Question

Rotifers produce

• A. Diploid amictic eggs
• B. Haploid mictic eggs
• C. Both A and B
• D. None of the above

Answer 1

The correct option is C Both A and B

In the rotifers are small but abundant freshwater animals. In them, reproduction is usually sexual and the sexes are separate. They produce two type of egg in different seasons. One egg type is called as diploid amictic, produced in the early spring and the embryo develops without fertilization (parthenogenesis). When the population reaches a peak in the early summer, the second type of egg is produced. If unfertilized, this egg, which is called as mictic, results in males. As the male population increases, most mictic eggs become fertilized in winters and gives rise to the amictic females of the next spring.
