Because of genetic recombination and this is done in three ways. The independent orientation of chromosomes at prometaphase, crossing over and the process of random fertilization all insure a good recombination of genetic material.
contributes to genetic variation.
Meiosis occurs in the reproductive cells to form male and female gametes. For sexual reproduction meiosis is essential. Genetic advance is achieved by crossing over in chromosomes during meiosis, hence meiosis helps in evolution of races in plants.Meiosis occurs in the reproductive cells to form male and female gametes.

Meiosis produce 4 heploid cell and that four cell contain single strand chromosome which is 23 and nt 46 so it give variation and evolution
Meiosis is divided into Meiosis I and Meiosis II because the initial cell divides twice producing four genetically different sex cells (gametes) Each time a cell divides, it goes through Prophase, Metaphase, Anaphase, and Telophase. See the link below for a diagram showing the process.
Crossing over is one of the most important events in meiosis because?
Meiosis is when the male gene and the female gene combine chromosomes to make a child or offspring. This increases the diversity of genes in an individual, and allows that diversity to spread through the population, thus effecting evolution.
Meiosis produces new varieties .

Meiosis takes place in sexual reproduction and genetic variations takes place in sexual reproduction. Genetic variations lead to evolution to new species.
because it makes sex cells, so humans and/or animals can produce offspring.
