Some species of rotifers undergo parthenogenesis, which means that __________.

• A. their larval stage of development looks completely different from the adult stage
• B. they shed their exoskeleton as they grow
• C. each individual functions as both male and female in sexual reproduction by producing sperm and eggs
• D. during development of adult forms, some of the organs that were bilateral are reduced in size or are lost on one side of the body
• E. the species consist only of females that produce more females from unfertilized eggs

Answer: (E)

Verified step by step guidance

1. Understand the concept of parthenogenesis: Parthenogenesis is a form of asexual reproduction where an organism develops from an unfertilized egg. This process is common in some invertebrates, including certain species of rotifers.
2. Identify the characteristics of parthenogenesis: In parthenogenesis, there is no need for fertilization by a male. The offspring are typically clones of the mother, meaning they are genetically identical.
3. Analyze the options given in the problem: The options describe various biological processes, but only one aligns with the definition of parthenogenesis.
4. Evaluate the correct option: The correct option states that the species consist only of females that produce more females from unfertilized eggs, which directly matches the definition of parthenogenesis.
5. Conclude the reasoning: Since parthenogenesis involves reproduction without fertilization, resulting in offspring that are genetically identical to the mother, the correct answer is the one that describes this process accurately.
