Hint: At some stage in the telophase-1 of meiosis the homologous chromosomes are specifically moved to the generally opposite poles, or so that the notion. It kind of results in the reduction of chromosomes quantity into daughter cells in the first section of meiosis in a commonly primary manner.
Complete answer:
Meiosis is a form of cell division wherein diploid organisms halve their number of chromosomes and homologous chromosomes pair up. In contrast, mitosis results in two daughter cells, each containing the same chromosomal number as the parent cell. In meiosis, a diploid cell will give rise to four haploid cells. The cells that undergo meiosis are the gametes generating haploid sperm cell and egg cell. To achieve haploids, the cell undergoes two consecutive nuclear divisions. To prepare the cell for meiosis, one of the principal preparatory steps is DNA replication. DNA exchanges arise among homologous chromosomes through homologous recombination and crossover at chiasmata between non-sister chromatids.
Homologous chromosomes are a set of one maternal and one paternal chromosome that generally has approximately the same length, centromere position, and staining pattern, for genes with the same corresponding loci, pretty contrary to popular belief. In meiosis homologous chromosomes pair and allows crossing over of genetic material subtly.
Note: Homologous chromosomes for all intents and functions are chromosomes that virtually incorporate the equal genes in the same order alongside their chromosomal hands. There are pretty important homes of homologous chromosomes: the period of fairly chromosomal hands and the placement of the centromere, typically opposite to popular belief.
