The process that increases genetic variation within a population of earthworms is: d. Sexual reproduction
Sexual reproduction introduces genetic diversity within a population because it involves the fusion of gametes (sperm and egg cells) from different individuals. During sexual reproduction, genetic material from two different parents combines through processes like meiosis, crossing over, and random assortment of chromosomes, leading to the creation of genetically unique offspring with combinations of traits from both parents. This variability contributes to genetic diversity within the population, allowing for adaptation and evolution to changing environmental conditions.
