Which type of reproduction allows for greater genetic diversity in offspring?

Sexual reproduction is the mechanism that promotes greater genetic diversity in offspring. This process involves the combination of genetic material from two parents, typically through the fusion of male and female gametes (sperm and egg cells). The mixing of genes during fertilization leads to offspring that have unique combinations of DNA, which increases variability in traits among individuals of a population.

This genetic variation is vital for evolution and adaptation, as it provides a wider array of traits that could be advantageous in changing environments. In contrast, asexual reproduction, vegetative propagation, and cloning typically result in offspring that are genetically identical or very similar to the parent organism, limiting genetic diversity. Consequently, sexual reproduction is the dominant method for species evolution and adaptation, making it crucial for the survival and resilience of populations over time.
