self fertilization vs cross fertilization

  • Difference between Self fertilization and cross

    Jul 16 2008 · Both self- and cross-fertilization are forms of sexual reproduction and involve the fusion of gametes. Self-fertilization is when those two gametes come from the same individual while cross-fertilization is when they come from two different individuals. While plants more commonly self-fertilize many hermaphrodite animals can as well.
