Which statement best describes this process?


The process introduces genetic variation in sexually reproducing organisms.


The process maintains genetic information in asexually reproducing organisms.


The process increases the number of chromosomes in sexually reproducing organisms.


The process maintains the number of chromosomes in asexually reproducing organisms.

Answer 1

The process is crossing over during meiosis, which introduces genetic variation in sexually reproducing organisms. Crossing over exchanges chromosome segments between homologous chromosomes, creating new allele combinations.
