Which of the following is a type of asexual reproduction found in some fish and shellfish?

  1. Budding

  2. Fragmentation

  3. Parthenogenesis

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Budding, fragmentation, and parthenogenesis are all types of asexual reproduction found in some fish and shellfish. Budding involves the formation of a new individual from an outgrowth of the parent's body. Fragmentation involves the breaking of the parent's body into several pieces, each of which can develop into a new individual. Parthenogenesis involves the development of an embryo from an unfertilized egg.
