Gametes6
  • Sexual reproduction involves the combining and mixing of genetic traits: specialized cells known as gametes combine to form offspring that inherit traits from each parent. (artandpopularculture.com)
  • This is in contrast to asexual reproduction where an organism reproduces without involving gametes and the resulting offspring is a clone of the parent. (biologyonline.com)
