Given the end results of the two types of division, why is it necessary for homologs to pair during meiosis and not desirable for them to pair during mitosis?

Respuesta :

Answer:

Meiosis is a reduction division.The formation of haploid chromosomes at  the end of meiosis, from formation of bivalent, at late pro phase 1,and eventual  easy alignments on  spindles for   separation at meta phase of the two stages   at the end of meiosis 1 and 2 allow for easy paring and  recombination to form new  haploid  cells at the end of  meiosis .

However, mitosis is a multiplication division(2n) the chromosome numbers are double during division;therefore it will evidently mechanically hard   for perfect alignments and pairing of the chromosomes   that will lead to  formation of  identical  daughter cells of   mitosis if homologous chromosomes  were paired.

The unparing of   chromosomes  during meta phase  ensures that only centromere  division is needed  for  distribution of  similar chromosomes compliments of the parents to the new daughter cells.

Explanation:

As during the division, the number of the chromosomes is reduced to haploids complements. This is achieved by the synapsis of chromosomes in subsequent separation.

What is meiosis ?

Meiosis states a type of division of the cells where the germ-cell in the reproducing organism is used  for egg cells. It seems difficult to genetically identical the daughters to form the mitosis. if the homologous chromosomes are paired.

Having a chromosomes unpaired in metaphase of the mitosis, only the centromere division is needed for the daughter cells to then eventually get identical chromosomal complements.
