Question

Which statement BEST describes a process that provides an increase in genetic diversity that promotes evolution?

Asexual reproduction results in the formation of a large number of diploid offspring.

Cytokinesis unequally divides the contents of the cytoplasm into daughter cells.

Meiosis results in the formation of gametes that are then randomly fertilized.

Mitosis produces daughter cells that obtain genetic information from a single parent cell.

Answer 1

The correct option is Meiosis results in the formation of gametes that are then randomly fertilized.

The process of meiosis forms genetically different gametes and random fertilization occurs by fusion of egg and sperm, which forms different zygotes. In the process of meiosis, the source of genetic variability is random Segregation of maternal and paternal chromosomes. Meiosis and fertilization both process carry genetic information into new combinations. Therefore, produced offsprings are genetically different. This variability increases genetic diversity, which promotes the process of evolution.
