Sexual and Asexual Reproduction and Variation
... Sexual Reproduction • Sexual Reproduction is the creation of offspring using gametes which causes variation. • Sexual Reproduction involves two organisms. Male and female gametes (sex cells) join together to create a new cell. This develops into a new individual. The joining of gametes is called fe ...
