to keep it alive for its life span.
Why is it necessary for sex cells to have fewer the number of chromosomes regular cells?
The sex cells must combine with each other to make a whole. Each gamete starts out with half of the regular cell so that it can combine to make a whole. If they start out like somatic cells, the result will be double the chromosomes for the offspring.
What is the proportion of births where an infant is born with more or fewer chromosomes than 46?

How many chromosomes does a donkey have?
The mule has 63 chromosomes. A donkey has 31 pairs and a horse 32 pairs so the mule or hinny inherits 31 from its donkey parent (usually the father) and 32 from its horse parent. The fact that the donkey has fewer chromosomes than the horse is thought to be the reason why hinny-breeding (where the father is the horse) is more difficult, resulting in a high rate of spontaneous abortion. If two species are to be crossed, therefore, the male should be the one with fewer chromosomes.

Why do female and male sex cells have fewer chromosomes than the body cells?
The Y chromosome is found in males only. Females have XX chromosomes whereas males have XY chromosomes. That is why they are different, because an XY cannot be female and an XX cannot be male.
