Sexual reproduction appears to be absent in bdelloid rotifers.Which of these,if found in this group,would bring into question the idea that they reproduce ONLY asexually?
A)female rotifers with eggs
B)significant differences of two different alleles among different populations (one population having mostly allele A and one having mostly a).
C)cells in which meiosis occurs
D)related groups (not bdelloid rotifers)which reproduce both sexually and asexually.

Question

Quizplus · Accepted Answer

Cells in which meiosis occurs are necessary for sexual reproduction, so if they were found in bdelloid rotifers, it would suggest that they are capable of sexual reproduction. The presence of female rotifers with eggs (A) could be explained by asexual reproduction via parthenogenesis, and the presence of significant allele differences (B) could be explained by genetic drift rather than the occurrence of sexual reproduction. The presence of related groups that reproduce sexually and asexually (D) does not necessarily imply that bdelloid rotifers are also capable of sexual reproduction.
