WebIn humans (2 n = 46), who have 23 pairs of chromosomes, the number of chromosomes is reduced by half at the end of meiosis I ( n = 23). Prophase I During prophase I, chromosomal condensation allows chromosomes to be viewed under the microscope. Homologous chromosomes are important in the processes of meiosis and mitosis. They allow for the recombination and random segregation of genetic material from the mother and father into new cells. Meiosis is a round of two cell divisions that results in four haploid daughter cells that each contain half the number of chromosomes as the parent cell. It reduc…

Pairs of chromosomes that are the same length and shape (homologous chromosomes) have paired together. The homologous chromosomes are different colors from each other, representing that they are not genetically identical. WebAs in the previous figure, only one pair of homologous chromosomes is shown.
