A. increases the genetic variation

that's why individuals don't look like their partents. This process is called crossing-over

During meiosis, homologous chromosomes exchange genetic material. This exchange of genetic material - A. increases the genetic variation.

During meiosis, homologous chromosomes may exchange genetic material during a process called "crossing over."

  • Crossing over takes place during the pachytene stage of Prophase I of Meiosis I where the non-sister chromatids of homologous chromosomes exchange genetic material
  • this results in recombination of the genetic material and creates a new genetic combination.
  • This results in variations, which can be beneficial to the offspring providing a better survival advantage.

So, the correct answer is Crossing over produces new combinations of genes on alleles, increasing genetic variation.
