Sexual Reproduction
Sexual reproduction involves the fusion of male and female reproductive cells, or gametes, to produce a new organism. In most animals, including humans, this process involves the joining of a sperm cell from the male with an egg cell from the female. The resulting offspring inherits genetic material from both parents, leading to genetic diversity within the population.Asexual Reproduction
Asexual reproduction involves the production of offspring from a single parent, without the involvement of gametes. This can occur through various methods such as budding, fragmentation, or spore formation. The offspring produced through asexual reproduction are genetically identical to the parent, leading to the formation of clones.Study Guide
