Sea stars (starfish) can reproduce asexually by fragmentation if their arms are cut off, or sexually by releasing sperm and eggs into the water. Which of these is the major difference between asexual and sexual reproduction in sea stars? 

• The chromosome number is reduced in sea stars during sexual reproduction. 
• The number of chromosomes is increased in sea stars during sexual reproduction.
•  The appearance of the sea stars is changed as a result of asexual reproduction.
• There is no genetic variation in the sea stars as a result of asexual reproduction.
